CIRCULATORY SYSTEM

The circulatory system is very important for our body.
His function is to transport blood in all our body.
The human heart is an organ that pumps blood throughout the body via circulatory system.

The heart is a very important part of the circulatory system.

The circulatory system is an organ that permits blood to circulate and transport lots of nutrients like oxygen, carbon dioxide, hormones...

Is very important to clean the blood circulating through the body.

Here you can see how the blood go through all the body.

We could not live if we don´t have heart.

THE TWINS

 

 

                                         

     THE TWINS

Hello I´m going to talk about the twins , the twins are two babies that grow in the same gestacion and at the same time they have to be the same sex girls or boys .They come from a singel zygote .It is unclear wy this happens but the egg before starting to divide get more material and mass ,  the experts say that is because one cell could´n process 2 babies .

                                                  

 

 How identical twins grow?

The cell grow like a normal baby but after  the cell divides into two cells this process takes 12 or 13 days , after that days , the egg may not divide .the experts didn´t have a reason of why the egg spilts and they say that is cause from the nature .The twins share the same DNA but they don´t have an identical DNA they also have the same blood group.

                        

How identical twins are not identical?

There are 2 main reasons of wy identical twins are not identical, wen the cell divides into two parts the two cells are not identical is like wen you cut and apple the two parts are not identical and that is the same with the twins, and the other is that the identical twins doesn´t  have the same character and the same personality.

 

                          

The diferences between twins and identical twins

The diferences between twins and identical twins are that the identical twins grow in the same bag and twins grow separete, each baby in his bag, the cell of the twins is doesn´t separete and then appear two cells .

            

       

Identical twins also can be form in animals , like dogs cats and also identical twins can be 3 babies this is occurs wen insted of 2 babies grow .

         

                              

All things that You have to now about twins

                                HOW ARE IDENTICAL TWINS FORMADE?

🐣THE IDENTICAL TWINS formade when one egg after have being the fertilezed devides into two halves this proces make the twins🐥.   

 👬Normally the twins are genetically identical👬

🌐USUALLY THE TWINS ARE OF THE SAME SEX BUT IN OTHER CASES NOT🌐

           

                                          ARE THE TWINS IDENTICAL?????

  The twins normally are identical but some time not because sometimes one twin is a boy and the other I a girl .There are some cases in which twins leave the egg of his mother glued among them.When that happens normally one of the twins life and the other die or the 2 twins die or the tow twins life.

You can visit this page is the Wikipedia this pages splain the identical twins,placentation...etc

                                               WHAT IS THE PREGNANCY??

          👪The pregnancy is the time after the fertilize that the mum wait for baby's born👪

                                           HOW THE BABY CREATED????

                                                                                              

👀The baby created when the ova and the sperm  join and created a fetus that grow and grow to become a baby👀

                                          WHAT IS THE PLACENTA????

💧The placenta is the organ that connect the mum whith the baby💧

                                   WHAT IS A MONOZYGOTIC???

            Is a developed from a single fertilized ovum,AS IDENTICAL TWINS

Nativity Twins¡¡¡

                                    ALL ABOUT THE TWINS

 Twin pregnancies are special and only occur the 30% of the maximum of possibilities.

The beginning of its development begins as those of single babies, the ova and the sperm come together and form a set of two parts called zygote.That is why the twins are called monozygotic.

This zygote divides to form two separate embryos that are then identical twins.

This event occurs during the first week after fertilization and can occur in phase two cells on day 2, in the early blastocyst stage on day 4 or in the late blastocyst stage on day 6.

If the zygote has been separated more earlier more independent   are going to be.

If the twins are separated in phase two cells, they will form each their own amnion, chorion and placenta.

                                  

                                MINI  DICTIONARY

If you haven't understood any word you can search hear to learn more:

Embryos:Is the beginning of a living thing being in the womb of his mother.

Womb:Where the embryos begins his life.

Blastocyst:Is an embryos that haves 200 cells.

Amnion:It's a membrane that protects the embryos.

Chorion:Is an outer that covers the embryos.

Placenta:It's an organ that connects the baby with the mother.

RESPIRATORY SYSTEM

THE RESPIRATORY SYSTEM

-The respiratory system, performs an action, breathing.
-Breathing performs two types of moments:
-We inhale air and it goes into the lungs.
-We exhale air sending it out of the lungs.

The parts of the respiratory system:
1:the nostrils are two openings in the nose.
2:the larynx contains the vocal cords. 
3:the bronchi are two branches of the trachea.
the diaphragm is the muscle that creates the movements involved in brathing.
4:the pharynx connects the larynx,the oesophagus and the trachea.
5:the tranchea is a tube that takes air into the bronchi.
6:the lungs are the more important organ and there are spongy organs made up of small sacs called alveoli 

twins.

