How to Build a Human

Since you guys were talking about the human body this week and last week, I thought I'd share a fabulous French website!

I hope you enjoy the GIF image with the small animations and funny shapes we all have before we are born.

This is the cycle of a human being made!

Each number represents a different week that passes by and each letter a seperate part of the baby that develops.



Happy Studying!

See you again soon,

TWINS AND IDENTICAL TWINS

TWINS

 

 

 

 

 

 

            Human twins are individuals who share the uterus in the same pregnancy as often, but not necessarily, are conceived and born while almost simultaneously.

IDENTICAL OR MONOZIGOTICS TWINS:

 

            At fertilization of an egg with a sperm a single zigote is formed and divided into two embryos.

 

In embryo splitting DNA is divided into identical copies, so the twins share their genes, so they are always the same sex.

 

MONOZIGOTICS TWINS ARE REALLY IDENTICAL?

 

Research in identical twins discover that over the years become differentiated by environmental factors such as smoking, diet, physical activity,
environment ...

Also sometimes the differences of identical twins are due to small variations in chemical signatures of DNA.

 

DIFERENCES BETWEEN TWINS AND IDENTICAL TWINS:

 

           Fraternal twins or twins como from two eggs fertilized by two diferent sperm and therefore have different genetic load.

            Identical twins come from a single egg fertilized by a single sperm, the embryo divides resulting in two separate fetuses, but with the same genetic load. 

 

 

CIRCULATORY SYSTEM

The circulatory system is the blood and the heart  .Do that circulate blood throughout the body.The system you also leads unidirectionally toward the heart to the heart and blood pump back out through the body.

The main function of the circulatory system is to pass nutrients .

*Closed circulatory system: In this type of circulatory system blood travels through the interior of a network of blood vessels, without leaving them.

*Open circulatory system: In this type of circulation system in which blood is not always contained in a network of blood vessels.

*Simple blood circulation, blood passes once through the heart at every turn . 

*Double circulation, blood passes twice through the heart at every turn.

Hello today i am going to talk about the twins.
                           

The twins are two persons usually are two girls or two boys.
The twins are not identical twins.
The twins started in one egg.
The identical twins produced in the same pregnancy.

Identical twins share the same DNA.
The differences of the twins and the identical twins are:the identical twins are the same sex and the twins dont have to be necessarily the same sex.

The respiratory system

 

The respiratory system have 6 parts

 

 

Nostrils:Are 2 separate by a Wall cavities  conected by the outside.

 

Trachea:Going through the pharynx and bronchi.

 

Pharynx:It is a form of tuve and helps us breathe

 

Larynx:Pharynx comunites with the windpipe

 

Bronchi:Is one of the 2 passages of the lungs

 

My part that I find most important

 

 

The lungs is a part that is very importat because if we had lungs and would have died

 

 

 

OTHER RESPIRATORY SYSTEM ALSO THERE ARE OTHERS: DIGESTIVE SYSTEM

IDENTICAL TWINS

 

I`m going to write something of the identical twins

 

 

 

 

 

 

Imformation

 

 

 

• The identical twins are not identical.

 

• The identical twins produced in the same pregnancy.

 

 

• In the gut are in the same bag.

 

 

• Almost always the identical twins usually are boy and boy or girl and girl but the twins almost always are boy and girl .

 

Twins animals

 

 

 

Information

 

 

• The animals can also be twins

 

• Twins animals reproduce almost like humans

 

 

• MORE IMFORMATION OF IDENTICAL TWINS:

 

 

Some times the identical twins grow in the same person,because the cell is not entirely.

 

 

 

Some times the identical twins have the mirrow efect:

that is : Some times one is left hunded and the other is right

Twins by Patricia Bauer

               

                                          TWINS 

Hello  my  name  is  Patricia  Bauer 

now  I am  going  to  talk  you  about twins .   

  Are the   twins identical ?    

Yes ,  becuse  they  come  from  the same  placenta  and they have  the same genes 

But  some  how  they  like  different  things .

have  the  twins  the  same  sex  ?

Yes  they  have  the  same  sex

if   they  have different sex  is a twin 

(mellizo )

                         triplts twins                    

how  many  twins  brothers  can  there  be in a placenta ?

If there are   more  than  2  brothers ,

for example if there are are 3 brothers

and are borned the same day that

would not be twins this will be triplets 

twins only we can be 2 . 

                       

                   mini-outline -dictyonary

twins -two brothers -gemelos

triplets twins -3 brothers - trillizos

twin -2 brothers -diferent sex -millizos

                                     Do you have any question ?

How does identical twins are created?

Identical twins happen when a fertilized egg splits into two separate babies – usually whithin the first twelve days of mom’s pregnancy. After twelve days, the egg may not split entirely and result in conjoined twins.

Are they really identical?

