$\underbrace\mathscr\red{White\:Blood\:Cells}$

• White Blood Cells or Leucocytes are colourless blood cells.
• They are colourless because they are devoid of haemoglobin.
• White blood cells are further classified as : lymphocytes, monocytes, neutrophils, eosinophils and basophils.

Function:-

• WBCs mainly contribute to immunity and defence mechanism.
• They are responsible for fighting foreign pathogens (such as bacteria, viruses, fungi) that enter our body.

$\underbrace\mathscr\red{Red\:Blood\:Cells}$

• RBC, also known as erythrocytes, are the principal means of delivering oxygen to the body tissues via blood flow through the circulatory system.
• They contain iron-rich protein called haemoglobin which gives blood its characteristic red colour.

Function:-

• Red blood cells carry oxygen from our lungs to the rest of our bodies.
• Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.

$\underbrace\mathscr\red{Platelets}$

• Platelets (thrombocytes) are colorless blood cells and are disc-like shape in structure.

Function:-

• Platelets help our blood to clot.
• They help to regulate blood flow when any part of the body is damaged, thereby aiding in fast recovery through clotting of blood.
