Answer:
Blood must flow to the lungs through the patent ductus arteriosus connecting the aorta and pulmonary artery. Mixing of oxygenated and deoxygenated blood makes a patient's heart inefficient.

Answer:
A. Valves are present between the atrium and ventricles.
Explanation:
There is no mixing of deoxygenated blood and oxygenated blood in the human heart normally because:
1. The human heart has four chambers with two separate chambers for each oxygenated and deoxygenated blood.
2. In order to increase the efficiency of oxygen transport, the mixing of blood is prevented by double circulation.
