Question

Match the cardiac components in the left column to the blanks near their functions on the right.

Answer 1

The human heart consists of four chambers: the right atrium, left atrium, right ventricle, and left ventricle. Each chamber has a specific function in the circulation of blood. The right atrium receives deoxygenated blood from the body, while the right ventricle pumps this blood to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs, and the left ventricle pumps this blood to the rest of the body. Understanding the anatomy and function of the cardiac components is crucial to comprehending the circulatory system.

Step-by-step explanation:

Heart Anatomy and Function

1. Right atrium: Receives deoxygenated blood from the body through the inferior vena cava.
2. Left atrium: Receives oxygenated blood from the lungs through the pulmonary veins.
3. Right ventricle: Pumps deoxygenated blood to the lungs through the pulmonary artery.
4. Left ventricle: Pumps oxygenated blood to the rest of the body through the aorta.

Cardiac Components and Functions

1. Right atrium: Receives deoxygenated blood from the body.
2. Inferior vena cava: Carries deoxygenated blood from the lower body to the right atrium.
3. Coronary sinus: Collects deoxygenated blood from the heart muscle.
4. Right ventricle: Pumps deoxygenated blood to the lungs.
5. Small cardiac vein: Drains deoxygenated blood from the right atrium and ventricle.
6. Right coronary artery: Supplies oxygenated blood to the heart muscle.
7. Posterior interventricular artery: Supplies oxygenated blood to the back of the heart.
8. Middle cardiac vein: Drains deoxygenated blood from the heart muscle.
