Cardiac Physiology and Hemodynamics Quiz

Deoxygenated blood from the body enters the right atrium.

During ventricular ejection, the aortic valve opens and blood is ejected into the systemic circulation.

The primary function of the AV node is to conduct electrical impulses to the ventricles.

During isovolumetric contraction, the AV valve closes, preventing backflow into the atria.

Blood pressure is the force exerted by blood against the walls of arteries.

SA node initiates the heartbeat by generating electrical impulses.

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

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

Epinephrine released by adrenal glands increases heart rate and contraction force.

Red blood cells are responsible for oxygen transport to tissues and organs.

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

Afterload is the resistance the heart must overcome to pump blood.

Effusion refers to excess fluid accumulation in the pericardial sac.

The renin-angiotensin-aldosterone system is a key factor in blood pressure regulation.

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs.
