MICROANATOMY

Detailed explanation-1: -Iron is an essential element for blood production. About 70 percent of your body’s iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin . Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues.

Detailed explanation-2: -More specifically, though, it’s the hemoglobin in red blood cells. Hemoglobin contains iron, which allows it to pick up oxygen from the air we breathe and deliver it everywhere in the body. You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells.

Detailed explanation-3: -Haemoglobin is made up of a simple protein, called globin and a non-protein also known as haem(iron containing part)

Detailed explanation-4: -Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. Checking the number of red blood cells in the blood is usually part of a complete blood cell (CBC) test. It may be used to look for conditions such as anemia, dehydration, malnutrition, and leukemia.

Detailed explanation-5: -hemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals-in the red blood cells (erythrocytes) of vertebrates-that transports oxygen to the tissues.
