What is human blood made of and what differentiates blood type?

most of it is water the rest pigmentation die containing iron and other vital elements your body needs

If you receive blood that isnt yours depending on the quantity injected in your blood stream you die. If its a tap nothing but you could get diseases

Everyone's blood is made up of a fluid called plasma and three types of blood cells, red, white and platelets. Nearly half the blood, approximately 45% is made up of the various blood cells the remaining 55% is plasma.

There are 4 main blood groups A, B, AB and O, of which group O is the most common (47% of population). The blood type is determined by proteins called antigens found on the surface of red blood cells.

The primary types of blood are A, B, AB, and O.  This concerns two different proteins (A and B) either or both of which can be present.  There is an additional protein called Rhesus factor that is either positive or negative.

A person who has a protein in their blood can tolerate blood with that protein or without it.  For example, if you have A+ blood you can receive A+, A-, O+ or O- blood.  However, if you receive B or AB blood, you cannot tolerate the B protein, and the blood will clump in your veins.  This can cause huge infection-like problems as your immune system responds to the foreign protein.

AB+ people are called Universal Recipients, because they can receive any blood.  O- people are called Universal Donors, because anyone can receive their blood.  

There are additional proteins in blood that don't affect your ability to receive it, but were used to identify blood in the past, before they could do genetic analysis.  For example, at a crime scene they would find blood with certain proteins.  They could say that the person who left this blood was more likely to be eastern European than Asian or Black, and if they got a suspect who didn't have those proteins they could rule him out.  But if they had two people with the same proteins, they couldn't conclusively say that one person or other left the blood, the way you can with DNA.

there are 4 state of matter
solid, liquid , gas and plasma

your blood is plasma!
also ur blood contains a red pigments called hemoglobin ( which gives it the color red)

if you receive a wrong blood type.. blood clothing will occur inside the body which will almost lead to death
