Week 3 Physiology:

Formation of Eryrthrocytes (rbc's - no nucleus) Called Erythropoieses

Bone Marrow creates red and white blood cells as well as platelets for clotting. It makes RBC's when there is erythropoitin, a hormone released by the adrenal glands of the kidneys.

The hemoglobin molecule in the RBC's allows oxygen to bind with iron--

Anemia- low iron in the blood leading to reduced oxygen for cells. Anemic blood isn't good for recipients.

Why Anemic?
Blood loss

Bone marrow failure

Destruction of RBC's

Loss of Erythropoeitin (biofeedback malfunction)

Lack of Iron and/or B12 and/or folic acid in the diet. Required for erythropoieses
