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.
