Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following blood flow statements is true?
A
Blood is pumped by the right atrium through the mitral valve into the right ventricle
B
Blood is pumped by the right atrium into the right ventricle to the pulmonary trunk toward the lungs
C
Blood is pumped by the left ventricle through the mitral valve into the aorta
D
Blood flows from the pulmonary capillaries to the pulmonary arteries to the left atrium
Explanation: 

Detailed explanation-1: -Blood flows from the right atrium into the right ventricle through the tricuspid valve. When the ventricle is full, the tricuspid valve shuts to prevent blood flowing backwards into the atrium. Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs.

Detailed explanation-2: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.
