Question

Give one function each of RBC, WBC and platelets.​

Answer 1

The RBCs carry oxygen from the lungs. The WBCs help to fight infection, and platelets are parts of cells that the body uses for clotting.

Answer 2

Explanation:

Red blood cells (RBC):-

• RBC carry oxygen from the lungs
• Red blood cells are also called erythrocyte
• The red cell develops in bone marrow in several stages
• The average red cell in humans lives 100–120 days; there are some 5.2 million red cells per cubic millimetre of blood in the adult human.
• Though red cells are usually round, a small proportion are oval in the normal person, and in certain hereditary states a higher proportion may be oval.

White blood cells (WBC):-

• They protect you against illness and disease.
• White blood cell, also called leukocyte or white corpuscle
• A healthy adult human has between 4,500 and 11,000 white blood cells per cubic millimetre of blood.
• An abnormal increase in white cell number is known as leukocytosis, whereas an abnormal decrease in number is known as leukopenia.
• Although white cells are found in the circulation, most occur outside the circulation, within tissues, where they fight infections

Platelets:-

• Platelets, also known as thrombocytes, are blood cells responsible for blood clotting.
• If a blood vessel wall becomes damaged, platelets will rush to the site of injury and form a plug or clot to stop the bleeding. I
• Your doctor can help you assess your platelet count by looking at a complete blood count (CBC) test.
• The process by which platelets form a clot is called adhesion
• Platelets are live in the bloodstream for about eight to 10 days
