The triangular region of the bladder that is outlined by two openings of the urter and uretha is called...
Name the 4 functions of the kidney
make urine, convert vitamin D 2 arrive form, dispose waste, regulate blood&volume
Provide the pathway of the arterial blood supply through the kidney
renal artery-segmental-lobular-interlobular-dicutate-interlobular-afferent artiel-glomulus-efferent-peritebral-interlobular-articulate-interior vena cava-renal vein
Give 4 characteristics of normal urine
sterile, more dense than water, smells slightly, contains ammonia
Name the 4 major roles of the kidney
Rid of nitrogenus waste, maintain water and electrolyte balance, manage pH of blood
Name the functions of the bladder, uretha, renal artery, and ureter
Stores Urine- Bladder
Transport urine to body exterior and is shorter in females- uretha
Transport arterial blood to kidney- renal artery
Transport urine to the urinary bladder- ureter
Describe these terms: cortex, medulla, calyx, renal capsule, renal column and renal pelvis
Renal capsule- smooth membrane clinging tightly to the kidney surface
Medulla- portion of kidney containing mostly collecting ducts
Cortex- portion of the kidney containing the bulk of the nephron structures and superficial region of kidney tissue
Renal pelvis- basinlike area of the kidney, continuous w/ ureter
Calyx- an extension of the pelvis that encircles the apex of a pyramid
Renal column- area of cortexlike tissue running between the medullary pyramids
Describe these 4 parts: glomulus, proximal convuluted tubule, collective duct, parietal capillaries, and glomerus
Glomulus- site of filtration
Proximal convuluted tubule- primary site of tubular reabsorption
Collective duct- structure that conveys the filtered urine to the renal pelvis
Parietal capillaries- blood supply that directly receives substances from the tubular cells
Glomerus- inner membrane that forms part of the filtration membrane
Why is the glomerus such a high pressure capillary bed?
Blood that enters into a longer tube, and as it goes down, tube gets smaller, creating high pressure
What structural modification of certain tubule cells enhance their ability to reabsorb substances from the filtrate?
Trace the anatomical pathway of a creatinine molecule from the glomular capsule to the urethra
glomerular capsule-proximial convuluted tuble-Loop of Henli-ducts- renal cortex- medullary pyramid- calyces- renal pelvis- ureter- bladder
List 3 substances that are absent from the filtrate and urine of healthy adults
blood, proteins, sugars, bile
List 2 substances that are routinely found in filtrate but not in urine product
amino acids and glucose
How does starvation influence urine ph?
urine becomes acidic because your body is breaking down amino acids
State these abnormal urine conditions: blood in urine, hemolytic anemia, eating too much candy in one sitting, pregnancy, starvation, urinary tract infection
blood in urine- hematuria
hemolytic anemia- hemoglobinuria
Too much candy in one sitting- glycosuria
Urinary Tract infection- pyuria
