What is Blood?
Blood circulates through the body delivering nutrients and removing waste
materials. Blood is made up of red blood cells, white blood cells, and platelets all
suspended in plasma.
Plasma-
About 55% of your blood is made up of plasma. Plasma is a liquid made up of
proteins, minerals, dissolved salts, and water.
Red Blood Cells-
Your body produces two million red blood cells every second. Red blood cells are
responsible for carrying oxygen from your lungs to your cells and for carrying
carbon dioxide from your cells to your lungs where it is exhaled.
White Blood Cells-
White blood cells defend the body against attack from foreign organisms, such as
bacteria and some viruses and form antibodies that protect the body from future
attacks.
If the body is invaded by harmful organisms, the production of white blood cells
increases dramatically. When a white blood cell encounters a smaller organism, it
simply engulfs it. If the invading organism is larger, a number of white blood cells
surround and consume it.
Platelets-
Platelets contain the enzymes needed to turn clotting agents into fibrin—fibrous
strands that heal wounds. Platelets collect around the edges of a wound, break
themselves open, and release enzymes that promote the chemical reaction needed
to heal the wound.
