Build confidence in the foundations of cardiovascular physiology with this introductory quiz. Explore the primary role of the cardiovascular system, the chambers and valves of the heart, and the pathways that move oxygenated and deoxygenated blood. Questions also cover arteries, red blood cells, systole, normal adult resting heart rate, autonomic control of heart rate, pacemaker cells, and the structures that separate the two sides of the heart. Ideal for students beginning anatomy and physiology, biology, nursing, or other health science coursework.

The primary function of the cardiovascular system is the transport of nutrients, gases, and waste products to and from cells.
The left ventricle pumps oxygenated blood into the aorta and throughout the body.
Arteries are blood vessels that carry blood away from the heart.
Red blood cells contain hemoglobin and are primarily responsible for the transport of oxygen.
Systole is the phase of the heart cycle during which the heart muscles contract and pump blood out.
The mitral valve prevents backflow of blood from the left ventricle into the left atrium.
The normal resting heart rate for adults is 60-100 beats per minute.
The sympathetic nervous system increases the heart rate during stress or physical activity.
Pacemaker cells are responsible for generating and regulating the heart's rhythm.
The septum is a structure that separates the heart's right and left sides, preventing the mixing of oxygenated and deoxygenated blood.
