Some Fact About Blood Group Everyone Should Know 

Know everything about Blood Group - A Quick Guide

Has it ever happened that a relative of yours was in need of blood, and you could not help him just because you did not know your blood group? It has often been seen that many people do not consider it necessary to keep such important information about themselves, or they do not pay attention to it. That's why everyone should know about their blood group, so that along with themselves, the lives of others can be saved. 


Types of blood group 

There are four types of blood group - A, B, AB and O. Each group is RH positive or RH negative, due to which the blood group increases from four to eight. The human body contains about four to six liters of blood. Blood is made up of red, white blood cells and platelets present in the plasma. Plasma consists of 90 percent water, which contains proteins, nutrients, hormones. Sixty percent plasma and 40 percent blood cells play a role in the formation of blood. 



Blood cells and platelets 

Red blood cell
The red color of blood is due to these cells. Their job is to deliver oxygen to every part of the body, remove carbon dioxide and impurities from the body.

White blood cells
They are part of the body's natural defense system and help fight infections.

Platelets thicken the blood and prevent any kind of bleeding in the body. 



Blood group information 

The blood group is determined by the antigens and antibodies present in it. Antigens are protein molecules that are present on the surface of red blood cells, while antibodies are proteins present in the plasma, which alert the immune system to fight foreign bacteria when attacked. There are two types of antigens, which are named A and B. 



ABO system 

Blood group A
A person who has anti-B antibodies in the plasma with type A antigens on their blood cells, their blood group is A.

Blood group B
A person who has anti-A antibodies in the plasma along with type B antigens on their blood cells, their blood group is B.

Blood group AB
A person who has both A and B antigens on their blood cells and no antibodies, their blood group is AB.

Blood group O
A person who has no antigen present on his blood cells but has both anti-A and B antibodies in the plasma, his blood group is O.

RH factor
It is important to know about the RH factor of the blood along with the blood group. There are two types of RH factor. First, RH positive and second, RH negative. If there are RH antigens on the red blood cells, then that person is RH positive and those who do not have the antigen are RH negative, for example - if someone's blood group is A, and it is RH positive, then it will be called A positive.



Health connection 

Many times it happens that among two people of the same stature and same lifestyle, one is often ill and the other is completely fit. Its connection is with blood. Any genetic disease can be detected through a blood test. Research has found that there are certain blood groups that have a higher risk of getting certain types of diseases.

A type blood group
Women of this group have good fertility, but they are more prone to infection. Individuals with A blood group tend to feel stressed quickly, as their body has higher levels of the hormone cortisol, which is responsible for stress.

O type blood group
People with this group may have a low risk of heart disease, but problems like stomach ulcers may occur.
