ANATOMY

Detailed explanation-1: -Hemoglobin (Heme + Globin) The protein hemoglobin is a molecule which is responsible for carrying almost all of the oxygen in the blood.

Detailed explanation-2: -Haemoglobin molecules inside red blood cells pick up and carry the oxygen. These oxygen-rich cells travel in the blood vessels from the lungs to the left side of the heart. The blood is then pumped around the body.

Detailed explanation-3: –Hemoglobin is the protein responsible for oxygen transport and it is found almost entirely in RBCs, not dissolved in the plasma. The three most abundant plamsa proteins are albumins, globulins & fibrinogen. Albumins are important for carrying fat soluble substances & maintaining osmotic pressure of the blood.
