Answer 2

Question :

• What are three types of blood cells???

Solution :

${\textsf{\textbf{\pink{\underline{Blood Cells }}}}} :$ There are three types of blood cells-red blood cells, white blood cells and platelets

${\textsf{\textbf{\red{\underline{Red Blood Cells (RBCs)}}}}} :$ They are discshaped cells. They contain a red coloured protein called haemoglobin, which absorbs the oxygen and transports it to the cells all over the body. The oxygen combines with haemoglobin to form oxyhaemoglobin. When the blood reaches the cells that need oxygen, it breaks down to form oxygen and haemoglobin. The oxygen is used by the cells for respiration and the haemoglobin

becomes free to carry more oxygen.

${\textsf{\textbf{\green{\underline{White Blood Cells (WBCs)}}}}} :$ These are generally bigger than the red blood cells. They lesser in number. They are of various shapes and they generally help in destroying the foreign particles and various harmful microbes. They help in building the immune system of the body by fighting various diseases. They are able to move on their own and that is how they go through the blood vessels and reach the infected parts of the body.

${\textsf{\textbf{\blue{\underline{Platelets}}}}} :$ The platelets are responsible for the clotting of the blood. In case of an injury, the platelets clot the blood and prevent further loss of blood from the body. This clotting of blood works as a defense mechanism in the human body. These are not cells but are formed by fragmentation of a large cell.
