On which chamber of the heart does blood flows before going to the lungs?
A
right atrium
B
left ventricle
C
left atrium
D
right ventricle
Explanation: 

Detailed explanation-1: -The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs. Your lungs add oxygen to your blood.

Detailed explanation-2: -When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs. In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.

Detailed explanation-3: -The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

Detailed explanation-4: -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. The left ventricle pumps the oxygen-rich blood to the body.
