Transporting nutrients: Our body contains millions of cells.In addition to the functions mentioned above, scientists recognize these other important roles of blood plasma and the components in blood plasma. Here is what to know about hematocrit levels and testing.īlood plasma has many functions, and different blood plasma components play different crucial roles. Doctors test hematocrit levels to check a person’s red blood cell count, which may affect their health. Red blood cells and the hemoglobin protein are essential in providing vital oxygen throughout the body. It carries it to the lungs, where the person breathes out the waste. Hemoglobin also picks up carbon dioxide waste. This allows hemoglobin to carry oxygen from the lungs to the rest of the body. Healthcare professionals consider hemoglobin one of the most important proteins for respiration (breathing) because it regulates levels of carbon dioxide and oxygen in the blood. Red blood cells in blood plasma contain the protein hemoglobin. Which protein is the most important buffer in blood plasma? Learn more about blood components and what they do. The immune system produces immunoglobulins to fight parasites, fungi, viruses, and bacteria. Immunoglobulins: Immunoglobulins make up around 20% of the total proteins in blood plasma.In blood plasma, they help regulate blood pH levels. Scientists understand that electrolytes have many functions around the body. Electrolytes: These include potassium, sodium, calcium, chloride, and bicarbonate.This coagulant is the primary component of a blood clot. The most common plasma coagulant is fibrinogen. Coagulants: Coagulants help with blood clotting, which is an important process that slows down bleeding.Plasma proteins: These proteins, which include globulin and albumin, help control pressure within a person’s circulatory system.Blood plasma is a yellowish liquid that makes up around 55% of blood.Īside from water, which makes up around 91–92% of blood plasma, the main components of blood plasma are: Whole blood contains red blood cells, white blood cells, and platelets suspended in blood plasma.
