Blood is needed by all parts of the body as it is an important part of the transport system of our body. It performs the following important functions:

(i) It transports O₂ from the lungs to all the body cells.

(ii) It carries CO₂, a waste product back to the lungs so that it can be exhaled easily.

(iii) It transmits heat, thus regulating the body temperature.

(iv) It also fights off diseases and infections.

Blood has three main functions: transport, protection and regulation.
Transport
Blood transports the following substances:
Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body
Nutrients from the digestive tract and storage sites to the rest of the body
Waste products to be detoxified or removed by the liver and kidneys
Hormones from the glands in which they are produced to their target cells
Heat to the skin so as to help regulate body temperature
Protection
Blood has several roles in inflammation:
Leukocytes, or white blood cells, destroy invading microorganisms and cancer cells
Antibodies and other proteins destroy pathogenic substances
Platelet factors initiate blood clotting and help minimise blood loss
Regulation
Blood helps regulate:
pH by interacting with acids and bases
Water balance by transferring water to and from tissues

The role of the blood in our body: blood is a bodily fluid that deliveres necessary substances such as nutrients oxygen to the cells and transport metabolic waste products away from those same cells.
