When the muscles of the heart relax
-
Blood flows from lungs into the left auricle

-
Blood flows from the left ventricle to the rest of the body
When the muscles of the heart relax, the right atrium receives deoxygenated blood from all parts of the body through superior, inferior vena cava and coronary sinus. The left atrium receives oxygenated blood from the lungs through two pairs of pulmonary veins. Thus option C is the correct answer.
Blood from the left ventricle is pumped to
-
Lungs
-
Left auricle
-
Right ventricle
-
All parts of the body
The left ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.

-
Heart
-
Kidneys
-
Small intestine
-
Stomach
The serosal pericardium is a closed sac within the fibrous pericardium. It consists of two layers. The visceral layer, called the epicardium, covers the heart and great vessels and is reflected back onto the parietal layer, which lines the interior of the fibrous pericardium.
