Function of ovaries

Produce ova and secrete estrogen/progesterone.

Endocrine products of ovaries

Estrogen and progesterone.

Exocrine product of ovaries

Ova (eggs/oocytes).

Function of uterine tubes

Transport oocyte; site of fertilization.

Most common site of fertilization

Ampulla of uterine tube.

Function of fimbriae

Sweep ovulated oocyte into uterine tube.

Function of uterus

Site of implantation and fetal development.

Function of vagina

Copulatory organ, birth canal, menstrual flow passageway.

Function of mammary glands

Produce milk.

PATHWAYS

Pathway of egg from ovary to uterus

Ovary → ovulation → fimbriae → infundibulum → ampulla → isthmus → uterus.

Pathway of sperm from production to exit

Seminiferous tubules → epididymis → ductus deferens → ejaculatory duct → urethra.

Pathway of urine to outside body

Kidney → ureter → bladder → urethra.

Layers of uterus (superficial to deep)

Endometrium → Myometrium → Perimetrium.

Function of endometrium

Site of implantation; responds to hormones.

Layer shed during menstruation

Stratum functionalis.

Layer that regenerates endometrium

Stratum basalis.

Function of myometrium

Thick smooth muscle layer for uterine contractions.

Outer uterine layer

Perimetrium.

Epithelium of vagina

Stratified squamous epithelium.

OVARIAN FOLLICLES

Primordial follicle identifying feature

Very small; near surface of ovary.

Primary follicle cell layer

One layer of cuboidal cells.

Secondary follicle cell layer

Two to three layers of cuboidal cells.

Tertiary follicle identifying feature

Small antrum with multiple cell layers.

Graafian follicle identifying feature

Large antrum; mature follicle.

Function of greater vestibular glands

Secrete lubricating mucus/fluid into lower vagina.

Location of greater vestibular glands

On each side of vaginal opening.

Function of paraurethral glands

Secrete fluid into vestibule.

Location of paraurethral glands

Near external urethral orifice.

Function of testes

Produce sperm and testosterone.

Function of epididymis

Sperm maturation and storage.

Function of ductus deferens

Transports sperm.

Function of urethra

Passageway for semen and urine.

Function of penis

Copulatory organ.

MALE ACCESSORY GLANDS

Function of renal corpuscle

Filtration of plasma.

Function of PCT

Most reabsorption of water, ions, nutrients.

Function of descending limb

Water reabsorption.

Function of ascending limb

Solute reabsorption; little/no water.

Function of collecting duct

ADH-regulated water reabsorption.

Meaning of obligatory water reabsorption

Automatic water movement following solutes.

Meaning of facultative water reabsorption

Hormone-regulated water reabsorpt

Regions of uterine tube

Fimbriae, infundibulum, ampulla, isthmus.

Region above body of uterus

Fundus.

Opening from uterus into cervix
