  3. It carries oxygenated blood from the lungs to the heart.

  4. It carries deoxygenated blood from the heart to the lungs.

  5. None of the options show the correct answer.

Show answer
Correct Option: D

In a unicellular organism, transportation of gases takes place through __________.

  1. diffusion

  2. osmosis

  3. active transport

  4. circulatory system

  5. all of these

One heart beat indicates _______________.

  1. pumping of blood from right auricle to left auricle

  2. pumping of blood from left side of heart to the aorta

  3. pumping of blood by all the four chambers

  4. pumping of blood from systemic vein to the right auricle

  5. pumping of blood from right auricle to pulmonary artery

Show answer
Correct Option: C
Explanation:

Yes, it is correct. While pumping the blood, different chambers of the heart contract and relax in turns. The contraction and relaxation of different chambers produces a thumping sound. One heart beat indicates one cycle of pumping action by all the four chambers.

Which of the following takes place during the process of exhalation?

  1. Rib cage contracts

  2. Lung expands

  3. Diaphragm lowers down

  4. Oxygen moves out

  5. All of these

Show answer
Correct Option: A
Explanation:

 When the diaphragm moves up, the ribcage contracts. This leads to contraction of the lungs. As a result, the air moves out of the lungs. This process is called expiration or exhalation.

Which of the following options show the correct path of blood flow?

  1. From the body → Right Auricle → Right Ventricle → Pulmonary Artery → Lungs → Pulmonary Vein → Left Auricle → Left Ventricle → To the body

  2. From the body → Left Auricle → Left Ventricle → Pulmonary Artery → Lungs → Pulmonary Vein → Right Auricle → Right Ventricle → To the body

  3. From the body → Right Auricle → Right Ventricle → Pulmonary Vein → Lungs → Pulmonary Artery → Left Auricle → Left Ventricle → To the body

  4. From the body → Right Auricle → Right Ventricle → Pulmonary Artery → Lungs → Pulmonary Vein → Left Auricle → Left Ventricle → To the body

  5. From the body → Right Auricle → Left Auricle → Pulmonary Artery → Lungs → Pulmonary Vein → Left Ventricle → Right Ventricle → To the body

Show answer
Correct Option: A
Explanation:

Yes, it is correct. The upper chambers are called auricle or atrium. The lower chambers are called ventricles. Left side of the heart had oxygenated blood and right has the deoxygenated blood.

  4. upper chamber of the heart contracts and the blood rushes upward into the aorta

  5. upper chamber of the heart contracts to squeeze the blood downward into the ventricles

Show answer
Correct Option: E
