Concerning development of the urinary system O a. the ureteric bud is a diverticulum of the urogenital sinus O b. the kidneys and adrenal glands form together within the pelvis and migrate superiorly as a unit O c. "horseshoe" kidneys are usually trapped during their ascent by the gonadal arteries d. a urachal fistula connects the rectum and the urinary bladder e. none of the above is true

The voiding reflex allows the sensation of the urge to urinated but prevents uncontrol urination ty Select All the correct answers. stimulating parasympathetic stimulation of the detrusor muscle inhibiting parasympathetic stimulation of the detrusor muscle ) stimulating somatic nerves to the external urethral sphincter inhibiting somatic nerves to the external urethral sphincter inhibiting sympathetic stimulation of the internal urethral sphincter

1. The location of the kidneys in the body is best described as being: In the pelvic cavity In the mediastinum retroperitoneal In the thoracic cavity 2. Place the structures of the renal tubule in the correct order from the start of filtration to completed urine in the collecting duct. descending (proximal) loop of Henle proximal convoluted tubule (PCT) distal convoluted tubule ascending (distal) loop of Henle Bowman's capsule 3. Place the structures of the blood flow in the nephron in the correct order. glomerulus afferent arteriole peritubular capillaries efferent arteriole cortical radiate veins

Which of the following is TRUE concerning renal handling of potassium? a. A high potassium meal will cause enhanced basolateral uptake via sodium-potassium pumps b. Most potassium reabsorption occurs at the distal tubules c. Aldosterone enhances potassium reabsorption at the proximal tubule d. Potassium is not filtered, so urinary excretion of potassium will only occur by stimulating potassium secretion e. Decreased extracellular potassium concentration increases aldosterone production and thereby reduces potassium secretion

The following structures articulate with the kidneys at the hilum: D - major calyx B - renal veins A and B A - renal arteries A, B, and C C - ureter A, B, C, and D

Which of the following relates to polycystic kidney disease? Select one: A. It affects infants and children. B. The kidneys are displaced and the ureters are twisted. C. It affects the left or right kidney. D. It results in chronic renal failure. E. The disease is reversible. O O O с

Each renal pyramid and its surrounding renal columns constitutes one of seven to eight _________ of a kidney   a. lobes   b. capsules   c. tubules   d. none of the above

Which of the following is/are true concerning kidney structure?   a. The 'hilum' is the concave part of the kidney through which everything entering or leaving the kidney goes   b. The kidney is surrounded by a thin connective tissue capsule   c. Urine collects in the renal sinus   d. The renal medulla contains the renal corpuscles   e. Each kidney contains about a million nephrons

Urinary filtration occurs at   a. Proximal convoluted tubule b. Collecting duct c. Glomerulus d. Loop of Henle

Maria is 8 months pregnant. When she goes to her doctor for her checkup, the nurse takes her blood pressure. It is unusually high: 200/100 mm Hg. The nurse also collects a urine sample and detects elevated levels of protein in her urine.What do you think has happened to her urine production? (Consider the pressures involved in determining net filtration pressure and osmotic force generated by solutes in the filtrate.) a. Urine production has stayed the same. b. Urine production has increased. c. Urine production has decreased. d. It is not possible to predict the effect on urine production.
