Summary Introduction
To review:
The reason that athletes often move to elevations higher than those, at which they will compete, several months before a competition.
Introduction:
Red Blood Cells (RBCs) play an important role in the body of an organism. They carry oxygen from lungs to different tissues. RBC is produced in red bone marrow and each has a lifespan of 120 days. The level of hemoglobin or number of RBCs determines the oxygen transport to the tissues. Hemoglobin is a globular protein, which contains two alpha chains, two beta chains and a non-protein pigment called heme. There are four heme units in one hemoglobin molecule and each heme unit can hold an iron, which binds to an oxygen molecule.
