Solution:

Blood is a red-coloured fluid that runs in arteries and veins and transports material from one organ to another. Blood carries oxygen and carbon dioxide from the tissues of the body. Blood contains plasma and blood corpuscles (Red Blood Cells, White Blood Cells and platelets).

The blood cells are synthesised inside the bone marrow. The bone marrow is a mass of cells found inside the bones.

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.

(iv) Plasma : The fluid part of blood is called plasma
