Hemoglobin (Hb or Hgb) is a protein in red blood cells that plays a crucial role in transporting gases throughout the body. Here’s a concise explanation:
🩸 What Is Hemoglobin?
– Function: Hemoglobin carries oxygen from the lungs to tissues and returns carbon dioxide from tissues to the lungs for exhalation.
See less– Structure: It consists of four globin chains—two alpha and two beta in adults—each bound to a heme group containing iron.
– Iron Role: The iron in heme binds oxygen, giving blood its red color and enabling oxygen transport.
– Importance: Without hemoglobin, cells wouldn’t receive enough oxygen, leading to fatigue, weakness, and other symptoms of anemia.
