Chambers of Heart

Q.

The mitral valve is present between

1. Right and left ventricles

2. Right atrium and right ventricle

3. Left atrium and left ventricle

4. Left ventricle and aorta

Q. Define of pulmonary circulation.

Q. Systemic circulation is defined as the

1. flow of oxygenated blood from left ventricle to all parts of the body and the return of deoxygenated blood from various body parts to the right atrium
2. flow of deoxygenated blood from the right ventricle to the lungs and the return of oxygenated blood from the lungs to the left atrium
3. flow of deoxygenated blood from the digestive organs to the liver before returning to the heart
4. flow of oxygenated blood from the ascending aorta to the heart muscle and the return of deoxygenated blood from the heart muscle to the right atrium

Q. The inlets of the left atrium is guarded by

1. None of the above
2. Eustachian valve
3. Thebesian valve
4. Mitral valve

Q.

Heart of frog has:

1. 2 atria and 1 ventricle

2. 2 ventricles and 1 atrium

3. 2 ventricles and 2 atria

4. 1 atrium and 1 ventricle

Q. Match the following
$\begin{array}{cc}\text{Column I}& \text{Column II}\\ \text{1.Right atrium}& \text{i. Receives oxygenated blood from the lungs}\\ \text{2.Left atrium}& \text{ii. Passes the blood to aorta}\\ \text{3.Right ventricle}& \text{iii. Receives deoxygenated blood from the superior}\\ & \text{vena cava and inferior vena cava}\\ \text{4.Left ventricle}& \text{iv. Passes the blood to lungs through the pulmonary artery}\end{array}$

1. 1-i, 2-iii, 3-iv, 4-ii
2. 1-iii, 2-ii, 3-i, 4-iv
3. 1-ii, 2-i, 3-iv, 4-iii
4. 1-iii, 2-i, 3-iv, 4-ii

Q.

Why is the left ventricular wall of the heart is thicker than the right ventricular wall?

1. To accommodate a greater volume of blood

2. To expand the thoracic cage during diastole

3. To pump blood with greater pressure

4. To pump blood through a smaller valve
