Blood physiology

Blood is a special type of connective tissue in which the ground substance is fluid instead of solid as occurs in other connective tissues.  It also has a fibrous and a cellular basis.

Its cellular basis is the blood corpuscle which is suspended in the matrix of fluid known as plasma.

 Plasma + Blood corpuscles  = Blood

When some amount blood is removed from the body and this blood is allowed to clot,   it releases a fluid called serum.

Serum  -  plasma  - clot

Clotting is effected by a substance called fibrinogen.  For clotting to occur, this protein fibrinogen is converted into fibrin which are fine fibers that trap the blood corpuscle to form clot.  It is therefore safe to regard the fibrin as the fibrous tissue of the blood connective tissue while the corpuscle remain the cellular basis.
