The blood carries out critical functions of carrying oxygen
and nutrients to our cells and getting rid of waste
products. It also, plays a vital role in our immune system
and in maintaining a relatively constant body
temperature. Blood tissue is composed of many different
kinds of components. The most important ones are
erythrocytes, leukocytes, thrombocytes, and plasma.…read more

Thrombocytes are cellular components of blood that
help the clotting process. Thrombocytes are vital to life,
because they help prevent massive blood loss resulting
from trauma, as well as leakage that would occur in the
course of day-to-day activity.…read more

Plasma is the liquid in the blood, in which red and white blood
cells and platelets are suspended. Plasma, is 90 percent water,
and constitutes about 55 percent of blood volume. Plasma
serves a variety of functions, from maintaining a satisfactory
blood pressure and volume to supplying critical proteins for
blood clotting and immunity.…read more
