Urinary/Reproductive
| Question | Answer |
|---|---|
| kidneys function | filter blood from renal arteries; produce urine as waste |
| ureters | transmits urine to bladder |
| urethra | through which urine passes out of body |
| renal capsule | thin but tough covering for kidneys |
| cortex | outer portion of kidney |
| medulla | inner portion of kidney; made of segments: renal pyramids |
| renal pyramids | in medulla; contain collecting ducts that drain urine to minor calyces; pyramids separated by RENAL COLUMNS |
| renal columns | separate renal pyramids in medulla |
| minor calyces converge --> ____ --> ____ | major calyces --> RENAL PELVIS |
| renal pelvis becomes... | portion of kidney that narrows to become URETER |
| retroperitoneal | position of kidney: within abdominal cavity, posterior to peritoneal cavity |
| males: major structures of pelvic cavity | urinary bladder, prostate, rectum |
| females: structures of pelvic cavity | ovaries, uterine tubes, uterus, vagina, bladder, rectum |
| testes lie within _______ | scrotum |
| scrotum | outside of pelvic cavity behind penis, contain testes |
| vas deferen | tubes connecting testes to rest of male reproductive system by transporting sperm from EPIDIDYMIS --> URETHRA |
| seminal vesicles | paired glands that joins w/ vas deferens --> ejaculatory ducts |
| ejaculatory ducts | composted of VAS DEFERENS & SEMINAL VESICLES; empty into prostate gland |
| prostate gland | to which ejaculatory ducts empties; allows semen to pass into URETHRA |
| urethra's 3 regions | prostatic, membranous, spongy urethra |
| prostatic urethra | as urethra passes through prostate |
| membranous urethra | as urethra passes through muscular floor of pelvis |
| spongy urethra | urethra passes out of pelvis and through penis |
| penis composed of ________ tissues | erectile tissues |
| penis's 3 chambers | 2 corpora cavernosa (paired), corpus spongiosum |
| corpora cavernosa | paired upper chambers of penis; close in contact throughout penis, @ base, diverge to attach to inferior rami |
| corpus spongiosum | 3rd chamber of penis, surround URETHRA when emerges from pelvis --> forms GLANS |
| glans | at bottom/ tip of penis, formed by corpus spongiosum |
| uterine tubes | = fallopian tubes in humans; 2 uterine tubes join to form body of uterus |
| cervix | muscle ring= most inferior portion of uterus |
| vagina | muscular tube that connects uterus to exterior; =birth canal & sex organ |
| labia majora | skin-covered structure surrounding vulva (external genitalia) |
| labia minora | internal of labia majora; merge to form clitoris |
| clitoris | small erectile organ derived from embryological structure w/ penis; formed from labia minora merge |
| external urethra orifice | opening of urethra; posterior to clitoris, anterior to vagina opening |
