What is the advantage of four chambered heart? |
|
Answer» 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. 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. |
