Fill in the Blanks

Multiple Choice

TYPE of blood flow that cycles from the right ventricle to the lungs and back to the left atrium

• systemic circulation
• pulmonary circulation

Multiple Choice

TYPE of blood flow that cycles to the body tissues; allows for oxygen to be distributed to all the cells of the body.

• systemic circulation
• pulmonary circulation

Multiple Choice

What vessels carry deoxygenated blood away from the heart?

• Neither coronary arteries or pulmonary artery

• Pulmonary artery only

• Both coronary arteries and pulmonary artery

• Coronary arteries only

Multiple Choice

The epicardium is the same thing as the

• parietal pericardium

• fibrous pericardium

• pericardial cavity

• visceral pericardium

• endocardium

Multiple Choice

The purpose of the pericaridal cavity filled with serous fluid is

• to prevent damage to the heart tissue caused by friction

• to allow nutrients and oxygen to bathe the heart

• to allow waste removal from cardiac muscle

• to prevent damage to the heart tissue by removing excess fluid from heart tissue

Multiple Choice

What are heart valves?

• Sections of the heart that divide up the individual chambers.

• Flaps of heart tissue that only allow blood to flow in one direction

• Fibers within the heart that create the cardio-electric rhythm required for synchronized beating

• Openings within the heart that allow blood to enter and leave the heart. One is the Vena cava, the other is the Aorta.

Multiple Choice

Which of the following valves are considered to be AV valves?

• pulmonary valves

• aortic valves

• semilunar valves

• tricuspid & mitral valves

Multiple Choice

What holds the cusps of valves within the heart in place?

• Chordae Tendineae

• Purkinje Fibers

• The Septum

• Nothing - the valves are connected directly to the heart tissue.

Match

Match the heart valves with their function

• allows blood to leave the L. ventricle and enter the aorta

• allows blood to leave the R. ventricle and enter the pulmonary trunk

• allows blood to leave the R. atrium and enter the R. ventricle
