babies start cryn after the muscus has been has been suckd out of d mouth and nostrils, it's probably on very rare cases that the child cries immediately it comes out. I doubt if it even happens

The medical reason as to why they cry is because they need oxygen, ma. Lemme do some Google search and give a link to medical article

trolling: were they deprived of oxygen in the womb if thats the reason why they cry,or in those watersack that they are encased in isnt oxygen an element in water,abeg tell your story to babies me i wan surmise say dem cry because they are being born into a world of trouble

Funny! O'level chemistry is still messing with you. If you think people can survive in water because it contains oxygen, God help you in swimming the Atlantic.

Oh....lol! I get your point now...lol! Yes, of course, positive feedback is needed when the muscles of the myometrium start contracting, that's elementary physiology, Ganong et al. But I didn't know you were talking of relaxation of muscles...lol! I thought you meant that relaxing, as in, not stressing herself by avoiding strenuous tasks during pregnancy is bad, that's why I was surprised...lol! Your point now makes perfect sense to me. Thanks for taking time to explain.

adeaugustus:

Sorry for the typo.

Let me explain the principle of positive feedback mechanism to you...

The body is expected to be in complete homeostasis for you to remain healthy, but this is almost impossible, due to different reasons. So as nature will have it, we have different control system in the body that is responsible for the maintenance of homeostasis. Most of the control system are Negative feedback, i.e. When something is happening somewhere, the body through receptor sends message to the brain and the brain send message back by instructing the process to stop, that's the simple English of negative feedback.


Positive feedback on the other hand is very rare and it may lead to death, the simple English explanation is this: When something unusual is happening and the brain receives signal and instead of instructing it to stop, it instructs the process to continue, example is during child birth and blood clot.

When a pregnant woman is in labour, what happens is that, the womb contracts, and the foetus head hits the cervix, this process continues until delivery. Positive feedback is what helps the womb to contract. This explanation is a bit simple, but it's a complicated medical process that would probably have no meaning to you if you're not in the medical field.

Shey you don get am now? As in why relaxing during child birth no good?

Okies, I'll be glad to see that.

Where or were? SMH.

free2ryhme: where you paid for this publicity stunt

This articles explains why baby cry immediately after birth: It's an anatomical and physiological issue, so you might want to put a medical dictionary beside you... Enjoy.

I don't really need a dictionary for that. Studied anatomy and physiology too and I am in the field myself. I have read the piece, a brilliant one I must say BUT nowhere was it stated that babies cry because they are desperate for oxygen like you stated. Let me quote your source: All of this complicated process is coordinated and controlled by the child’s reflexes; it usually happens within three or four minutes of birth. What makes it happen?

All babies are born soaking wet, and on meeting the atmosphere, the skin cools; this triggers two reflexes:

The cold crying reflex - cold, wet diapers produce the same result, crying.
The cold pressor reflex - cold skin raises blood pressure.
[b]In order to cry, the child must first take a deep breath, and an inspiratory "gasp" is often the first sign, triggered by cold, that a child is going to cry or breathe. Contraction of the diaphragm and intercostal muscles increase thoracic volume and create negative intra-thoracic pressure. Once air is in the lungs, another reflex is triggered that relaxes the pulmonary arterioles; this causes an enormous increase in pulmonary blood flow.

The cold pressor reflex increases the blood pressure in the aorta, and this may be sufficient to reverse blood flow through the ductus arteriosus causing more blood to flow through the lungs.

The cord is also cooling, and the cord is a well-designed self-refrigerator. It has no skin and blubber to keep it warm like the child. It contains only the cord vessels surrounded by a watery gel, Wharton’s jelly, covered by a single layer of cells, the amnion. Water evaporation cools it rapidly, causing the vessels, especially the muscular arteries, to constrict; this further helps to raise systemic blood pressure and to reverse ductus arteriosus flow.[/b] But again, brilliant piece!

Great to know you're in the field too! The part I quote occurs as a result of inspiration right? Which means baby don't cry until they inhale. I might have to do more reading on this before I can start a reasonable argument.

But thanks for "Pushing" me into reading, I will come back to affirm my claim with medical facts.

so how do babies live then in the womb if they dont have any source of oxygen,me i no go medical school but i get common sense,use your logic,that is if you can apply it

No problems at all, it is always mutually beneficial rubbing minds with people like you. Wonderful contributions from your end.

I never said they don't have any source of oxygen, Normally I shouldn't have replied, but you never can tell who is surfing the web for an assignment, better clarification would help such people.

ABOUT THE FOETUS.

It's not a rocket science, and there is nothing called LOGIC when it comes to the issue of life (medicine), studying about the Placenta and the Umblical cord would answer your question on how Foetus are supplied with oxygen and nutrients. You can please read the article on the link above, it will help clarify issue. Thanks.

Yes, you are right. Medicine is not about logic. In fact, often times, things you see are far from logical.

Omoh..will try it out 4 mi first son...I love it!

I have heard of many women that have done water births. I think that the best part of this is doing it in your own home. The atmosphere of being at home is probably much more soothing than a hospital.
