Detailed explanation-1: -When oxygen is added to haemoglobin, oxyhaemoglobin is produced. In the alveoli, where p is high and p is low, haemoglobin binds to oxygen. Oxyhaemoglobin is haemoglobin that has been bound to oxygen. Its function is to deliver oxygen to all of the body’s cells and tissues.

Detailed explanation-2: -Oxyhemoglobin. Oxyhemoglobin is formed during physiological respiration when oxygen binds to the heme component of the protein hemoglobin in red blood cells. This process occurs in the pulmonary capillaries adjacent to the alveoli of the lungs.

Detailed explanation-3: -Air that we inhale ends up in the alveoli of the lungs. From the alveoli, it diffuses to the blood stream. In the blood stream it combines with haemoglobin to form oxyhaemoglobin. This oxygen is taken inside the cells and carbondioxide is released.

Detailed explanation-4: -Hemoglobin is a red protein in your red blood cells that carries oxygen from your lungs to the rest of your body. It also returns carbon dioxide from your tissues back to your lungs. Hemoglobin levels play an important role in your ability to donate blood.

Detailed explanation-5: -In the lower concentrations of oxygen found in respiring tissues, the oxyhaemoglobin dissociates to release oxygen. Cells that have higher respiratory rates liberate the extra oxygen that they need.
