LIFE SCIENCE

Detailed explanation-1: -A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.

Detailed explanation-2: -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.

Detailed explanation-3: -Aside from the sugar (glycan or carbohydrate) antigens, the red blood cell membrane contains three types of protein that carry blood group antigens: single-pass proteins, multi-pass proteins, and glycosylphosphatidylinositol (GPI)-linked proteins.

Detailed explanation-4: -A mature red blood cell is called an erythrocyte. An erythrocyte is a fully mature red blood cell that primarily functions by transporting respiratory gases, particularly oxygen and carbon dioxide. Most vertebrates have red blood cells that remain nucleated.
