Question

Match each labelled structure to its respective function.​

Answer 1

The table including the correct match is attached in the image:

The tricuspid valve is a three-flapped valve that is located between the right atrium and the right ventricle. It prevents blood from flowing backwards from the right ventricle into the right atrium.

The mitral valve is a two-flapped valve that is located between the left atrium and the left ventricle. It prevents blood from flowing backwards from the left ventricle into the left atrium.

The superior vena cava is a large vein that brings deoxygenated blood from the upper parts of the body to the right atrium.

The pulmonary veins are the only veins in the body that carry oxygenated blood. They carry blood from the lungs to the left atrium.

The inferior vena cava is a large vein that brings deoxygenated blood from the lower parts of the body to the right atrium.

Answer 2

1. Tricuspid valve

2. Mitrial valve

3. superior vena cava

4. Pulmunary veins

5. inferior vena cava

Step-by-step explanation:

1. The three flapped tricuspid valve is located between the right atrium and the right ventricle and prevents backflow and mixing of blood.

2. Mitrial valve is placed between left atrium and left ventricle. Its function is to prevent mixing of blood.

3. Its function is to bring deoxygenated blood to the right atrium.

4. Pulmonary veins are responsible for carrying oxygenated blood from the lungs to the heart it is an exception to veins which always carry deoxygenated blood.

5. The inferior vena cava returns the deoxygenated blood from the parts below the diaphragm to the heart.