There are two main factors that cause identical  twins not to be trually identical:

·     Identical twins share the same DNA – but don’t have identical DNA. When the egg splits into two halves to form identical twins, the DNA may not divide equally between the two cells. The basic concept is similar to when you cut an apple in half, the two halves may not look the same.

·     Enviromental factors both prenatal  after  the babies are born.

What are the differences between twins and identical twins?

Identical twins will almost always be of the same sex however, non identical  twins don’t have to be necessarily of the same sex, they can be a girl and a boy. 

Here I have copy a picture and a video about twins, I hope you like it!

TWINS

TWINS

Twins can either be monozygotic (identical), meaning that they develop from one zygote that splits and form two embryos,or dizygotic (fraternal) meanming that they develop from two eggs,each fertilized by separatw sperm cells.

CHARACTERISTICS

-The twins are not identical twins
-The twins start in one egg
-Some twins can be together because reproduction in not even finished

Hello, today I am going to talk about the twins.
The twins are babies that born in the same delivery.

Always are very similar, but not the same.
How there are created?
When a fertiled egg splits into two separate babies, usally within the first twuelve days of mom's pregnancy. After twuelve days, the egg may not Split entirely and result in cojoined twins.
In my opinion is so difficult when this process happens. Do you imagine?
                                                                  
        Are the twins identical?
No, there not. Sometimes one of the twins is good at maths and bad at sapainsh language and the other is good at spainsh language and bad at maths, or one is good at drawing and the other is horrible. This happens because if you put together the brains of the twins can be a Smart brain. This is the reason of one do a thing good an the other bad and the other twin the opposite.

Identical Twins have almost always the same sex. There have been 3/5 documented cases of opposite sex identicaltwins. This happens in a set of identical boys, when one twin "drops" or "looses" a Y chromosome, resulting in a single chromosome, or an XO chromosome. Whithout a Y chromosome, the twin becomes a girl with a single chromosome, and will have Turner's Syndrome. Turner's Syndrome itself is not that a uncommon, ocurring in about 1 of 2500 live female births.

                             TWINS

Information: 

we called twins to the two or more living things that born from one gestation.This occurs in the species that in the moment of the delivery it's usual that only one baby born, thats the case of humans.

Characteristics of twins: 

Human twins are babies who share the uterus in the same pregnancy,as often,they born at the same time and together.when a fetus develops only in the matrix, which is the usual case , it says pregnancy is simple but in this case there are less probabilities to complete the time of a common pregnancy.

Types of twins: there are two types of twins depending in how they past the gestation:

1. Monozygotic twins: when a normal embrion originated from the fecundation of an ova and a sperm divides into two parts accidentaly.
2. Dizygotic twins: the ones that born from diferent fecundations

THIS IS THE END SO I HOPE YOU LIKE THIS PROJECT, BYE!!!!!

TWINS

•The term twin most notably refers to two individuals (or one of two individuals) who have shared the same uterus.

~IDENTICAL TWINS: occur when one egg is fertilized by one sperm and the egg splits into two embryos. They will have the same blood type, eye color, genedar and DNA.

~FRATERNAL TWINS: ocurr when two eggs are each fertilized by a diferent sperm creating two babies. Thes twins are no more geneticaly alike than any other brither or sister they just happen to be wombmates.

TWINS

TWINS

The correct term for identical twins is MONOZYGOT. Monozygotic twins form from a single (mono) fertilized egg. The zygote splits into two parts after conception, resulting in the development of two individual embryos. Because the two embryos are the result of a single egg,sperm combination, they have the same genetic,They have the same DNA.

DIZIGOTIC twins often referred to as fraternal, are the result of two eggs fertilized by two separate sperm. Although most women only have a single egg in an ovulation cycle, sometimes multiples eggs are released. Dizygotic twins share about 50% of their genetic traits, the same as any other siblings born at different times.

SOME INTERESTING THINGS ABAUT IDENTICAL TWINS:

• The causes  of monozygotic twinning are unknown and unidentified. No one really knows why an egg splits; technicaly it's a malfunction of the normal development procces.
• There's no hereditary trait that influences a predisposition to having identical twins. Identical twins is not genetical. Although there are families with a high incidence of identical twins, it is due to chance, coincidence or good luck.
• Despite their shared genetic set, identical twins are unique individual. No two individuals are exactly like.
• Do identical twins always share a placenta during pregnancy?No, this is a myth. Even many doctors will mistake identify twins as fraternal because there are two placentas. It depends on when the egg splits. If it is early enough, the two embryos will implant separately in the uterus and develop individual placentas. If the split occurs later, they may share a placenta.

