Anatomy and Physiology of Cardiovascular System Quiz

The kidneys are part of the urinary system, not the cardiovascular system.

The left atrium receives oxygenated blood from the lungs before pumping it to the rest of the body.

Regular exercise is a protective factor, not a risk, for cardiovascular diseases.

The pulmonary vein transports oxygenated blood from the lungs to the heart.

Arteries transport oxygenated blood away from the heart to various tissues and organs.

The mitral valve ensures one-way flow, preventing blood from flowing back into the left atrium.

The sinoatrial node generates electrical impulses, regulating the heart's rhythm and acting as the pacemaker.

Epinephrine, released during stress, elevates heart rate and blood pressure.

Capillaries are tiny vessels facilitating the exchange of nutrients and oxygen between blood and tissues.

Systole is the phase when the heart contracts, pumping blood into the circulatory system.

Myocardial infarction refers to the condition where blood flow to a part of the heart is blocked, causing damage.

Cardiac output measures the amount of blood pumped by each ventricle in one minute.

Diastole is the phase when the heart relaxes and fills with blood before the next contraction.

Coronary thrombosis occurs when there's a blockage in the coronary arteries, limiting blood flow to the heart muscle.
