Answer 35

Narrow end of uterus; allow flow in/out of uterus

Question 36

Endometrium

Answer 36

Mucosal lining of uterus Made of functional layer (stratum functionalis) This is the layer that gets shed And deep basal layer (Stratum basalis) forms new functional layer after menstruation

Question 37

Uterine (Fallopian) tubes

Answer 37

Transport of egg and fertilization site

Question 38

Fimbriae

Answer 38

distal end of fallopian tube; "connect" the gonad (ovary) with uterine tube; catch egg when released by ovaries and move it through the tube

Question 39

Question 49

Menstrual

Answer 49

Functional layer of endometrium shed Before ovulation- follicular phase

Proliferative

Answer 50

Functional layer of endometrium is rebuilt due to estrogen influence Estrogen also causes spike in LH and FSH in this phase Before ovulation- follicular phase

Question 51

Secretory

Answer 51

Immediately after ovulation under influence of progesterone, enrichment of blood supply and glandular secretion of nutrients prepare endometrium to receive embryo Luteal phase
