In mammals and birds,why is it necessary to separate oxygenated and deoxygenated blood ?

Question

Answer

Because, this ensure high supply of Oxygen to release more energy and in order to maintain constant body temperature.

Answer

Mammals and birds are warm blooded animals. They constantly use energy to maintain their body temperature. They have higher energy needs and so they require more oxygen to produce energy. Thus, it is important that their oxygenated blood does not get mixed up with the deoxygenated blood.

Answer

Answer

Warm-blooded animals such as birds and mammals maintain a constant body temperature by cooling themselves when they are in a hotter environment and by warming their bodies when they are in a cooler environment. Hence, these animals require more oxygen (O2) for more cellular respiration so that they can produce more energy to maintain their body temperature.Thus, it is necessary for them to separate oxygenated and de-oxygenated blood, so that their circulatory system is more efficient and can maintain their constant body temperature.

Answer

Importance of Separating Oxygenated and Deoxygenated Blood in Mammals and Birds

Efficient Oxygen Delivery: Separation of oxygenated and deoxygenated blood in mammals and birds ensures efficient delivery of oxygen to the tissues.

Double Circulation System: Mammals and birds have a double circulation system, where oxygenated and deoxygenated blood are separated in two different circuits.

Pulmonary Circuit: In mammals and birds, the pulmonary circuit carries deoxygenated blood from the heart to the lungs for oxygenation.

Systemic Circuit: The systemic circuit carries oxygenated blood from the heart to the rest of the body for oxygen delivery.

Prevents Mixing of Blood: Separation of oxygenated and deoxygenated blood prevents the mixing of blood and maintains a concentration gradient for efficient gas exchange.

Higher Metabolic Rate: Mammals and birds have a higher metabolic rate, and separating oxygenated and deoxygenated blood ensures adequate oxygen supply to meet their energy demands.

Adaptation to High Altitudes: Separation of oxygenated and deoxygenated blood is crucial for animals living at high altitudes where the oxygen level is lower, as it helps to maximize oxygen delivery to the tissues.

Efficient Oxygen Uptake: Separating oxygenated and deoxygenated blood helps to maximize oxygen uptake in the lungs, as the concentration gradient is maintained.

Answer

1) High Energy requirements
2) Seperate oxygenated and deoxygenated blood provide required amount of oxygen
3) This oxygen help in conversion of food into energy through respiration
