MCQ IN MEDICINE

Detailed explanation-1: -Hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia).

Detailed explanation-2: -Anemic anoxia is occurs when red blood cells lack the ability to carry sufficient oxygen, either due to a reduction in hemoglobin or due an alteration in the capacity of the hemoglobin to carry oxygen. It may also be the result of a deficiency in red blood cells.

Detailed explanation-3: -Anoxia and hypoxia may be caused by a number of events, such as smoke or carbon monoxide inhalation, high altitude exposure, strangulation, anesthetic accidents, or poisoning.
