Read the following statements (A – D).(A) The movement of air in and ...
The correct answer is option C, two of the statements are correct.
Explanation:
(A) The movement of air in and out of the lungs is carried out by creating a pressure gradient between the lungs and atmosphere.
(B) Inspiration can occur if the pressure within the lungs is more than the atmospheric pressure.
(C) Expiration takes place when the intrapulmonary pressure is lesser than the atmospheric pressure.
(D) The diaphragm and a specialized set of intercostal muscles in between the ribs help in the generation of such pressure gradients for breathing.
Let's analyze each statement:
(A) The movement of air in and out of the lungs is carried out by creating a pressure gradient between the lungs and atmosphere.
This statement is correct. The movement of air in and out of the lungs is achieved by creating a pressure gradient. During inspiration, the diaphragm contracts and the intercostal muscles expand the rib cage, increasing the volume of the thoracic cavity and decreasing the pressure within the lungs. This creates a pressure gradient, causing air to flow into the lungs. During expiration, the diaphragm relaxes and the intercostal muscles contract, decreasing the volume of the thoracic cavity and increasing the pressure within the lungs. This creates a pressure gradient, causing air to flow out of the lungs.
(B) Inspiration can occur if the pressure within the lungs is more than the atmospheric pressure.
This statement is incorrect. Inspiration occurs when the pressure within the lungs is less than the atmospheric pressure. When the pressure within the lungs decreases during inspiration, air flows into the lungs to equalize the pressure.
(C) Expiration takes place when the intrapulmonary pressure is lesser than the atmospheric pressure.
This statement is correct. Expiration occurs when the intrapulmonary pressure (pressure within the lungs) is greater than the atmospheric pressure. When the pressure within the lungs increases during expiration, air flows out of the lungs to equalize the pressure.
(D) The diaphragm and a specialized set of intercostal muscles in between the ribs help in the generation of such pressure gradients for breathing.
This statement is correct. The diaphragm and the intercostal muscles play a crucial role in the generation of pressure gradients for breathing. The diaphragm contracts and the intercostal muscles expand the rib cage during inspiration, and relax and contract during expiration to create the necessary pressure changes.
In summary, statements (A) and (C) are correct, while statements (B) and (D) are incorrect. Therefore, the correct answer is option C, two of the statements are correct.

Community Answer
Read the following statements (A – D).(A) The movement of air in and ...
Statement B and C are wrong, because inspiration occurs if the pressure within the lungs (intra-pulmonary pressure) is less than the atmospheric pressure, i.e., there is a negative pressure in the lungs with respect to atmospheric pressure. Expiration takes place when the intra-pulmonary pressure is higher than the atmospheric pressure, i.e., there is positive pressure in the lungs with respect to atmospheric pressure.
