Please explain this in the most simple way.
Explain the kidney's role in water conservation. How much water is reabsorbed (by following other reabsorbed substances) by osmosis? How much water does the nephron loop and collecting duct have to be "tricked" into reabsorbing? How exactly does that work? How do hormones control this process? What effect does alcohol have?
Describe the micturition reflex. How is voluntary control ofmicturition accomplished?
Describe how the central nervous system is involved in the micturition reflex.

Distal convoluted tubule?arrow_forwardDescribe the functions of the urinary system. Identify the 4 organs of the urinary system. What is a nephron? Describe the gross anatomy of the kidneys Trace the blood flow (listed vessels only) from Abdominal Aorta to Inferior Vena cava. Describe the structure of the Glomerulus (Renal Corpuscle). Trace the flow of filtrate through the nephron. Identify which nephron parts are in the cortex and which are in the medulla of kidney. Describe the anatomy (layers and tissues) and the functions of the ureter, urinary bladder, and the urethra. Describe the following nephron functions and identify the specific nephron structures where these processes occur. Filtration – Reabsorption – Secretion - Identify the specific structure in the nephron and the process that occurs for each listed substance: Process: filtered, not filtered, reabsorbed, secreted. Substances = water, Na+, K+, H+, Bicarbonate (HCO3-), Cl-, Ca2+, urea, ammonia (NH3 or NH4+), glucose, protein, amino…arrow_forward+ 1. Summarize the role of the kidneys in each of the following functions: Adjusting blood volume (and so blood pressure) and the volume of interstitial fluid and lymph Regulating calcium ion levels Stimulating the production of red blood cells (erythropoiesis) Regulating blood pressure Regulating blood glucose levels Adjusting the pH of body fluids Regulating the blood Na* and K levels Regulating blood Cl levels Getting rid of wastes such as urea, ammonia, uric acid, creatinine, urobilin from breakdown of hemoglobin, foreign substances such as drugs and environmental toxinsarrow_forward
- With respect to the renal system, what is reabsorption? Why is it important? Please mention exactly what impact reabsorption has on the body when it occurs in the different parts of the nephron for the different ions like: HCO3, H2O, K+, NaCl, Ca++ and Nutrients and water, etc.arrow_forwardWhat steps lead to micturition? At what point does the reflex overcome conscious control?arrow_forwardAldosterone affects sodium balance by impacting sodium reabsorption in the distal nephron. If MAP and/or GFR falls, how will this system function? Increased levels of aldosterone add epithelial sodium channels (ENaCs) to the luminal membrane of the collecting duct. Increased levels of aldosterone remove epithelial sodium channels (ENaCs) from the luminal membrane of the collecting duct. Decreased levels of aldosterone allow increased expression of epithelial sodium channels (ENaCs) in the collecting duct. O Decreased levels of aldosterone decrease expression of epithelial sodium channels (ENaCs) in the collecting duct.arrow_forward
