Answer:
I HOPE THIS WILL HELP YOU
Explanation:
In animals and birds :-
Double circulation pathways are found in birds and mammals. Animals with this type of circulatory system have a four-chambered heart. The right atrium receives deoxygenated from the body and the right ventricle sends it to the lungs to be oxygenated.
In human beings :-
The left ventricle pumps oxygenated blood into aorta for systematic circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.
Answer:
Explanation:
animal like mamals and etc are warm blooded animals.they need a warm temp to survive. and when the blood flow continuously then only a constant temp is maintained, and also they need lot of energy .so when the blood flows continuously then lot and lot of energy is being created. and so beacause of this the animal need to have 4 chambers.so that the oxygenated and deoxygenated blood is seperated
