A) relaxation of the detrusor muscle and contraction of the internal urethral sphincter.
B) relaxation of both the detrusor muscle and the internal urethral sphincter.
C) contraction of both the detrusor muscle and the internal urethral sphincter.
D) contraction of the detrusor muscle and relaxation of the internal urethral sphincter.
The primary purpose of the collecting system is to (a) transport urine from the bladder to the urethra. (b) selectively reabsorb sodium ions from tubular fluid. (c) transport urine from the renal pelvis to the ureters. (d) make final adjustments to the osmotic concentration and volume of urine.
