Difference Between Plasma, Platelet, Red Blood Cells And White Blood Cells

Our blood is made up of  Plasma, Platelets,  Red Blood Cells, and White Blood Cells. 

Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Platelets are responsible for blood clotting.  Red blood cells are responsible for carrying oxygen and carbon dioxide. White blood cells are part of the immune system and function in the immune response.

• Plasma
  

  Plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. Plasma is the largest part of your blood. When separated from the rest of the blood. Plasma carries water, salts, and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. It makes up about 55% of the body's total blood volume. Plasma helps support your immune system and plays a critical role in clotting blood to prevent excessive bleeding. This is why plasma donations are so incredibly important – they help treat bleeding disorders, liver disease, and several types of cancer, among other conditions like Immune deficiencies.

• Platelet
  

  Platelets are very small blood cells, shaped like a disc. Platelets or thrombocytes are small, colorless cell fragments in our blood that form clots and stop or prevent bleeding, the principal function of platelets are to make your blood thicker so that it clots when you cut yourself. Platelets are made in our bone marrow, the sponge-like tissue inside our bones. The normal platelet count is 150,000-350,000 per microliter of blood, but since platelets are so small, they make up just a tiny the fraction of the blood volume.

• Red Blood Cells
  

  Red blood cells are a type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. Also called erythrocyte and RBC. Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin. The average red cell in humans lives 100–120 days; there are some 5.2 million red cells per cubic millimeter of blood in adult humans. Some diseases also display red cells of abnormal shape—e.g., oval in pernicious anemia, crescent-shaped in sickle cell anemia.

• White blood cells
  

  White blood cells are part of the body's immune system. They help the body fight infection and other diseases. In our body white blood cells account for only about 1% of our blood, but their impact is big. White blood cells are also called leukocytes. They protect you against illness and disease. White blood cells are made in the bone marrow. They are stored in your blood and lymph tissues. Because some white blood cells called neutrophils have a short lifeless than a day, your bone marrow is always making them. There are many types of White Blood Cells (Monocytes, Lymphocytes, Neutrophils, Basophils, Eosinophils) When your white blood cell count is low, you are at great risk for any illness or infection, which can spiral into a serious health threat. Many diseases and conditions may affect due to low white blood cell levels like Weak immune system, Infection, Cancer of the blood, Myelodysplastic syndrome, etc.
