Vedclass · Answer

(B) In a $4$-chambered heart,the heart is divided into two atria and two ventricles. This complete separation ensures that oxygenated (arterial) blood and deoxygenated (venous) blood do not mix. In contrast,$2$-chambered hearts (found in fish) have a single circulation where blood passes through the heart once,and $3$-chambered hearts (found in amphibians and most reptiles) allow for the mixing of oxygenated and deoxygenated blood in the single ventricle.
