Anemia is the reduction of either the number of red blood cells, or the amount of hemoglobin in the red blood cells. This results in a decrease in the amount of oxygen that the blood is able to carry.

Anemia reduces the amount of oxygen available in the cells of the body. As a result, you have less energy available to perform normal functions. Important processes, such as muscular activity and cell building and repair, slow down and become less efficient. When the brain lacks oxygen, dizziness may result, and mental faculties are less sharp.

Anemia constricts blood vessels. Therefore it causes a decrease in blood flow.

A lack of red blood cells makes blood thinner. This means that it would have increased flow speed and therefore the blood could carry less oxygen.
