5 functions of the kidney excrete toxins and nitrogenous wastes; regulate chemical levels; maintain water balance; regulate blood pressure; stimulate RBC production and maturation
three processes of urine formation filtration, reabsorption, secretion
this process of urine formation takes place in the renal corpuscles; glomerular blood pressure forces water and dissolved substances out of the glomeruli into bowman's capsule filtration
this process of urine formation involves the muovement of substances out of renal tubules into blood reabsorption
this process of urine formation involves the movement of substances into urine in the distal and collecting tubules secretion

smooth triangular area on the wall of the urinary bladder trigone
high levels of nitrogen-containing waste products in the blood uremia or uremic poisoning
essential reproduction organs of the male reproductive system testes
accessory organs of the male reproductive system ducts, sex glands, external genitals
these accessory organs of the male reproductive system are passageways that carry sperm from the testes to the exterior ducts
these accessory organs of the male reproductive system produce protective and nutrient solutions for sperm sex glands
the process of sperm production spermatogenesis
this hormone produced by the testes masculinizes and promotes the development of male accessory organs testosterone
single coiled tube about 6m in length that lies along the top and behind the testis in the scrotum epididymus
receives sperm from the epididymis and transports them from the scrotal sac through the abdominal cavity ductus (vas) deferens
mixture of sperm and accessory sex glands semen
this accessory organ of the male reproductive system is shaped like a doghnut and is located below the bladder prostate
these accessory organs of the male reproductive system are pea shaped glands that secrete mucous bulbourethral (cowper's) glands
surgical removal of foreskin circumcision
two dorsal columns of erectile tissue corpora cavernosa
the ventral column of erectile tissue surrounding the urethra corpus spongiosum
essential organs of the female reproductive system ovaries (gonads)
accessory organs of the female reproductive system ducts, sex glands, external genitals
this hormone produced by the ovaries causes develpment and maintenance of secondary sex characteristics estrogen
approximately how many ovarian follicles does a female have at birth? 1 million
approximately how many primary ovarian follicles does a female have at puberty? 400,000
this structure forms from the follicle after ovulation corpus luteum
the meiotic cell division that produces daughter cells with equal chromosome numbers but unequal cytoplasm oogenesis
the cells of the ovaries that produce estrogen granulosa ceels
the structure that produces progesterone following ovulation corpus luteum
the muscle layer of the uterus myometrium
the layer of the uterus lost in menstruation endometrium
end of repetetive menstrual cycles which occurs at approximately 45-50 years of age menopause
glands of the vagina that secrete lubricating fluid bartholin's glands
components of the vulva mons pubis, clitoris, orifice of urethra, bartholin's gland, vagina, labia minora, labia majora, and hymen
area between the vaginal opening and anus perineum
surgical cut to perineum during childbirth episiotomy
length of average menstrual cycle 28 days
the phase of the menstrual cycle during which the endomentrium is shed menses
the phase of the menstrual cycle between menses and secretory phase proliferative phase
the phase of the menstrual cycle between ovulation and the beginning of the next menses secretory phase
specialized structure on the sperm containing enzymes that break down the covering of the ovum to allow entry acrosome
absence of normal menstruation amenorrhea
cavity antrum
the pigmented ring around the nipple areola
noncancerous enlargement of the prostate benign prostatic hypertrophy
surgical removal of the foreskin circumcision
