ureters one originationg from each kidney, transport urine from the what to where |
the renal pelvis to bladder |
|
yodrostatic pressure and gravity assist with urine flow, while |
peristaltic contractions of smooth muscle in the ureter walls push urine towards bladder. |
|
the ureters are approximately how long |
10 to 12 inches long |
|
both ureters attach to where on the bladder |
posterior base |
|
as bladder fills, what prevents backlfow |
the opening of the ureter closes |
|
the ureters are lined by what |
mucous membrane containing transitional epithelium |
|
mucous membrane allows ureters to do what |
stretch with variable volume of urine |
|
the secreted mucus protects the epithelium from coming into direct contact with |
urine |
|
bladder is located |
posterior to the pubic symphysis in the pelvic cavity |
|
because the uterus also occupies space in the pelvic cavity, the female bladder is slightly |
small than males |
|
folds of bladder |
rugae |
|
folds in mucosal layer of bladder and the presence of transitional epithelium provide for what |
bladders distensibility |
|
at the base of the bladder, there is a |
triangular shaped area called the rigone |
|
the three apices of teh triangle are the |
openings of the two ureters and urethra |
|
the what surrounds the mucosal layer of bladder |
detrusor muscle |
|
detrusor muscle consists of three layers of muscle fibers |
inner longitudinal, middle circular, outer longitudinal |
|
three layers of detrusor muscle function is to |
assist with the emptying of bladder |
|
superficial layer of the bladder are the |
adventitia and serosa |
|
the adventitia is a layer of |
areolar connective tissue located on the posterior and inferior surfaces and is continuos with the ureters |
|
the serosal is the layer of |
visceral peritoneum on the usperiour surface |
|
there are two what that control urine realease from bladder |
sphincters |
|
sphincters names |
internal and external urethral sphincters |
|
the circular fibers around the opening of the urethra form the |
internal sphincter |
|
deep skeletal muscles of the perineum form the |
external uretral sphincter |
|
also called urination or voiding |
micturition |
|
when volume exceeds.... the distension of bladder triggers stretch receptors that convey impulses to the micturition center in the sacral spinal cord |
200 to 400 ml |
|
urethra of males and females length |
men 20 cm, women 4 cm |
|
three regions of male urethra |
prostatic, membranous, spongy |
|
location of female urethra |
between clitoris and vaginal opening |
|
barriers for compartments of holding water in body are |
plasma membrane of cells and blood vessel walls |
|
two thrids of total fluid in body is |
intracellular |
|
exteracellular environment can be divided into a number of campartments. main compartment is |
interstitial compartment |
|
interstitial compartment is |
fluid in tissues and bathing cells |
|
other extracellular fluids are the |
plasma, urine, csf, aueous, and vitreous humors, endolymph, perilu,ph, and lymphatic, synovial, pleural, pericardial, and peritoneal fluids |
