sterile, more dense than water, smells slightly, contains ammonia
What is the gravity of normal urine?
A noninvasvive treatment of kidney stones is
Why is the bladder able to expand?
It has transitional epithelium
How much urine is the bladder usually full with?
The voluntary sphincter associated with the uretha is the...
external uretha sphincter
Describe 4 symptoms of a typical urinary infection
dysuria, urgency, frequency, cloudy urine
What is the enlargement of the prostate gland called?
How many liters of blood plasma does the kidney process in 24 hrs?
Name the 4 major roles of the kidney
Rid of nitrogenus waste, maintain water and electrolyte balance, manage pH of blood
How much of a healthy young adult weight is water weight?
The hormone that acts on the kidney to regulate sodium ion in the EFC is what?
What percent of sodium is reabsorbed by the proximal convoluted tubule?
What is a polycystic kidney condition?
degenerative, blisters or sacs with urine
What is the average output of urine per day for adults?
What is the most common urinary tract infection?
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
How does high pressure condition aid its function of filtrate formation?
leaves proteins and sugars
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
