Cardiovascular System

From right to left the three branches of the aorta are:

• Brachiocephalic trunk, Left common carotid artery, Left subclavian artery

• Brachiocephalic vein, Left common carotid vein, Left subclavian vein

• Left subclavian vein, Left common carotid artery, Brachiocephalic trunk

• Brachial artery, Bacilic artery, Cephalic artery

Oxygenated blood returns to the heart via the:

• Pulmonary arteries

• Superior vena cava

• Pulmonary veins

• Aorta

What is the function of the semilunar valves?

• Control heart rate

• Prevent backflow of blood into the left ventricle

• Prevent backflow of blood into the right ventricle

• Filter impurities from the blood

The highlighted structures are the:

• Chordae Tendineae

• Tendineae chordae

• Tricuspid valve

• Right atrium

The highlighted structures are

• Papillary muscles

• Pulmonary semilunar valve

• Chordae tendineae

• Pulmonary veins

The superior vena cava and inferior vena cava:

• Bring deoxygenated blood to the heart from the rest of the body

• Bring oxygenated blood to the heart from the rest of the body

• Bring oxygenated blood to the heart from the lungs

• Bring deoxygenated blood to the heart from the lungs
