tell about blood and their types :- RBC,WBC, platelets and lymph
Answers
Blood circulates through our body and delivers essential substances like oxygen and nutrients to the body's cells. It also transports metabolic waste products away from those same cells. There is no substitute for blood. It cannot be made or manufactured.
RBC :- Red blood cells, also referred to as red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues—via blood flow through the circulatory system.
WBC :- The white blood cell count (WBC) is used as part of a full complete blood count (CBC) to: Screen for a wide range of diseases and conditions. Help diagnose an infection or inflammatory process or other diseases that affect the number of WBCs, such as allergies, leukemia or immune disorders, to name a few.
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 and form a plug (clot) to fix the damage.
Lymph :- Lymph is the fluid that flows through the lymphatic system, a system composed of lymph vessels and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to the central circulation.
