ANTOMY AND PHYSIOLOGY
- Fatty tissue holds the kidneys in place. Extremely rapid weight loss may cause this tissue to shrink so that the kidneys slip from their normal position. On rare occasions, the slippage can put a kink in one or both ureters and block urine flow. Suggest what might then happen to the kidneys.arrow_forwardphysiology of micturition and the use of sphincters. (simple and easy and in own words) dot pointsarrow_forwardGlomerular colloid osmotic pressure is greater in the afferent end than in the efferent end of the glomerular capillary regardless of the change in filtration fraction. True or false and why.arrow_forward
- How the kidneys metabolize carbohydrates, lipids, ans proteins and the effects that these three micromolecules have on renal functions. Examine how the gross and histological structure of the kidney facilitates urine production during 1) glomerular filtration, 2) tubular reabsorption, and 3) tubular secretion.arrow_forwardThe fenestrations of the glomerular capillaries allow all blood components except blood cells to pass through True Falsearrow_forwardoverall structure of the kidney and what function each part hasarrow_forward
- Differences between oesophagus and ureterarrow_forwardThe urine transport from the kidney to the urinary bladder calledarrow_forwardIs this statement true or false: The juxtagomerular apparatus also pays a role in controlling the net glomerular filtration rate. If the GFR is high macula densa cells detect increase blood pressure. These cells respond by decreasing releasing of water which results in vasoconstriction of afferent. This decreases the GFR.arrow_forward
