Detailed explanation-1: -Birds and mammals, however, have a fully septated ventricle–a bona fide four-chambered heart. This configuration ensures the separation of low-pressure circulation to the lungs, and high-pressure pumping into the rest of the body.

Detailed explanation-2: -Mammals and birds, for example, have four-chambered hearts, with two ventricles and two atria. Frog, crocodile, ostrich, pigeon, bat, and whale all have four chambers in their hearts.

Detailed explanation-3: -The human heart consists of four chambers – two atria and two ventricles – that expand and contract in order to drive blood containing oxygen and nutrients throughout the body.

Detailed explanation-4: -The four‐chambered heart permits the formation of high‐pressure systemic and low‐pressure pulmonary circulation in birds and mammals, allowing for high metabolic rates and maintenance of body temperature.

Detailed explanation-5: -The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. More items
