HEART AND CIRCULATORY SYSTEM (Part-I)

Hemoglobin is responsible for oxygen transport in humans. Haemoglobin in the blood transports oxygen from the lungs to the rest of the body, the tissue, where it releases the oxygen for use by cells.

Anaemia is a condition in which there is a lack of red cells or haemoglobin in the blood. Common symptoms include fatigue, pale skin, difficulty in breathing, dizziness or light-headedness. For its treatment, an adequate amount of iron and folic acid should be given.
