Anatomy of the Heart

The two superior receiving chambers pf the heart are known as the

• ventricles

• atria

• arteries

• veins

The two inferior discharging chambers of the heart are known as the

• ventricles

• atria

• arteries

• veins

The transportation of blood from the right side of the heart to the lungs and back to the left side of the heart is known as ______________ circulation.

• systemic

• cardiac

• coronary

• pulmonary

What are the tiny white cords that anchor the cusps or flaps of endocardium to the walls of the ventricles?

• chordae tendineae

• ligamentum arteriosum

• ductus venosus

• myocardium

What large blood vessels carry blood away from the heart?

• arteries

• capillaries

• veins

• venae cavae

What structure divides the left ventricle from the right ventricle?

• bicuspid valve

• interventricular septum

• semilunar valve

The heart is situated within the medial section of the _____________ cavity.

• cranial

• abdominal

• pelvic

• thoracic

Which of the following correctly list the walls of the heart in order from innermost to outermost?

• epicardium, myocardium, endocardium

• endocardium, myocardium, epicardium

• left atrium, left ventricle, right atrium, right ventricle

• left AV valve, semilunar valve, right AV valve, aortic semilunar valve

Inflammation of the pericardium that often results in a decrease in the already small amount of pericardial fluid is known as

• pericarditis

• heart murmur

• thrombophlebitis

• varicose veins

What is the function of the valves found in the heart?

• to provide nutrient blood to the heart muscle.

• to actual "pump" the heart.

• to prevent the backflow of blood.

• to add to the lining of the heart chambers to make it stronger.
