Red blood cells are cells that carry oxygen and transport it to all cells of the body. It is round in shape with a flat center in the form of a donut, but without a hole in it.

Red blood cells... Carriers of oxygen and carbon dioxide

Red blood cells contain the iron-containing hemoglobin protein, which carries oxygen by binding to it, removes carbon dioxide from the body, and transports it to the lungs until it is eliminated through exhalation.

Red blood cells are made in the bone marrow, and their lifespan is 120 days.

Proper nutrition helps keep red blood cells healthy, including:

Iron-rich foods, such as meat.

Vitamins such as vitamin E, found in foods such as dark green vegetables, nuts, seeds, mangoes, and avocados, B vitamins: B2, B12, and B3 in foods such as eggs, whole grains, and bananas, folate in fortified cereals, dried beans, lentils, orange juice, and green leafy vegetables.

red blood cell diseases

Problems with red blood cells can be caused by diseases, iron deficiency, or a lack of vitamins in the diet, and some red blood cell diseases are hereditary.

Examples of red blood cell diseases include:

Iron deficiency anemia.

Sickle cell anemia, is a genetic disease in which the blood cells have a sickle shape instead of the normal round, and the cells become "sticky" and unable to flow smoothly in the blood vessels, and this causes a blockage in blood flow, which can lead to acute or chronic pain, and also can lead to organ damage.

Hemolytic anemia, in which red blood cells are destroyed by an abnormal process in the body before their lifespan ends, and as a result, the body does not have enough red blood cells to cover its need.

Symptoms of anemia include:

  • exhaustion.
  • Arrhythmia.
  • the pallor of the skin;
  • feeling cold.
  • In severe cases heart failure.
