What are the 3 erectile tissues? Function?

The two corpora cavernosa and the single corpus spongiosum. These 3 have vascular sinuses that fill with blood during erection.

Why would a reproductive tract infection be more likely to lead to an inflammation of the peritoneum in a female than in a male?

Because the female reproductive duct system is open to the peritoneum whereas the male duct system is not

What layer of the uterus would contain the most actin?

Myometrium

The term ampulla refers to which structures in bth the male and female reproductive systems?

Ductus deferens (proximal end) and uterine tube (distal end)

Trace the path of a single sperm from the site of its production to the site of fertilization

Seminiferous tubule > epididymis > ductus deferens > ejaculatory duct > prostatic urethra > membranous urethra > penile urethra > vagina > external os > cervical canal > internal os > uterine cavity > fallopian tube > ampulla of fallopian tube

What accessory organs contribute to the composition of semen? Which makes up the most?

-Seminal vesicles, prostate glands, and bulbourethral glands

- Seminal vesicles. They produce alkaline fluid which makes up 60% of semen. (Prostate gland is 30% and bulbourethral gland is the least)

What is circumcision?

Removes the prepuce (foreskin) of the glans penis

Explain the mechanism that draws an ovulated oocyte into the lumen of a uterine tube.

The sweeping of the cilia of fimbriae creates a current of peritoneal fluid that draws the secondary oocyte into the uterine tube
