All You Need To Know About Blood Groups

Blood is a very important fluid in our bodies. Blood is
required in any kind of emergency. Giving blood to others who are in need is
very good because giving blood helps the patient as well as helps you to
control your blood pressure level. But, before giving blood to any patient you
must know your blood group. Because without knowing your blood groups you will
not be able to donate blood to others. Also, the name should be known because
it is required in professional areas also. So, today we will be discussing some
relevant facts about blood groups.

Definition of Blood Groups

When we used to be in our childhood, we thought that all
groups are the same because the color of blood is red for all. But as we grew
up, we studied and we came to know that there are different types of blood
groups available in different human bodies. So, before donating blood to any
patient it is required that the donor knows his/her blood group because the
mixing of other blood groups in any patient’s body can be very dangerous and
deadly without knowing what kind of blood is required by the patient. In
science, we have read that a human body contains millions of red blood cells.
Let’s talk in more detail.

How to discover blood groups?

Donation of blood was started in the 17th century,
but blood groups were discovered in the 20th century. Due to
this reason, animal’s blood was transferred to human bodies when required and
it causes fatal diseases because animal blood is not suitable for human bodies.
This resulted in a weak immunity system, infections, and other hazardous
diseases. And due to these fatal diseases harmed the human bodies, transferring
blood from animals was stopped. After that many scientists started
experimenting and found that ABO blood group is the safest blood group and can
be transferred to any human body without involving any risk factor. After that
many experiments were done and after 1930 human blood was used in human bodies
after knowing their blood groups.

Why blood grouping is important in the present time?

A correct blood group is required before donating it to any
patient whoever requires it. Because if a patient is given the wrong group’s
blood then it can cause certain hazardous problems which in-turn causes death
to the patient? After injecting the donor’s blood into the patient’s body it
immediately starts reacting with the patient’s blood cells and tissues. So, it
