Solution

The four main components of blood are:

  1. Plasma: It helps in the transport of food, carbon dioxide, wastes and salts.
  2. Erythrocytes (RBCs): They carry the oxygen from the lungs to all parts of the body.
  3. Leucocytes (WBCs): They fight infections and protect the body from foreign particles, like germs and bacteria.
  4. Platelets: They help in the coagulation of blood by releasing the chemicals that clot blood at the site of injury or wound.
