Cardiovascular System Anatomy and Function Quiz

The brain is part of the nervous system, not the cardiovascular system.

The left atrium receives oxygenated blood from the lungs before pumping it into the left ventricle.

Capillaries are the smallest blood vessels where exchange of nutrients and oxygen occurs.

The average resting heart rate for adults is typically between 60-70 beats per minute.

The SA node acts as the natural pacemaker, regulating the heart's rhythm.

Smoking is a major factor contributing to the development of atherosclerosis.

The aorta carries oxygenated blood from the heart to the rest of the body.

The SA node initiates electrical impulses, regulating the heart's rhythm.

The vena cava returns deoxygenated blood from the body to the heart.

Blood pressure is the force exerted by blood on the walls of blood vessels.

The aorta carries oxygenated blood from the heart to the entire body.

Veins have valves to prevent the backward flow of blood.

High blood pressure is a significant risk factor for cardiovascular diseases.

The mitral valve prevents backflow from the left ventricle to the left atrium.

A heart attack is medically termed as myocardial infarction.

Irregular heartbeats are characteristic of a condition called arrhythmia.

The relaxation phase of the cardiac cycle is called diastole.
