Solution
The main components of blood are
(i) Red blood cells (RBCs): Red blood cells are the most abundant
cells in the blood. These cells contain a red pigment called
haemoglobin. It is the haemoglobin which carries oxygen and
transports it to all parts of the body.
(ii) White blood cells (WBCs): WBCs are colourless cells without
haemoglobin. They fight against infections and protect the body from
foreign particles such as germs and bacteria.
(iii) Platelets: Platelets are the smallest cells in the blood. The
main function of platelet is to prevent bleeding.
