Why heart is completely divided into four chambers? |
|
Answer» because in human body it is necesaary to seperate the oxygenated and deoxygenated blood from mixing... also it is known as double blood circulation because the blood FLOWS twice through the heart in one circulation.. there are four chamber —left auricle,left ventricle ,right auricle and right ventricle.. it is DIVIDED by a layer called septa... in some organism like fishes have two chambered hearts because blood directly flows from gills to body then heart |
