Answer:
Anemia is a condition in which the blood has a lower amount of red blood cells or hemoglobin than in a healthy individual. As a result, enough oxygen is not transported to the cells and tissues where they are needed.
Step-by-step explanation:
The red blood cells found in blood function to transport oxygen from the lungs to the cells and tissues where they are needed. The molecule that helps the red blood cells to perform this function is called hemoglobin. Iron is required by the body to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood due to the heme molecule in hemoglobin. each hemoglobin molecule is able to bind four oxygen molecules.on inspiration, air fills the lungs and diffuses through the alveoli sacs into the capillaries carrying oxy-deficient blood from the lungs. The oxygen molecules diffuse into the red blood cells and are bound to hemoglobin in the red blood cells. From the lungs, the red blood cells transport the oxygen and deliver it to the cells and tissues.
However, in an individual with anemia, transport of oxygen to the tissues is impaired and the individual develops symptoms such as fatigue, dizziness, and shortness of breath, etc. Eating foods rich in iron can help to improve the individual's condition.
