Solution

The correct option is D Oxygenated blood is pumped into the aorta and deoxygenated blood is pumped into the pulmonary artery
Due to contraction of the ventricles (ventricular systole), the pressure inside the ventricles rises that forces to open the semilunar valves of aorta and pulmonary artery so that the blood enters into these vessels. Oxygenated blood is pumped into the aorta from the left ventricle while deoxygenated blood is pumped into the pulmonary artery from the right ventricle.

Q. Read the statements and select the option which best describes the process that occurs during systematic circulation.
(i) The left atrium receives the oxygenated blood through the pulmonary veins. The left ventricle pumps the blood through the aorta to various parts and the de-oxygenated blood reaches right atrium.
(ii) The left atrium receives the oxygenated blood through pulmonary veins and pumps the blood through the aorta to various parts and the de-oxygenated blood reaches the right atrium.
(iii) The left atrium receives de-oxygenated blood and pumps into left ventricles which in turn pumps into pulmonary artery for oxygenation.
(iv) The right atrium receives the de-oxygenated blood and pumps into pulmonary artery for oxygenation.