• Identical twins represent about a third of all twins. Dizygotic twins are twice as common as monozygotic.
• Birth rate statistics for identical twinning have remained stable over the years, despite the overall increase in twins and multiples since the late 1980's. The odds of having identical twins is about 3 in 1,000, whereas the birth rate for all twins is about 32.2 in 1,000.
• Identical twinning is not generally influenced by fertility-enhancing treatments like drugs or in vitro, although monozygotic twins have been produced in pregnancies that were the result of such treatments.
• Birth rates for identical twins are consistent across populations; it is the same regardless of race, geography or maternal age.
• Twins talk with a particular language, baby talk, "idioglossia",  the phenomenon of twin language, a fascinating concept that has intrigued researchers and parents.

I also recommend to read the article in the Times Magazine "Mission Twinpossible": the kelly twins- one in orbit and one on earth- may help NASA unlock the secret of long-term space travel.

How the twins have made?

This happends when 1 oval separated and become to be two

They are identical or not?

They are identical but only in the autside ,inside they are diferent ,one like pizza and the other hatted one loves romance storys and the other action storys 

Im going to put a video to showed.

It is the same identiccal twins that twins?

No.it is completely diferent. identical twins borns from 1 oval and twins are two ovals that fertilisation at the same time.

Whats happends if the oval don´t separated well?

That they will be siamens. It is two persons but with one part of the body together.

hello,now i'm going to talk about twins.

identical twins:
twins happen when breach of fertilized egg divides into two separate babies.Each twin has her or his own differces about physical and personality.The two halves are genetically identical. Identical twins can be one boy and one girl but usually are of the same sex and they share the same DNA.











Fraternal (non identical) twins:

usually happen when two fertilized are implanted in the
uterine wall at the same time that is when the mother releases two eggs and the two together become fertilized by two dissimilar sperms.The two eggs form two zygotes. and these twins therefore in addition  known as dizygotic.

the differces about the identical twins and the fraternal twins are that the indentical twins are nearly identical and the fraternal twins aren't identical.







conjoined (siamese) twins:
they are created exactly like identical twins,but during the split, the 
embryo dosn't disconnected completely to create to disconnected babies the twins develop attached to one another.

TWINS  BY CESAR VILLAR

 

1. THE TWINS ARE TWO PERSONS THAT THEY BORN AS THE SAME TIME.
2. THEY CREATED THE TWINS WHEN MORE THAN ONE SPERM THEY INTRODUCE IN THE OVULE.
3. SOMETIME THE TWINS ARE NOT IDENTICAL.
4. AND SOMETIMES ARE IDENTICAL BUT ARE OPPOSITE SEX.
5. NOT ALWAYS ARE HUMANS ALSO TWINS ARE MONKEYS, ELEFANTS, TIGERS ,LIONS,ETC...
6. USUALLY THE TWINS ARE TWO BOYS OR TWO  GIRLS.

               SOMETIMES, THE TWINS BORN UNITED IN ANY PART OF THE BODY. THEY ARE CALLED SIAMESES. IF THERE AREN´T VITAL ORGANS SHARED, THE DOCTORS CAN SEPARATE THEM.

Rspiratory system

By:Alba Gomez Carrillo
        
 The respiratory system is in charge of breathing:

 When you breath you  do two movements:

• Inhale:the air goes to the lungs.
• Exhale:the air goes out.

PARTS:

1. Nostrils:are two openings un the nose,they filter the air that we breathe.
2. Larynx:conteins the vocal cords,they produce sound.
3. Bronchi:are two branches of the trachea,they take air to the lungs.
4. Diaphragram:is the muscle that creates the movements incloved in breathing.
5. Pharynx:connects the larynx,the oesophagus and the trachea.
6. Trachea:is a tube that takes air into the bronchi.
7. Lungs:are spongy organs made up of small sacs called alveoli

 Hello i´m Alba and in this work i´m going to explain the meaning of twins:

BY:Alba Gomez Carrillo

Characteristics:

• The twins are not identifical twins

• The twins start in one egg

• Some twins can be join because the reproduction not finish

Information: 

Human twins are individuals share the uterus in same pregnancy,

There also quadruplets,quintuples,sextuples,septuples,octuples...he name when they born together:four,five,six,seven,eight....

 The baby of animals an be also twins and triplets



                                                 MONOZYGOTIC TWINS
Are formed only espermatozoide and only egg,also can be derived from a unic zygote

THE TWINS BY JAIME MUÑOZ

hellow,i´m going to talk about the twins(identical and non identical)

identical twins are created when 2 sperm introduce in 1 ovum and then separate in two zygotic

non identical twins are created when 2 sperms introduce in 2 ovums and separate in two zygotic

identical twins are not all identical but are more identical than the non identical twins

the identical twins are almost of the same  sex but there can be a possibility that they are of opposite sexes

the non identical twins can be 50% at the opposite sex and another 50% at the same sex

the identical twins share the same DNA but not are really identical

the non identical twins don´t have the same DNA but they can share some syimilar DNA

some identical twins dont have the two testicles complitely lowered

when one identical twin have an illnes the other is very probably that he is going to have de same illnes mor or les at the same time

in the case of twinsdoes not have to happen

i wish that you liked

thank you for read
