∙ Haemoglobin is a respiratory pigment that helps in transport of oxygen throughout the body.
∙ It is present in the red blood corpuscles.
∙ It has very high affinity for oxygen.
∙The deficiency of haemoglobin can affect the transport of oxygen in the body, leading to the deficiency of oxygen in the cells. This can make an individual feel weak, tired, and lightheaded, and can result in anaemia.
