Acidic
222
Acidic or alkaline: Adolescents
Alkaline more prone to infection(STD’s)
223
Mons pubis:
fatty area overlying pubic symphys
224
Labia majora
hair-covered, fatty skin folds ○Counterpart of male scrotum
225
Labia minora
skin folds lying within labia majora ○Counterpart of male spongy urethra of the penis
226
Greater vestibular glands
release mucus into vestibule for lubrication ○Counterpart of male bulbo-urethral glands
227
Clitoris
structure composed largely of erectile tissue ○Counterpart to the male penis
228
Ovarian Cycle
prepares ovum (mature egg)
229
Uterine Cycle
prepares uterus
230
Ovarian cycle → months
(~28 day) series of events associated with maturation of egg
231
Two consecutive phases; Follicular phase
period of vesicular follicle growth (days 1-14) ●Increased secretion of estrogen - one follicle is selected, point that ovulation occurs (mid cycle) ●Hypothalamus → GnRH (1x/month) → Anterior Pituitary → FSH/LH
232
Two consecutive phases; Luteal phase
period of corpus luteum activity (days 14-28) ●Only 10-15% of women have 28-day cycles (up to 40 or short as 21 days) ○Follicular phase varies, but luteal phase is always 14 days from ovulation to end of cycle
233
Ovulation
ejection of oocyte from ripening follicle
234
Fraternal Twins
not identical; 2 oocytes fertilized by 2 sperms
235
Identical Twins -
1 oocyte fertilized by 1 sperm but early separation of daughter cells
236
Corpus luteum
secretes high levels of progesterone and some estrogen corpus luteum produces hormones that sustain pregnancy until placenta is ready to take over → at about 3 months
237
Days 0-4: Menstrual Phase
endometrium detaches & sheds (bleeding); low levels of hormones
238
Days 5-14: Proliferative (preovulatory) Phase
rising levels of estrogen; endometrium rebuilds; ovulation occurs at the end of this stage
239
Days 15-28: Secretory (postovulatory) Phase →
most constant timewise; endometrium prepares for embryo implant; a cervical plug forms to block sperm, pathogens, foreign materials, etc; 1.if fertilization does not occur the corpus luteum degenerates toward the end of this phase
240
Estrogens
Promote oogenesis (development of ovum) and follicle growth in ovary ○Anabolic effects on female reproductive tract Induce secondary sex characteristics ■Growth of breasts ■Increased deposit of subcutaneous fat (hips & breasts) ■Widening and lightening of pelvis
241
Progesterone:
Works with estrogen to establish and regulate uterine cycle ■Promotes changes in cervical mucus ■Effects of placental progesterone during pregnancy ●Inhibits uterine motility ●Helps prepare breasts for lactation
242
Fibroelastic adventitia
Outer
243
Smooth muscle muscularis
Middle
244
Stratified squamous mucosa with rugae
inner ■Withstand friction
245
concurrent: prepares ovum (mature egg)
246
Uterine Cycle →
prepares uterus
247
Days 0-4: Menstrual Phase →
endometrium detaches & sheds (bleeding); low levels of hormones
248
Days 5-14: Proliferative (preovulatory) Phase →
rising levels of estrogen; endometrium rebuilds; ovulation occurs at the end of this stage
249
Days 15-28: Secretory (postovulatory) Phase →
most constant timewise; endometrium prepares for embryo implant; a cervical plug forms to block sperm, pathogens, foreign materials, etc; 1.if fertilization does not occur the corpus luteum degenerates toward the end of this phase

251
T/F: An alkaline fluid that neutralizes the acidity of male urethra and female vagina and enhances motility
T
252
What is seman made of?
Contains: ○Fructose → for ATP production ○Prostaglandins → viscosity of mucus ○Hormones → enhance sperm motility ○Antibiotics → destroy some bacteria ○Clotting factors → causes sperm to stick to walls of vagina
253
Static test
ERV, IRV, RV, TV, VC
254
Dynamic
forced expiratory volume, Forced expiratory volume in 1 second, Forced Vital Capacity
255
Role of the Renal Cortex?
Outer most layer -received >90% of blood that enters the kidneys
256
Role of the Renal Medulla
Secretes urine into a sac-like tubules
257
Role of the Renal Pelvis
Peristalsis to move urine out into the ureter
258
Role of the Major Calyx
Collects urine form the minor calves and then empty’s urine into Renal Pelvis
259
Minor Calyx role
Drain the pyramids at papillae
