Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which path describes the movement of oxygenated blood?

A	Vena cava to right atrium to right ventricle
B	Pulmonary vein to left atrium to left ventricle
C	Right ventricle to pulmonary artery to lungs
D	None of the above

Explanation:

Detailed explanation-1: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

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 left coronary artery delivers blood to the left side of your heart, including your left atrium and ventricle and the septum between the ventricles. The circumflex artery branches off from the left coronary artery to supply blood to part of the left ventricle.
