Question

What approximate percentage of lymphocytes is seen at age 4?

Answer 1

Blood is composed of several types of cells:

• RED BLOOD CELLS: 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
• WHITE BLOOD CELLS: also known as leukocytes.They are the soldiers of the body.Aims at fighting against the infections ( caused by bacteria & virus)

• PLATELETS : 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.
