Plasma:Plasma is the clear, straw-colored fluid portion of the blood.Plasma is mostly ___water_____ but contains a variety of substances.What are plasma’s functions? Plasma proteins:The plasma proteins are the most abundant dissolved substances in the plasma.Briefly describe the functions of the following plasma proteins.Other Plasma Components:What are the two most important blood gases? The plasma nutrients include amino acids, monosaccharides, nucleotides, and lipids.Lipoproteins: HDL, LDL, VLDL, and chylomicrons.Nonprotein Nitrogenous Substances:Amino acids, urea, and uric acid. Urea and Uric acids are often disposed in the urine.Plasma electrolytesElectrolytes are absorbed by the intestine or are by-products of cellular metabolism. They include sodium, potassium, calcium, magnesium, chloride, bicarbonate, phosphate, and sulfate ions.Hemostasis:Hemostasis is the stoppage of __bleeding______.
Following injury to a vessel, three steps occur in hemostasis: vasospasm, platelet plug formation, and blood coagulation.Vasospasm causes smooth muscles in blood vessels to _contract_______ andlessens blood loss.Platelet plug formation occurs when platelets adhere to exposed __edges______ in broken blood vessels. A platelet plug is most effective on a small vessel.Coagulation:Blood coagulation is the most effective means of hemostasis. It is very complex and uses clotting factors.Damaged tissues release a chemical called tissue _thromboplastin____, which activates the first in a series of factors leading to the production of __prothrombin__ activator.This activator converts inactive __prothrombin____ in the plasma into __thrombin___. This in turn, catalyzes a reaction that converts soluble __fibronogen_____ into netlike ____fibrin______ causing the blood cells to catch in the net.
