Heart Anatomy Flashcard

Front

What is the function of valves in the heart?

Back

Valves prevent the backflow of blood, ensuring it flows in one direction through the heart.

Front

What is the aortic arch?

Back

The aortic arch is the part of the aorta that bends between the ascending and descending aorta, supplying blood to the head, neck, and arms.

Front

Which valve is known as the aortic semilunar valve?

Back

The aortic semilunar valve is located between the left ventricle and the aorta, preventing backflow into the ventricle.

Front

What is the systemic circuit?

Back

The systemic circuit is the pathway that delivers oxygenated blood from the heart to the body and returns deoxygenated blood back to the heart.

Front

What happens if the bicuspid valve fails?

Back

If the bicuspid (mitral) valve fails, it can cause backflow of blood into the left atrium, leading to various complications.

Front

What are the main components of heart anatomy?

Back

The main components include the atria, ventricles, valves, and major blood vessels (aorta, pulmonary arteries, vena cava).

Front

What is the role of the pulmonary arteries?

Back

The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs for oxygenation.

Front

What is the difference between the pulmonary and systemic circuits?

Back

The pulmonary circuit carries blood to the lungs for oxygenation, while the systemic circuit delivers oxygenated blood to the rest of the body.

Front

What is the function 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 significance of the vena cava?

Back

The vena cava are large veins that carry deoxygenated blood from the body back to the right atrium of the heart.
