Anatomy of the Cardiovascular System Quiz

Heart's main role in circulating blood throughout the body.

Arteries transport oxygenated blood from the heart to tissues.

Capillaries facilitate exchange of gases and nutrients between blood and tissues.

Smoking increases the risk of heart disease and stroke.

Chronic elevation of blood pressure, a significant cardiovascular risk factor.

System responsible for delivering oxygen and nutrients to tissues.

Valves maintain unidirectional blood flow, preventing regurgitation.

The right atrium receives deoxygenated blood from the body.

Pulmonary vein carries oxygenated blood from lungs to heart.

Red blood cells contain hemoglobin, carrying oxygen.

Inferior vena cava returns deoxygenated blood from the lower body to the heart.

Pericardium encloses and lubricates the heart, preventing friction.

Middle layer of the heart, composed of muscle tissue responsible for contraction.

Valves between atria and ventricles prevent backflow, ensuring unidirectional blood flow.

The left ventricle pumps oxygen-rich blood to the body.

Pulmonary vein carries oxygen-rich blood from the lungs to the heart.

Branch of the autonomic nervous system regulating heart rate and blood vessel tone.

Heart's relaxation phase, allowing blood to flow into chambers.

Purkinje fibers spread electrical signals, initiating ventricular contraction.

Heart muscle damage due to blocked blood flow.

Amount of blood ejected from the heart in a minute.

Critical artery supplying blood to large areas of the heart.

Hormone released by heart in response to high blood pressure, promoting sodium and water excretion.

Inflammation of heart's inner lining, often due to infection.

Buildup of plaque in arteries, leading to reduced blood flow.
