Plasma

PLASMAThe blood plasma is about 90% water and most of the substance which must be transported and dissolved in it consist of :Dissolved food (glucose, amino acids, fatty acids, glycerol)CO2 as HCO2- ion (bicarbonate ions)Nitrogenous wastesHormonesMineral salts (Na+, K+, Cl+The main functions of plasma is to transport:Dissolvved foods drom the ileum to tissuesCO2 as the HCO2- ionfrom tissues to lungsOther waste from tissues to excreting gorgansHormones from endrocine glands to target organsHeat from muscles and liver to all the body partsIons and water to mainkran the correct concentration of body fluidsWhite blood cells and antibodies to sites of infectionPlatelets and plasma proteins to cutsThe difference from Plasma to Tissue fluidsPasma is the liquid part of bloodor lymph as distinguished from the suspended elementsLymph - a clear yellowish slightly alkaline coagulate fluid, containing white blood cellsTissue fluids - A collection of similar cells and cell products forming a watery solution of salts, glucose and other solutesPlasma is rich in food and O2 is formed out of capillaries where they branch from atteries , this forms tissue fluid cells absorbed food and 02 from tissue fluids and give out CO2 and water wastes
