Isolated on its own, bloodplasma is a light yellow liquid, similar to the color of straw. Along with water,plasma carries salts and enzymes. The primary purpose of plasma is to transport nutrients, hormones, and proteins to the parts of the body that need it.

Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die.

White blood cell. ... White blood cells(also called leukocytes or leucocytes and abbreviated as WBCs) are thecells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.

Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals that arepicked up by platelets. The plateletsthen rush to the site of damage and form a plug, or clot, to repair the damage.

faltersainse [42]
