The 2 components of blood are : Blood Plasma and Blood Cells
- Blood Plasma : This is the liquid component of
the blood in which the cellular component of blood is suspended. It
is a homogenous suspension of sugar, fat, protein and salts in
water. The main function of plasma is to transport blood cells
throughout the body along with nutrients, waste products,
antibodies, clotting proteins, chemical messengers such as
hormones, and proteins that help maintain the body's fluid
balance.
- Blood cells : Blood cells can be classified as
Red Blood Corpuscles (RBCs/Erythrocytes),
White Blood Cells (WBCs/Leukocytes) and
Platelets (Thrombocytes). RBCs
are the most abundant cell in the blood, accounting for about 40 to
45 percent of its volume.RBCs contain haemoglobin which is
responsible for transportation of oxygen molecules throughout the
body. WBCs form the immune system of body They are
much fewer in number than red blood cells, accounting for about 1
percent of your blood. Platelets help
the blood clotting process (or coagulation) by gathering at the
site of an injury, sticking to the lining of the injured blood
vessel, and forming a platform on which blood coagulation can
occur.
