Plasmavätskan

Plasmavätskan, also known as plasma or blood plasma, is the clear, straw-colored liquid component of blood that remains after the removal of blood cells and other cellular elements. It constitutes approximately 55% of total blood volume and plays a vital role in maintaining blood circulation and homeostasis.

Plasmavätskan is primarily composed of water (about 90%), but also contains dissolved substances such as electrolytes (sodium, potassium, chloride), nutrients (glucose, amino acids, lipids), hormones, waste products (urea, creatinine), and proteins. Key plasma proteins include albumin, globulins, and fibrinogen, which are essential for maintaining osmotic pressure, immune responses, and blood clotting functions.

One of the crucial functions of plasmavätskan is to transport nutrients, hormones, and waste products throughout the body. It also helps regulate blood volume and pH balance. The plasma's protein components, especially albumin, contribute to maintaining blood osmotic pressure, ensuring proper fluid distribution between blood vessels and tissues.

Plasmavätskan is used therapeutically in various medical treatments, such as plasma exchange therapy and the production of plasma-derived medications like immunoglobulins and clotting factors. It can be obtained through blood donation, where plasma is separated from blood cells via centrifugation.

In summary, plasmavätskan is a vital component of blood, facilitating transportation, regulation, and immune functions. Its importance in health and disease underscores its significance in medical research and treatment.
