![]() Examine activation of the renin-angiotensin-aldosterone system (RAAS), and assess the effects of RAAS on glomerular filtration and renal tubule sodium transport processesĬ. Analyze how changes in renal sympathetic nervous system activity regulate glomerular filtration and renal tubule sodium transport processesī. Evaluate neurohumoral regulation of renal sodium handling, discuss which cellular processes are regulated, and explain the mechanism(s) by which these processes are regulatedĪ.Examine the cellular mechanisms involved in renal tubule sodium transport, and discuss the driving forces necessary for function of the various renal sodium transport processes, including the WNK system.Evaluate renal sodium handling, and identify the fraction of filtered sodium reabsorbed in the different nephron segments.Deduce appropriate IV fluid therapy based on volume status and serum electrolyte values Analyze how water and solute from a given IV fluid will partition into the body fluid compartmentsĬ. Examine the composition of IV solutions commonly employed in the treatment of disturbances in body fluid volumeī. Evaluate basic principles of intravenous fluid replacementĪ.Assess the driving forces for movement of water and solute across the barriers, and review the Starling forces Evaluate the mechanisms and processes that act to maintain the differences in composition between body fluid compartmentsĪ. Examine the properties of the barriers that impede net movement of water and solute between body fluid compartmentī. Examine the properties of the barriers that allow net movement of water and solute between body fluid compartmentsĬ.Compare the volume and composition of the major body fluid compartments.Identify the major body fluid compartments and the membrane barriers between the body fluid compartments.Cerebrospinal fluid, peritoneal fluid, pleural fluid, and synovial fluid, which serves as a joint lubricant, are all transcellular fluids.By the end of the week, students will be able to:īody Fluid Compartments and Principles of IV Fluid Replacement Plasma, the fluid part of blood, comprises about four percent of body weight and transcellular fluid, about 1.5%. ![]() Interstitial fluid, which is the fluid between tissue cells, comprises fifteen to sixteen percent of body weight. The three subcompartments of extracellular fluid are interstitial fluid, plasma, and transcellular fluid. Extracellular fluid is about twenty percent of body weight. Intracellular fluid, which is about forty percent of body weight, is the fluid inside tissue cells. Extracellular fluid and intracellular fluid, or ECF and ICF, are the two main fluid compartments of the body. Increased body fat or increased age lowers this percentage. Total body water accounts for about sixty percent of body weight for young men and for young women the percentage is about fifty percent. Student doctor, please pause the tape and summarize what we’ve discussed about the various fluid compartments of the body and what percent of body weight they comprise. Which one of these transcellular fluids serves as a joint lubricant? I’ll cue you with the first letters of each. Name four transcellular fluids alphabetically. What percent of body weight is transcellular fluid? What percent of body weight is interstitial fluid? Which one of these is the fluid between tissue cells? I’ll cue you with the first letter of each. About twenty percent of body weight is extracellular fluid.Īlphabetically, list the three subcompartments of the extracellular fluid.Intracellular fluid is the fluid inside tissue cells.Ībout what percent of body weight is intracellular fluid?.Extracellular fluid and intracellular fluid or ECF and ICF are the two main fluid compartments of the body.What are the two main fluid compartments of the body? As a person ages, the percentage also decreases.What effect does age have on the percentage? With increased body fat, totally body water accounts for a lower percentage of body weight. ![]() How does more body fat affect this percentage? What percent of body weight does total body water account for in young women? Total body water accounts for what percent of body weight for young men? ![]() Now let’s talk about fluid compartments of the body. Begin 58 08 Fluid Compartments Transcription
