Fluid‚ Electrolyte‚ and pH Balance 1. The maintenance of normal volume and composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved. In males and females‚ intracellular fluid has a greater proportion of total body water than does extracellular fluid. Give-and-take between the ICF and the ECF happens across plasma membranes by osmosis‚ diffusion‚ and carrier-mediated transport. The kinds of homeostasis involved are fluid

Chapter 1 - The Human Body Anatomy is the science relating to the structural organisation of living organisms. Physiology is the science relating to the operational functions of living organisms. The many parts and systems of the body are integrated and function co-operatively to provide a healthy living body via 6 hierarchy levels of structural organisation. The basic or first level is the Chemical Level‚ where atoms are combined to form molecules. The second level is the Cellular Level

Plant Physiology Review for Quiz 4/09/13 1. What is Plant Physiology? Plant physiology is the study of the functions of plants. 2. What is the difference between phenotype and genotype The difference between phenotype and genotype is that phenotype is the external characteristics and genotype is the genetic make up 3. What are the two types of cell walls? The two types of cell walls are primary cell wall and secondary cell wall. 4. What are the most abundance components of the CELL

to vasoconstriction and reversible mild renal impairment in volume contracted states. When unopposed‚ this may lead to acute tubular necrosis and acute renal failure. NSAIDs also produce interstitial nephritis with or without nephrotic syndrome secondary to minimal change disease. Although this presents as acute renal failure‚ it can progress in some cases to chronic renal failure. Papillary necrosis has been incriminated in the development of chronic renal failure secondary to NSAIDs. In patients

there is impairment (renal failure)‚ then a person relies on dialysis to artificially clean the blood‚ remove excess fluid and electrolytes. The patient will have to go to a facility to have this done on a routine schedule. The dialysis machine uses dialysate solution to maintain diffusion gradients that help with removing waste and add other substances; meanwhile the patient will also be heparinized to prevent clotting during the procedure. Patients with renal disease or renal failure have a lot of
