Answer:
Blood is composed of several types of cells:
- <u>RED BLOOD CELLS</u>: They are the oxygen carriers of the body i.e. they pick up the oxygen as the blood goes through the lungs & release of oxygen to cells.Also known as erthrocytes
- <u>WHITE BLOOD CELLS</u>: also known as leukocytes.They are the soldiers of the body.Aims at fighting against the infections ( caused by bacteria & virus)
- <u>PLATELETS</u> : helps in the blood clot in response to any wound or injury
There are five types of white blood cells & approx %age they made up in blood are:
•Neutrophils (55% to 70%)
•Band neutrophils (0% to 3%)
•Lymphocytes (20% to 40%)
•Monocytes (2% to 8%)
•Eosinophils (1% to 4%)
•Basophils (0.5% to 1%)
When children are more than 4 year old they have higher % age of lymphocytes than the adults do.
