What makes up most of the blood in the body?

Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. Blood is made up of the following four components: 1. Red blood cells. These make up 40-50% of blood by volume. Their function is to carry oxygen from the lungs to all parts of the body. 2. White blood cells.

How are the different types of red blood cells determined?

There are four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types ( A+, A- , B+, B- , O+, O- , AB+, AB- ).
