Cardiovascular Physiology and Pathophysiology Quiz

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

The heart's primary role is pumping blood to supply oxygen and nutrients throughout the body.

The left ventricle is responsible for pumping oxygenated blood into the systemic circulation.

Systole is the phase when the heart muscle contracts and pumps blood.

Cardiac output is the volume of blood ejected by the heart per minute.

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

Epinephrine, or adrenaline, stimulates the heart, increasing rate and force of contractions.

The sinoatrial node is a cluster of cells regulating the heart's rhythmic contractions.

Atherosclerosis is the condition marked by arterial plaque formation, causing narrowing.

Obesity is a risk factor for hypertension, increasing the strain on the cardiovascular system.

Thrombosis is the process of clot formation within blood vessels.

Peripheral edema, or swelling, is a common symptom of congestive heart failure.

Regular exercise is a protective factor against coronary artery disease, not a risk factor.

Myocardial infarction, or heart attack, occurs due to prolonged oxygen deprivation leading to heart muscle death.
