Write advantages of 4 chambered heart?
Answers
The four-chambered heart has a distinct advantage over simpler structures: It allows us to send our "dirty" blood to the cleaners-the lungs-and our "clean" blood to the rest of the body without having to mix the two. That system is very efficient.
Answer:
Presence of four chambered heart serves two purposes. First, it ensures complete segregation of oxygenated and deoxygenated blood. Second, blood is received by the upper chambers and is pumped out by the lower chambers. This segregation between received blood and sent blood increases the efficiency of the heart.
In four chambered heart left half is completely separated from right half by septa.This prevents oxygenated and deoxygenated blood from mixing This allows a highly efficient supply of oxygenated blood to all parts of the body.This is useful in animals that have high energy needs such as birds and mammals.
