The testes are where sperm are manufactured in the scrotum. The epididymis is a tortuously coiled structure topping the testis, and it receives immature sperm from the testis and stores it for several days. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. When ejaculation occurs, rhythmic muscle movements propel the sperm forward.
If the child’s urine output decreases to less than 100ml/24
hr and the creatinine clearance is 69 ml/min, plus an irregular apical pulse
with a diagnosis of acute renal failure, the serum level requires immediate
intervention is a potassium 6.1 mEq/L.
