Question

WHY IS IT NECESSARY TO SEPARATE OXYGENATED AND DEOXYGENATED BLOOD IN MAMMALS AND BIRDS?

Answer 1

Mammals and birds are animals which can be called warm-blooded animals.

Warm-blooded animals have the characteristic that they can produce body heat, even if it is cold outside.

It is necessary that the oxygenated and Deoxygenated blood is separated so that the body does not generate excessive heat due to excessive production of carbon dioxide.

Answer 2

Answer:

• It is necessary to separate oxygenated and deoxygenated blood in mammals and birds because they are warm-blooded animals, animals that maintain constant body temperature despite external conditions. They need to maintain the homeostasis.
• A separate oxygenated and deoxygenated blood system is very important for the efficient circulatory system and transport more oxygen to the needed cells. More oxygen transport to the required cells and they produce energy which is later used to maintain the life processes such as homeostasis.
• The hearts of both mammals and birds are designed in such a way that they separate oxygenated and deoxygenated blood. It is 4 chambered, consisting of two atriums and two ventricles. Blood enters the heart via the right atrium and then goes to the right ventricle. Right ventricle transports this deoxygenated blood to lungs for purification. Purified blood from lungs comes back to the heart in the left atrium and then goes to left ventricle which transports oxygenated blood to the whole body.
