What is Hbg?

Hbg, or hemoglobin, is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the body's tissues and facilitating the return of carbon dioxide to the lungs for exhalation. It consists of four subunits, each containing an iron atom that binds to oxygen. Hemoglobin levels are commonly measured in blood tests to assess a person's overall health and can indicate conditions such as anemia or respiratory issues.
