what is the importance of RBC,WBC and Platelets in blood?
Answers
Explanation:
RBCs contain a red pigment called haemoglobin which imparts the red colour to the blood.
WBCs fight against infections.
Platelets help in clotting of blood.
Answer:
BLOOD:
Blood consists of 45% red blood cells, less than 1% white blood cells and platelets, and 55% plasma.
☆RBC(Red Blood Cells)
>Red blood cells are an important element Red blood cells are an important element of blood.
>Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which is carried to and eliminated by the lungs.
>Red blood cells are formed in the red bone marrow of bones.
☆WBC(White Blood Cells)
>It fight against the gems present in our body.
Types of WBCs
>WBCs, also called leukocytes, are an important part of the immune system.
>These cells help fight infections by attacking bacteria, viruses, and germs that invade the body.
>White blood cells originate in the bone marrow but circulate throughout the bloodstream. There are five major types of white blood cells:
*neutrophils,
*lymphocytes,
*eosinophils,
*monocytes,
*basophils.
☆PLATELETS:
>Platelets are tiny blood cells that help your body form clots to stop bleeding.
>If one of your blood vessels gets damaged, it sends out signals to the platelets.
>The platelets then rush to the site of damage.
>They form a plug (clot) to fix the damage.
>The process of spreading across the surface of a damaged blood vessel to stop bleeding is called adhesion.
>This is because when platelets get to the site of the injury, they grow sticky tentacles that help them stick (adhere) to one another.
>They also send out chemical signals to attract more platelets.
> The additional platelets pile onto the clot in a process called aggregation.
Facts about platelets
*Platelets are made in your bone marrow along with your white and red blood cells. *Your bone marrow is the spongy center inside your bones.
*Another name for platelets is thrombocytes. Healthcare providers usually call a clot a thrombus.
*Once platelets are made and circulated into your bloodstream, they live for 8 to 10 days.
*Under a microscope, a platelet looks like a tiny plate.
