Document Summary
Female urethra (4 cm): embedded within the anterior wall of the vagina. Small distance to bladder is reason why urinary infection is more common in f. Paraurethral glands: constantly keep urethra moist and alter ph. Testes: 2 egg shaped organs, held within scrotum (skin sac) Glands produce fluid part of the semen testis produces sperm only. M testes develop near kidneys and then leave abdominal cavity (cooler temperature is required to function) Vas (ductus) deferens: begins after the tail of the epididymis; delivers sperm to prostatic urethra. Epididymis (6m, highly coiled) segments: head (on top of testes), body (posterior to testes), and tail (end) Efferent ductules short ducts that drain sperm produced in the seminiferous tubules. Rete testes complex network of ducts on the posterior testes that drains into the epididymis. Function: maturation of sperm; 64 days to travel ~6 m length. Spermatic cord: vas deferens, blood vessels, nerves and lymphatic vessels; same muscular layers as testes.
