Major Components & Function of Blood.
The four major Blood Components are
•Plasma is the liquid part of the blood that is made up of 55% fluid, this is the blood’s liquid medium, by itself is straw-yellow in colour. The total volume of blood plasma is about 2.7-3.0 litres in human. The plasma carries carbon dioxide , hormones and waste.
•Red blood cells
•The red blood cells are called erythrocytes, the red blood cells contain hemoglobin which carries oxygen.
•Made in the bone marrow. The more you train the more blood cells are produced.
•White blood cells
•The white blood cells are called leukocytes. White blood cells fight …show more content…
•Platelets helps blood clotting, it is used to treat cases of bone marrow failure
•Following a transplant or chemotherapy treatment
•Can also be used to treat leukaemia.
•Plasma is the fluid that carries all blood cells and components.
•Plasma contains all the proteins which is need in the body.
•Plasma contains, albumin-a protein which is useful in treating kidney and liver diseases
•Clotting factors which is used to treating certain types of haemophilia and diseases.
•Immunoglobulins- these are antibodies which is used as a protection against infections.
Functions of blood
•Transport: Blood is the primary means of transporting nutrients throughout the body, for instance Glucose, amino acids, vitamins, and minerals are carried from the small intestine to cells in the body
•Red blood cells carries oxygen from the lungs to body body cells.
•Blood helps in getting rid of carbon dioxide, ammonia, urea, and other waste products.
•The hormones are internal secretion which helps to control the important body processing , which is being transported by the blood to the organs.
•Defence: The white blood cells which is otherwise known as leukocytes is for fighting infection and …show more content…
These cell lines were obtained, by culture and representing the replicating cell lines. Since the cells do not grow as tumours, in the process of a living organism, it’s considered that they may have retaining and relating to their other cell counterparts. Capacity to migrate to various lymphoid sites,example: spleen, bone marrow, thymus and mesenteric lymph node.This suggests that the NK/lymphoid precursor cells may exist which have capacity to recirculate widely through the lymphoid system. The stem cell (hemocytoblast) gives rise to cells that undergo several mitotic divisions together with cytoplasmic division to produce the megakaryocytes. The cytoplasm of the megakaryocyte becomes compartmentalised by membranes. The plasma membrane the fragments, freeing the
