MCQ IN MEDICINE

Detailed explanation-1: -Resorptive atelectasis happens when the oxygen and carbon dioxide in your alveoli move into your bloodstream and no new air moves in. This causes your alveoli to collapse. Surgery that requires anesthesia is a common cause of resorptive atelectasis.

Detailed explanation-2: -Atelectasis (at-uh-LEK-tuh-sis) is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. Atelectasis is one of the most common breathing (respiratory) complications after surgery.

Detailed explanation-3: -Accordingly, atelectasis can decrease the level of oxygen in the blood. The body compensates for a small amount of atelectasis by closing off (constricting) the blood vessels in the affected area. This constriction redirects blood flow to alveoli that are open so that gas exchange can continue.
