Cardiovascular System - Anatomy & Blood Flow

Front

What are heart murmurs?

Back

Abnormal or unusual heart sounds often indicative of underlying heart conditions.

Front

What do the anterior and posterior interventricular sulci mark in the heart?

Back

They mark the location of the interventricular septum inside the heart.

Front

List the four sets of valves in the heart.

Back

1. Bicuspid (Mitral) Valve 2. Tricuspid Valve 3. Pulmonary Semilunar Valve 4. Aortic Semilunar Valve

Front

In what order does blood flow through the heart valves starting from the right atrium?

Back

2 (Tricuspid), 3 (Pulmonary Semilunar), 1 (Bicuspid), 4 (Aortic Semilunar).

Front

True or False: Chordae tendineae assist the cusps of the semilunar valves in preventing back flow of blood.

Back

False. Chordae tendineae are associated with atrioventricular valves.

Front

What is the apex of the heart?

Back

The apex is the pointed end of the heart, located inferiorly and anteriorly.

Front

What is the base of the heart?

Back

The base is the broad, upper part of the heart where major blood vessels enter and exit.

Front

What is the function of the interventricular septum?

Back

It separates the left and right ventricles of the heart.

Front

What is the role of the tricuspid valve?

Back

It prevents backflow of blood from the right ventricle to the right atrium.

Front

What is the significance of the pulmonary semilunar valve?

Back

It allows blood to flow from the right ventricle into the pulmonary artery while preventing backflow.
