Pharmacotherapeutics: Cardiovascular System

These flashcards cover key concepts and vocabulary related to the cardiovascular system as discussed in the lecture.

Pulmonary Circulation

The part of the circulatory system that carries deoxygenated blood from the right side of the heart to the lungs for oxygenation.

Systemic Circulation

The part of the circulatory system that carries oxygenated blood from the left side of the heart to the rest of the body.

Atrioventricular Valves

Valves located between the atria and ventricles of the heart; includes the tricuspid and mitral valves.

Semilunar Valves

Valves located between the ventricles and the arteries; includes the pulmonary and aortic valves.

Myocardium

The muscular middle layer of the heart wall that is responsible for the contraction of the heart.

Pericardium

The fibrous sac surrounding the heart, consisting of an outer fibrous layer and an inner serous layer.

Cardiac Cycle

The sequence of events that occurs during one heartbeat, including the contraction and relaxation of the heart chambers.

Systole

The phase of the cardiac cycle when the heart muscle contracts and pumps blood from the chambers into the arteries.

Diastole

The phase of the cardiac cycle when the heart muscle relaxes and the chambers fill with blood.

Cardiac Action Potentials

Electrical impulses that initiate the contraction of the heart muscle.
