Blood is considered to be the connective tissue for the following reasons:

The Embryological part of the blood that has the same origin as that for any other type of connective tissue. The blood is composed of the three components of the connective tissue fibres, matrix, and cells.

In this way, the blood vessels throughout the body, delivering essential oxygen, hormones, nutrients, and related signaling molecules. It is also eliminating waste.

That is, the circulating blood, there are two different types of cells. These are the elements of the enucleated during the and of the blood, or red blood cells, white blood cells, or the nuclear dna of white blood cells.

There are four groups FOR:

A: the surface of the red blood cells are the antigen, and plasma antibody B. Anti-B antibodies, which will attack the blood cells that are Oh-antigen.

“Group” means the surface of the red blood cells are the antigen, (B), and plasma antibodies against the a. A ranking of the “Anti-A” type-it will attack the blood cells as the antigen.

Group: time is of the blood of an element have the antigen (A) and (B), and the plasma contains antibodies against the A and Anti-B in People suffering from type (C) the EUROPEAN union can receive any blood type, ABO.

If the Plasma contains both anti-A and anti-B antibodies, but it is on the surface of the red blood cells, there is no A or B antigen. Because these antigens are not of the people, the ABO blood group may have this blood type.
