PATHOLOGY

Detailed explanation-1: -What do red blood cells do? Red blood cells are responsible for transporting oxygen from your lungs to your body’s tissues. Your tissues produce energy with the oxygen and release a waste, identified as carbon dioxide. Your red blood cells take the carbon dioxide waste to your lungs for you to exhale.

Detailed explanation-2: -Red blood cells at work Hemoglobin is the protein inside red blood cells. It carries oxygen. Red blood cells also remove carbon dioxide from your body, bringing it to the lungs for you to exhale. Red blood cells are made in the bone marrow.

Detailed explanation-3: -The protein inside (a) red blood cells that carries oxygen to cells and carbon dioxide to the lungs is (b) hemoglobin. Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen. It is the iron in hemoglobin that gives blood its red color.
