urinary
Stack #181175
| Question | Answer |
|---|---|
| renin | produced in kidney, increases blood pressure |
| urinary system regulates pH by | excretion of H+ |
| kidney in front of or behind peritoneum | behind. (reteroperitoneum) |
| left kidney located between __ ribs | T12-L2 |
| right kidney located between _ ribs | L1-L3 |
| renal fascia | connective tissue which wraps around kidney and adrenal gland separately. |
| ___ absorb shock for protection of kidney | perirenal fat |
| lobe of a kidney | medulla, cortex, 1/2 renal columns |
| lobule | space between adjacent interlobular arteries |
| different nephrons converge at | collecting tubule |
| __ and __ not pass through filters in renal corpuscle | protein and RBC |
| glomeruous fed by ___, drained by__ | arteriole (interlobular), arteriole |
| macrophages that keep filters clean called | mesangial cells. |
| in bowman's space __ is found | filterate |
| How blood filtered? | 1. fused basal lamina 2. fenestrated endothelial 3. podocytes (visceral layer of glomerular) |
| what is filteration diaphragm | thin structure between filteration slits |
| proximal convoluted tubule has __ cells | epithelial, simple cuboidal. |
| water reabsorption in loop of henle mainly occurs in __ and its caused by | thin descending, thin ascending, concentrated interstitial fluid generated by active transporters (pump out Na, Cl) at the thick ascending limb. |
| ___ becomes afferent arteriole | interlobular artery |
| ___ in ___ monitors electrolyte concentration in the tubular fluid. it also __ | macula densa, distal convoluted tubule, stimulate juxtaglomerular cells |
| juxtaglomerular cells present in , secrete ___ | smooth muscle of afferent arteriole, renin |
| JGA is | mascula densa + juxtaglomerular cells |
| JGA function | increase filteration rate, raise BP, in response to conc't urine. |
| Ureter histology: | transitional epithelium, lamina propria, smooth muscle, connective tissue (note lacks submucosal layer) |
| __ of ureter responsible of contraction (peristalsis) of the tube, and it results in _ | smooth muscle, milk urine of renal pelvis into the urinary bladder. |
| sites of urinary constriction | 1. ureteropelvic junction 2. crossing of the iliac vessel 3. ureterovesical junction |
| ___ epitithelium of ureter allow __ | transitional epithelium, strectching of ureter. |
| Urinary bladder histology : | transitional epith, lamina propria, submucosa, detrusor muscle. (typical) |
| ___ of bladder allows discharge of urine from the bladder | internal urethral sphincter. |
| urethra histology: | stratified squamous epithelium, lamina propria, smooth muscle. |
| aldosterone, ADH effects | increase BP by increasing water, Na+ retention. secretes K+ out to the urinary tract. |
| aldosterone effects which region | distal convoluted tubule |
| ADH effects which region | collecting tubule and ducts. |
| each lobe dumps urine into ___ which then takes urine to __ eventually to __ | renal papilla, calyx, pelvis |
| renal artery/vein gives a rise to | segmental artery/vein |
| __ forms the visceral layer of renal corpus. | podocyte |
| __ forms the parietal layer of renal corpuscle | bowman's capsule |
| __ controls movement of urine out of urinary bladder | internal urethral sphincter |
| __ controls movement of urine out of urethra | external urethral sphincter |
| urethra has __ as epithelium | stratified squamous |
| thin ascending/descending tube of loop of Henle has __ epithelium | simple squamous |
