Components of the Blood
Plasma- About 55% of our blood. It is the liquid part of blood. It is mostly water.
Red blood cells- They are red because of the hemoglobin.
White blood cells- larger than red blood cells, and they have a nucleus. WBC help to defend against bacteria and viruses that get into the body.
Platelets - little fragments of cells. If a blood vessel gets damaged, the platelets help the blood to clot and seal the wound.
