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

Which vessel does the right ventricle empty into?

A	pulmonary artery
B	pulmonary vein
C	aorta
D	coronary artery

Explanation:

Detailed explanation-1: -Your main pulmonary artery (pulmonary trunk) leaves your right ventricle at your pulmonary valve. It soon splits into your right and left pulmonary arteries, which carry blood to each of your lungs.

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 pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.

Detailed explanation-4: -The right atrium receives deoxygenated blood from the superior vena cava (SVC), the inferior vena cava (IVC), the coronary sinus (covered by the Thebesian valve), and the Thebesian veins.
