Components of Blood:

  • Plasma is yellowish color fluid present in blood, It’s mostly made of water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide.
  • Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood.
  • Platelets are tiny blood cells that help your body form clots to stop bleeding. Wherever a wound occurs, the blood vessel will send out a signal. Platelets receive that signal and travel to the area and transform into clusters to plug the wound until it heals.
  • Red blood cells represent 40%-45% of your blood volume. They are generated from your bone marrow at a rate of four to five billion per hour. They have a life cycle of about 120 days in the body.
  • White blood cells (leukocytes) only account for about 1% of your blood, they are very important. White blood cells are essential for good health and protection against illness and disease.

Like red blood cells, they are constantly being generated from your bone marrow. They flow through the bloodstream and attack foreign bodies, like viruses and bacteria. They can even leave the bloodstream to extend the fight into tissue.
