Cardiovascular System and Hemodynamic Physiology Quiz

Kidneys are part of the renal system, not the cardiovascular system.

Average resting heart rate for adults typically ranges from 70 to 80 beats per minute.

Regular exercise is typically associated with a decreased risk of cardiovascular disease.

Blood pressure is the pressure exerted by circulating blood against the walls of blood vessels.

The left atrium receives oxygen-rich blood from the lungs, which is then pumped into the left ventricle.

Arteries carry oxygen-rich blood away from the heart to various parts of the body.

Cardiac output refers to the volume of blood pumped by the heart in one minute, typically measured in liters per minute.

One of the primary functions of the cardiovascular system is to transport nutrients and oxygen to cells.

Diastole is the relaxation phase of the cardiac cycle when the heart chambers fill with blood.

The mitral valve, also known as the bicuspid valve, prevents the backflow of blood from the left ventricle into the left atrium.

The Frank-Starling mechanism is a mechanism by which the heart adjusts its output in response to changes in venous return.

Hypertension, or high blood pressure, significantly increases the risk of heart disease and stroke.

Enzymes are not a major component of blood; they are biological catalysts involved in various metabolic processes.

Arrhythmia is a condition characterized by an irregular heartbeat, which may be too fast, too slow, or irregular.

Obesity is a significant risk factor for developing congestive heart failure, a condition where the heart becomes weak and cannot pump blood efficiently.
