Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hem
aalyn [17]

Answer:

c. Anemic hypoxia

Explanation:

Hypoxia is a health condition in which the body or a region of the body is not adequately supply with oxygen  at the tissue level. Types of hypoxia include:

Hypoxemic hypoxia is a condition in which their is low level of oxygen in blood in the arteries due to the inability of the lungs to properly oxygenate blood.

Ischemic (stagnant) hypoxia is a type of hypoxia that occurs due to a decrease in blood flow preventing adequate blood supply to tissues.

Anemic hypoxia occurs when the ability of the blood to carry oxyegen is reduced due fewer red blood cells or red blood cells that contain little or abnormal hemoglobin molecules hemoglobin molecules.

Histotoxic hypoxia is hypoxia in which the cells are unable to use oxygen from the bloodstream, even though there is normal delivery of oxygen to such cells and tissues. This is due to the poisoning of the cells or tissues causing a disruption in their respiratory mechanism, for example in Cyanide poisoning.

<em>Therefore, the correct answer is anemic hypoxia.</em>
