Anatomy 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_forwardRenal Physiology (human) The foot processes of podocytes surround the peritubular capillaries of both cortical and juxtamedullary nephrons. Vasa recta are long, straight blood vessels associated with juxtamedullary nephrons. Canagliflozin is a therapeutic drug that acts on the collecting duct to decrease glucose reabsorption.arrow_forwardPart of Structure of the wall Role in (cells, their appearance, formation arrangement) the nephrone of urinearrow_forward
- Which of the following is NOT a function of the kidneysarrow_forwardOnce micturition reflex is initiated, the individual will not be able to control the urge to urinate and sphincters cannot be willfully contracted. True or false and whyarrow_forwardKIDNEY FUNCTION IN REGULATION OF RENAL BLOOD FLOW, FLUIDS VOLUME AND REGULATION OF ENDOCRINEarrow_forward
- Characteristics and dietary management of Renal calculiarrow_forwardphysiology of micturition and the use of sphincters. (simple and easy and in own words)arrow_forwardTo say that your body has somatic control over your external urethral sphincter that means you can ________ control that sphincter.arrow_forward
- Renal tubules cannot reabsorb HCO3–; yet HCO3–concentration in the tubular fluid falls while in the blood plasma itrises. Explain this apparent contradiction.arrow_forwardWhich glomerular arteriole is larger, and why? the efferent, because it increases hydrostatic pressure in the glomerulus the efferent, because it increases colloid oncotic pressure in the glomerulus the afferent, because it increases hydrostatic pressure in the glomerulus the afferent, because it increases colloid oncotic pressure in the glomerulusarrow_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
