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.

                                
                                TWINS
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 ?
