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

Describe two examples of homeostatic systems in humans The phrase homeostasis originates from the Greek language. “Homeo” defined as “similar” and “stasis” meaning “stable”. Homeostasis is vital for us humans as it maintains equilibrium in the body‚ which may be caused due to extrinsic changes. Homeostasis happens to sustain the bodies activity‚ health and functioning. Homeostasis can occur to organs like skin‚ kidney or liver and it usually contains a system of feedback controls. The body has various

HYPONATRAEMIA IN THE NEUROSURGICAL PATIENT INTRODUCTION Sodium the most abundant electrolyte in the human body‚ and therefore the osmolality of body fluids is strongly dependent on its concentration. Osmolality in turn is important in maintaining homeostasis within the brain. Ironically‚ dysfunction of the brain can cause changes in sodium homeostasis. To avoid neurological deterioration‚ morbidity or mortality the sodium level must be corrected promptly. The two most common causes of hyponatraemia

Both the endocrine and nervous systems are major regulating systems of the body; however‚ the nervous system has been compared to an airmail delivery system and the endocrine system to the pony express. Briefly explain this comparison. The nervous system is a lot more fast acting and more rapid action occurs when compaired to the endocrine and the slow

solute gradient (concentration) in the interstitial space is increased? Explain!!! (3 points) It increases because ADH causes water to move out of urine and the more solute there is the more concentrated the urine. 16. Speculate on ways that desert rats are able to concentrate their urine significantly more than humans? (Think: Hormones) (2 points) They probably produce more ADH to get all the water possible from the urine as there is not a lot of water in the desert. 17. What would be a reasonable