                                                            TWINS  



-How it happends?  

s.Twins hapend wen a  zigote starts to get sparate we now if  is one or two babys when it pases the thelve days after of fregnancy, if it pases 12 day and is´t monothigotic is only one babay ,but if it pases 12 day and it  the cigotic splitis in to two it will be 2 babys or more. Other posibility is that the zigotic stats to splits but not to much and then that means that you will have to babys that one part of the body will be conect. that case hapend one of 200 birhts normaly the division of the fetus .

-Different sex?

it is verry difficult have twins off oposite sex but it can be other posibility that is one of the babys have the sindrom of the turner and in this case one it can be girld and other boy

-How siames do things ?

they have to do all together and with specially help becuse is very difficult , wen you are adecuated tu that routine to them is much easier .

 twins

-When the babys are in the mother belly perfectly it can be two twins and one brother / sister.
-The twins have the same DNA but not the same digital foootmarck in the fingers.
-Now around the world are like 125.000.000 twins.
-They are not many posibilities but whit the invitro fertilizacion are cases of twins with 5 years of diference. 

The respiratory system!!!

THE                                    RESPIRATORY

      SYSTEM

·    The respiratory system is very important because thanks to it you can breathe.

·    If you don’t have the respiratory system you can’t be alive.

·    The parts of the respiratory system are this ones.

·    The nostrils filter the air that we   

breathe.

·    The pharynx connects the oesophagus, the trachea and the larynx.

·    The larynx contains the vocal cords.

·    The trachea is a small tube that takes the air in to the bronchi

·    The bronchi takes air in to the lungs

·    The lungs are two sacs made of alveoli.

·    The respiratory system has two movements.

·    The inhale air and it goes into the lungs.

·    And the exhale air sending out of the lungs .

·    The respiratory system is in charge of breading.

circulatory system

                                            Circulatory  system .  
The  circulatory  system  moves substance 
 around  our  bodies .

•  It  takes  oxygen  to  all  parts  of  the  body.
• It  takes  nutrients  to  all  parts  of  the body.

The  blood  and  the  heart  make  up  the circulatory  system .
                  The  blood 

• Blood  is  a  red  liquid  that  goes  all around  the  body .
•  The  blood  circulates  through  a  tubes    called  blood  vessels . there  are  3  kinds  

-arteries  takes  blood  from  the  heart  to  the  rest  of  the  body  .
-veins  take  blood  from  the  rest  of  the body   to  the  heart .
-capillaries  are  thin  tubes  that  connect arteries  and  veins .
-the  heart  is  the  organ  that  pushes  blood round  the  body.
                      The heart
The  heart  is  an  organ . 
The size of the heart is a fist .
The  heart  it  is  between  the two lungs .
The  heart  receives  and  pushes  out  
 blood  continuosly . 
The heartbeat:
Is  the  sound  of  the  heart  as  it  contracts
and  relaxes .
       Do  you  think  that  is  important  the circulatory  system ?
      Do  you have any questions  ?

respiratory system by: marta labadia

the respiratory system

Hello i´m marta of the class 6 B

I going to talk abaut the respiratory system.

 

the respiratory systemserves to breathe,

the respiratory system have many parts:

nostrils,trachea, pharynx, larynx, lungs, and bronchi.

 

 nostrils: are two opening in the nose.

trachea: is a tuve that takes air into the bronchi.

pharinx: conects the larynx, oesphagus and the trachea.

larynx: they produce sound.

lungs: contains the air.

bronchi: take the air for the lungs.

 

 

the funtion of the lungs.

in this photo you can see the funtion of the lungs.

 

for me the most important part are the lungs,

becouse:

 

the funtion of the lungs in the respiratory system

is very important becouse the lungs

help you to breath.

 

now some questions:

 

1. for you what are the most important part

of the respiratory system?

 

2. for what are important the lungs?

 

3.have you got any questions?

 

 

 

 

 

THE END

                             THE TWINS

The twins they are not the same, 
also us the other person  
they have more than one difference.

They grow inside the same zygote and inside the same estomage.

We use the same name to the persons who are  similar or equal.
whit dogs or cats and more animals, they not use the name twins
because we cant not see much difference in the animals.


 They are meny cases of twins from the person to the animals.
The twins have diferent tastes, feelings,aspects.

But we have specific cases: one of the twins have a health problem,and is possible that the other twin have the same problem, but at different time.

The twins they not have the same fingerprint 
as the other brothers and  the other systers.
SPECIAL INFORMATION
1. An 25 % develop  face to face.

2.This is the cause of the mirror effect.

3.A mum of twins live more years.

4.The tall woman have more chance of having twins.

5.The woman who eat so much dairy, have more chance of have twins.

6.Meny twins invent her own language.
