Question

explain the importance of normal red blood cells in the human body

Answer 1

Most people don't think about their red blood cells unless they have a disease that affects these cells. Problems with red bloodcells can be caused by illnesses or a lack ofiron or vitamins in your diet. Some diseasesof the red blood cells are inherited.Diseases of the red blood cells include many types of anemia, a condition in which there are too few red blood cells to carry sufficient oxygen throughout the body. People with anemia may have red blood cells that have an unusual shape or that look normal, larger than normal, or smaller than normal.Symptoms of anemia include tiredness, irregular heartbeats, pale skin, feeling cold, and, in severe cases, heart failure. Children who don't have enough healthy red blood cells grow and develop more slowly than other children. These symptoms demonstrate how important red blood cells are to your daily life.These are common types of anemia:Iron-deficiency anemia.If you don't haveenough iron in your body, your body won't be able to make enough red blood cells. Iron-deficiency anemia is the mostcommon form of anemia. Among the causes of iron deficiency are a diet low in iron, a sudden loss of blood, a chronicloss of blood (such as from heavy menstrual periods), or the inability to absorb enough iron from food.
