How is blood formed?

Blood consists of RBCs, WBCs, platelets suspended in plasma. In early embryonic life blood cells are formed in liver and spleen. But by the fifth month the Haemopoisis (i.e., formation of blood) occurs in bone marrow and lymphatic tissues. At birth the entire bone marrow is red and active. Gradually as the child grows, the marrow remains red only in the flat bones and vertebrae. The RBC, grannulocytes of WBC and platelets are produced mainly by bone marrow. The lymphocytes, monocytes, plasma cells are formed in the lymphoid and Reticulo Endothelial tissues. The orderly proliferation of the cells in the bone marrow and their release into circulation is carefully regulated according to the needs of body. Every day, new blood cells are being produced in the bone marrow and every day old cells are dying and being removed from the body. Red blood cells have a life of 120 days and when it becomes old and senile it is thrown out. White cells live for a few days and platelets for a few hours. Thus, daily new cells are added to the circulation and old are removed from it.

What is haemoglobin?

Haemoglobin is a substance present in the red cells. It is helpful in carrying oxygen and carbon dioxide. On an average, in a healthy male it should be between 14-16 gm % and in a female it should be about 12-14 gm %. This is also being daily synthesized and the new is replacing the old stock.

What are blood groups?

Every individual has two types of blood groups. The first is called the ABO grouping and the second type is called Rh grouping. In the ABO group there are four categories namely A Group, B Group, O Group and AB Group. In the Rh Group either the individual is Rh-positive, or Rh-negative. Rh is a factor called as Rhesus factor that has come to us from Rhesus monkeys. Thus, each and every human being will fall in one of the following groups. A positive or A negative B positive or B negative O positive or O negative AB positive or AB negative There are also some sub groups as well as a few other classifications. FREQUENCY OF BLOOD TYPES O+ 1 person in 3 O- 1 person in 15 A+ 1 person in 3 A- 1 person in 16 B+ 1 person in 12 B- 1 person in 67 AB+ 1 person in 29 AB- 1 person in 167

What is the importance of knowing the blood groups?

For all practical and routine purposes, it is ideal to transfuse to the patient the same group of blood which he belongs to. It is only under very dire emergencies that we take O group as universal donor and AB groups as universal recipient. Under no circumstances O group can get any other blood except O. Similarly A group patient cannot be given B group blood and vice versa.

Why is A group not given B group blood?

This is due to the reason that the blood of A Group people contains anti-B antibodies. In B group people there are anti-A antibodies. If we give A group blood to a B group patient, it is bound to be incompatible and will result in serious consequences.In cases where a woman has Rh negative and her husband has Rh positive, the first child with Rh positive may be normal. But subsequently the woman may not conceive or may have repeated abortions. There may be intra uterine foetal death. If the child born is alive, it will suffer from a fatal disease called “Erythroblastosis Foetalis”. Now mothers can be given an injection of anti-D within 24 hours of the delivery of a Rh-positive child and thus protect the next baby from this catastrophe.

Why are Rh negative and Rh positive incompatible?

A patient with Rh-negative blood cannot be given Rh-positive blood as the antigen-antibody reactions will result in severe consequences.

What is a unit of blood?

Blood is collected in plastic bags which contain a watery fluid which prevents blood from getting coagulated. On an average we draw about 450 ml of blood from a person, depending on the weight of the donor. This blood, plus the amount of anti coagulant present in the bottle or bag, is known as one unit of blood.
