Basic Heart Anatomy and Function

Front

What is the primary function of the heart?

Back

The primary function of the heart is to pump blood throughout the body, supplying oxygen and nutrients to tissues and removing carbon dioxide and other wastes.

Front

What are the four chambers of the heart?

Back

The heart has four chambers: two upper chambers called atria (right atrium and left atrium) and two lower chambers called ventricles (right ventricle and left ventricle).

Front

What separates the left and right sides of the heart?

Back

The septum is a wall of tissue that separates the left and right sides of the heart.

Front

What is the role of the atria in the heart?

Back

The atria receive blood returning to the heart from the body and lungs and pump it into the ventricles.

Front

What is the role of the ventricles in the heart?

Back

The ventricles pump blood out of the heart to the lungs and the rest of the body.

Front

What are the major blood vessels connected to the heart?

Back

The major blood vessels connected to the heart include the aorta, pulmonary arteries, pulmonary veins, and the superior and inferior vena cavae.

Front

What is the function of the heart valves?

Back

Heart valves ensure one-way blood flow through the heart, preventing backflow. They include the mitral, tricuspid, aortic, and pulmonary valves.

Front

How does the heart receive oxygen and nutrients?

Back

The heart receives oxygen and nutrients through the coronary arteries, which branch off from the aorta.

Front

True or False: All arteries carry oxygen rich blood

Back

False

Pulmonary Arteries carry oxygen poor blood to the lungs for oxygenation

Front

How does the heart regulate its own blood supply?

Back

The heart regulates its own blood supply through the coronary circulation, which adjusts based on the heart's oxygen and nutrient needs.
