What is the role of blood …

Main Functions of blood:

1. Oxygen carrier: With the help of haemoglobin in the RBCs, O₂ is transported to various tissues.
2. Removal of CO₂: Blood plasma contains Na₂CO₃ which absorbs CO₂ to form NaHCO₃ which on decomposition gives CO₂ with the lungs from where it is thrown out.
3. Transport of food material: The digested food materials are assimilated by the blood in liquid form from the intestine and is taken by the blood to various tissues.
4. Removal of waste material: Blood helps to discharge the metabolic waste from the body.
