the oblique path of of the ureter through valve
the wall of the bladder, permits the
junction to act as a ____________ reducing the
bladder as it becomes full
-lined by transitional epithelium
-Composed mostly of smooth muscle tissue
Urinary bladder structure
Parasympathic involuntary
-can distend considerably
-reservoir for urine before it leaves the body
Function
-aided by the urethra, expels urine from the body
-small tube lined with mucous membranes that extends from the floor of the bladder
to the exterior of the body
Urethra
- Smooth muscles parasympathetic Involuntary
-
3 cm long

-meatus is in the vestibule
20 cm
- passes through the prostate
How long is the urethra in males
-enters base of the penis
-meatus is at the end of the penis
as the bladder volume increases, micturition contractions (of the detrusor muscles)
increase and the internal urethral sphincter relaxes.
micturition
-smooth muscle parasympathetic involuntary
-urge to urinate comes with micturition contractions
the external urethral sphincter muscle is Voluntary
under __________ control control skeletal
muscle
Micturition Also called urination, is a mechanism for, is a mechanism for voiding the bladder

two major parts of nephrons
-tubules
nephrons are connected to the collecting ducts
renal corpuscle glomerulus and glomerular capsule
cup shaped mouth of nephron
Glomerular capsule -collets filtrate
-covers glomerulus- podocytes
