Plasma fulfills the function of immune protection against possible infections to which the body can be exposed. Substances secreted into the plasma by cancers may indicate an occult malignancy; for instance, an increased concentration of prostate-specific antigen (PSA) in a middle-aged asymptomatic man may indicate undiagnosed prostate cancer. … Cells also put their waste products into the plasma. Plasma also helps maintain body temperature by absorbing and releasing heat as needed. Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood … Plasma accepts and transports this waste to … By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica.

Coagulation inhibitor proteins help to prevent abnormal coagulation (hypercoagulability) and to resolve clots after they are formed. Other cytokines stimulate the production of white blood cells and platelets. Blood Transfusions: What to Expect and How Long They Last, Debra Rose Wilson, Ph.D., MSN, R.N., IBCLC, AHN-BC, CHT, How to Clean Your Blood: Herbs, Foods, and More, The 8 Best Veggie Burgers for Your Meat-Free Routine, The 11 Best Meal Planning Apps to Help You Lose Weight, The 5 Best Calorie Counter Websites and Apps, The 10 Best Weight Loss Apps That Help You Meet Your Goals, have not donated plasma in the last 28 days. Topics covered include: Introduction to blood components and blood plasma proteins; Blood plasma protein domains, motifs and repeats Besides the cells, it transports nutrients and carries away waste to be processed by the kidneys and liver. This is performed through a method known as plasmapheresis. The gamma globulins, or immunoglobulins, are an important class of proteins that are secreted by B lymphocytes of the immune system. Maintain Colloidal Osmotic Pressure of Blood and Aid in Regulating the Dis­tribution of Fluid between Blood and Tissue: All the three proteins take part. Essential for Blood Clotting: Fibrinogen and prothrombin are essential for coag­ulation of blood and take part in this process Fig. Dissolved in the plasma are: Any changes that occur in the body will be detected, as well as if there is bleeding. Let us know if you have suggestions to improve this article (requires login). When blood clotting is activated, fibrinogen circulating in the blood is converted to fibrin, which in turn helps to form a stable blood clot at the site of vascular disruption.

Plasma is derived when all the blood cells—red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes)—are separated from whole blood. The electrolytes and acid-base system found in the plasma are finely regulated. Cytokines are proteins synthesized by cells of various organs and by cells found in the immune system and bone marrow in order to maintain normal blood cell formation (hematopoiesis) and regulate inflammation. Transporting Electrolytes throughout the Body.
