What is blood??

Opaque red liquid connective tissue consisting of microscopically visible, formed by red and white cells with platelets. suspended in a fluid called plasma.


Blood is composed of 55% plasma and 45% red, white blood cells and platelets. Its function is to carry nutrients and respiratory gases. There is enough blood in the human body to fill one or two one-gallon milk jugs, blood accounts for seven percents of your body weight.

Parts of Blood

All different types of white blood cells


Platelets are only 20% of the diameter of red blood cells. The normal platelet count is 150,000-350,000 per micro liter of blood, but because platelets are so small they only make up a tiny fraction of the blood volume. Main function- is to prevent bleeding.

Blood Clotting

Platelets in the blood work together with proteins found in the plasma, to stop the bleeding by forming a clot over the injury. Typically, your body will naturally dissolve the blood clot after the injury has healed. Sometimes, however, clots form on the inside of vessels without an obvious injury or do not dissolve naturally. These situations can be dangerous and require accurate diagnosis and appropriate treatments.

Plasma Proteins

Plasma can be broken down to proteins which include Albumins which is by far the most common, along with Globulin, and Fibrinogen.
