Anemia describes a deficiency of which component?

Explanation:
The key idea is that anemia is a shortage of the components that carry oxygen in the blood. Red blood cells are the cells that transport oxygen, and hemoglobin is the protein inside those cells that actually binds and carries that oxygen. When there are too few red blood cells or not enough hemoglobin, the blood’s oxygen-carrying capacity drops, leading to symptoms like fatigue, weakness, and shortness of breath. This is different from issues with white blood cells (infection defense), platelets (clotting), or plasma (the fluid that carries blood components).
