The macula densa is/are: present in the renal medulla dense tissue present in the outer layer of the kidney cells present in the DCT and collecting tubules present in blood capillaries.
Which of the following is an example of autoregulation of kidney function? a. The RAAS regulates Na1 by secreting renin when blood pressure or blood volume decreases. b. The ADH system regulates water balance by decreasing water reabsorption and increasing excretion of salt. c. Receptors in the juxtaglomerular apparatus detect a higher salt concentration in the distal convoluted tubule and trigger constriction of the afferent arteriole to reduce glomerular filtration rate. d. ANF is released by the kidney to increase renin release. e. Angiotensin II lowers blood pressure by constricting arterioles.
Which of the following correctly describes a part of kidney function? a. Collecting ducts dilute urine because they are permeable tosalt but not water. b. In the ascending loop of Henle, Na1 and Cl2 move into thetubules because the osmolarity of the filtrate is increased. c. The descending loop of Henle receives filtrate from theascending loop. d. The distal convoluted tubule pumps water into the tubule byactive transport. e. The renal pelvis receives urine from the collecting ducts andcarries it to the ureters.
Kidneys return most of the water and small solutes back to blood by way of ___ . a. glomerular filtration b. tubular reabsorption c. tubular secretion d. both a and b
1. What would be the influence of decreasing reabsorption of sodium on urine volume?
14. What happens to renal clearance ( the ability of the kidney to monitor blood ion levels) if Blood pressure falls? Explain in detail
4: Fanconi syndrome is a disorder where the Proximal convoluted Tubule is impaired and does not reabsorb like it does normally. This can lead to acidosis (high blood acid levels) and polyuria (frequent dilute urination). Explainthe normal way bicarbonate (HCO3-) and Glucose are reabsorbed in the proximal convoluted tubule. Explainwhy not reabsorbing bicarbonate (HCO3-) and Glucose lead to acidosis and polyuria (respectively).
9. Explain the physiological basis for the effect of atrial natriuretic peptide (hormone) on urinary volume output .
6. Explain how the vertical concentration gradient in the medulla and the concentration of vasopressin influences the volume and osmolarity of urine produced.
11. After iltration of blood in renal corpuscle, urine low in nephron is as follows: a. Proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct b. Loop of Henle, proximal convoluted tubule, collecting duct, distal convoluted tubule c. Proximal convoluted tubule, loop of Henle, collecting duct, distal convoluted tubule d. Loop of Henle, peritubular duct, distal convoluted tubule, collecting duct
1. 14. What is a typical volume of urine that would be excreted in a day? Answer
3. Give the 4 factors affecting the urine volume in physiological system. Explain how each factor affects the volume of urine.
