MEDICAL PHYSIOLOGY

Detailed explanation-1: -Platelets help blood to clot Platelets are irregularly shaped fragments of cells that circulate in the blood until they are either activated to form a blood clot or are removed by the spleen. Thrombocytopenia is a condition of low levels of platelets and carries an increased risk of bleeding.

Detailed explanation-2: -One of the key functions of blood is transport. Blood vessels are like networks of roads where deliveries and waste removal take place. Oxygen, nutrients and hormones are delivered around the body in the blood and carbon dioxide and other waste products are removed.

Detailed explanation-3: -Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body. The main job of white blood cells, or leukocytes, is to fight infection.

Detailed explanation-4: -Function. Plasma is a watery fluid in which holds all the components of blood flow.
