Flashcard on Human Heart Anatomy

Front

What is the epicardium?

Back

The epicardium is the outer layer of the heart, also known as the visceral layer of the serous pericardium.

Front

Where is the point of maximal intensity (PMI) located in the heart?

Back

The PMI is located at the apex of the heart, which is the pointed end of the heart.

Front

What type of tissue makes up the myocardium?

Back

The myocardium is primarily composed of cardiac muscle tissue, which is responsible for the heart's contraction.

Front

What is the function of the tricuspid valve?

Back

The tricuspid valve prevents the backflow of blood from the right ventricle into the right atrium.

Front

What is the main function of the left ventricle?

Back

The main function of the left ventricle is to propel oxygenated blood through the aorta to the rest of the body.

Front

What are the four chambers of the heart?

Back

The four chambers of the heart are the right atrium, right ventricle, left atrium, and left ventricle.

Front

What is the role of the aorta in the circulatory system?

Back

The aorta is the main artery that carries oxygenated blood from the left ventricle to the body.

Front

What is the function of the pulmonary valve?

Back

The pulmonary valve prevents backflow of blood from the pulmonary artery into the right ventricle.

Front

What is the significance of the septum in the heart?

Back

The septum is a wall that separates the left and right sides of the heart, preventing the mixing of oxygenated and deoxygenated blood.

Front

What is the role of the coronary arteries?

Back

The coronary arteries supply blood to the heart muscle itself, providing it with oxygen and nutrients.
