Cardiovascular system (heart)

What are the top two chambers of the heart?

• Atria

• Ventricles

• artery

• pericardium

What is the main function of the heart?

• to force water out of the body

• to carry carbon dioxide to every cell.

• to pump blood throughout the body, carrying oxygen and nutrients to every cell.

• to pump white blood cells throughout the body to neutralize t-cells

How many chambers are in the heart?

• 3

• 7

• 5

• 4

A period of relaxation is called

• AV valves

• Diastole

• Systole

• Relaxation

Which series depicts the correct order that the blood flows through the heart?

• inferior and superior vena cava, left atrium, left ventricle, right atrium, right ventricle, body, lungs

• body, left atrium, right atrium, left ventricle, lungs, right ventricle, aorta artery, inferior and superior vena cava

• right atrium, right ventricle, left atrium, left ventricle, lungs, aorta artery, body

• inferior and superior vena cava, right atrium, right ventricle, lungs, left atrium, left ventricle, aorta artery, body

Which of the following would increase blood pressure?

• Constricted blood vessels

• Low heart rate

• Dilated blood vessels

• Low blood volume

A drug that constricts blood vessels would have which of the following effects?

• Decrease heart rate

• Increase blood pressure

• Decrease blood pressure

• Increase heart rate

What is the largest artery in the body?

• Systole

• Ventricle

• Atria

• Aorta

What effect would constriction of the blood vessels have on the body?

• Increased blood volume resulting in decreased heart rate

• Increased blood pressure resulting in risk of heart attack

• Decreased blood pressure resulting in light headedness

• Decreased blood volume resulting in decreased heart rate

Which of the following would occur if the heart pumped more strongly with each beat?

• decrease in both systolic and diastolic pressure

• decrease in systolic but increase in diastolic pressure

• Increase in systolic but decrease in diastolic pressure

• Increase in both systolic and diastolic pressure
