Chapter 11: The Cardiovascular System

The pointed apex of the heart is oriented toward the

• umbilicus

• left hip

• left shoulder

• right hip

• right shoulder

The layer of the heart wall synonymous with the visceral layer of the serous pericardium is

• epicardium

• myocardium

• either endocardium or epicardium

• endocardium

• parietal layer of the serous pericardium

Pulmonary circulation involves blood flow to and from the heart and the

• body

• brain

• skin

• digestive organs

• lungs

The right AV valve is known as teh

• tricuspid valve

• mitral valve

• aortic semilunar valve

• bicuspid valve

• pulmonary semilunar valve

Pulmonary veins

• return blood to the right atrium of the heart

• transport blood rich in carbon dioxide to the lungs

• transport oxygenated blood to the heart

• transport oxygenated blood to the lungs

• split off the pulmonary trunk

What structure divides the left from the right ventricle?

• tricuspid valve

• interventricular septum

• bicuspid valve

• interatrial septum

• chordae tendineae

When the ventricles contract, the bicuspid (mitral) valve prevents blood from flowing from the

• left ventricle to the right ventricle

• right ventricle to the right atrium

• left atrium to the right atrium

• left ventricle to the left atrium

• right atrium to the left atrium

The tricuspid valve is located between the

• right atrium and right ventricle

• left ventricle and pulmonary artery

• left ventricle and aorta

• right ventricle and the pulmonary trunk

• right atriums and left atrium

Deoxygenated blood is returned to the right side of the heart by the

• superior and inferior vena cavae

• pulmonary arteries

• pulmonary trunk

• pulmonary veins

• aorta

Which one of the following blood vessels carries oxygenated blood?

• coronary sinus

• pulmonary artery

• pulmonary vein

• inferior vena cava

• superior vena cava
