  1. Right atrium and right ventricle
  2. Left atrium and left ventricle
  3. Pulmonary artery and pulmonary veins
  4. Aorta and vena cava

A
Right atrium and right ventricle
B
Aorta and vena cava
C
Left atrium and left ventricle
D
Pulmonary artery and pulmonary veins
Solution
Verified by Toppr

The correct pathway is: Vena cava Right atrium Right ventricle Pulmonary artery Lungs Pulmonary veins Left atrium Left ventricle Aorta Rest of the body.
Aorta is the main artery that carries oxygenated blood from the left ventricle of the heart towards the other parts of the body.
Vena cava collects deoxygenated blood from the body and pours the blood into the right atrium.
So, the correct answer is option D.

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.

Q5
Assertion :Pulmonary circulation consists of flow of deoxygenated blood from right ventricle to the lungs and flow of oxygenated blood from lungs to the left atrium. Reason: Systemic circulation consists of flow of oxygenated blood from the left ventricle to all parts of the body and deoxygenated blood from different parts to right atrium.
