Cardiovascular Physiology and Heart Failure Quiz

Regular exercise is not a risk factor; it's protective against heart failure.

The primary role of the cardiovascular system is to deliver oxygen to body tissues.

Heart failure results from the heart's inability to pump blood effectively.

Pulmonary edema is fluid buildup in the lungs, commonly seen in heart failure patients.

Obesity is a risk factor for heart failure and is modifiable.

Orthopnea, difficulty breathing while lying flat, is a common symptom of heart failure.

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

Diastole refers to the heart's relaxation phase.

Aldosterone plays a primary role in regulating blood pressure and volume.

Cardiac output refers to the volume of blood pumped out by each ventricle per minute.

Coronary artery disease is a primary cause of left-sided heart failure.

Beta-blockers are frequently used to manage symptoms and enhance survival in heart failure.

Heart failure is marked by impaired heart muscle function.

Impaired diastolic relaxation contributes to heart failure with preserved ejection fraction.

Atrial fibrillation is an irregular and rapid heartbeat often observed in severe heart failure.
