B2 - female

Question 1

female reproductive system

Answer 1

-make eggs
-fertilize
-place for fetus
-labour
- female sex hormones
(EFFLS)

Question 2

flow phase

Answer 2

0-5
high FSH levels = stimulating follicle development.
low E & P so linings sheds

Question 3

follicular phase

Answer 3

6-13
FSH stimulates follicles to grow and produce E
which thickens the endometrium. FSH stops so other follicles dont grow (neg feedback)

Question 4

3. ovulatory phase

Answer 4

day 14
LH increase triggers ovulation.
Estrogen levels peak, and progesterone begins to rise.
Mature follicle ruptures

Question 5

4. luteal phase

Answer 5

Day 15-28
Corpus luteum makes E & P
P maintains endometrium and stops FSH & LH.
no fertilization = E & P drop

Question 6

regulation of reproductive hormone

Answer 6

hypo makes GNRH causing ant pit to make FSH & LH, causing growing follicles and corpus luteum

Question 7

regulation of reproductive hormone NEG FEEDBACK

Answer 7

stop growing follicle = estrogen
stop corpus luteum = Progesterone

Question 8

stimulation of egg dev

Answer 8

FSH

Question 9

inhibition of ovulation

Answer 9

progesterone

Question 10

dev of secondary sex characterisitics

Answer 10

estrogen

Question 11

stimulation of ovulation & corpus luteum

Answer 11

LH

Question 12

Fallopian tubes (oviducts)

Answer 12

carries cell + fertilization

Question 13

uterus

Answer 13

fetal devleopment

Question 14

cervix

Answer 14

Glands secrete mucus.
Blocks bacteria.
Helps sperm move.

Question 15

follicles

Answer 15

egg development (oogenesis).
matures n releases an egg during ovulation.
Fimbriae move the egg to the fallopian tube.

Question 16

follicles produce

Answer 16

Specialized tissue produces estrogen.

Question 17

corpus luteum

Answer 17

-Forms from follicle after ovulation.
-Produces pregnancy hormones (progesterone & estrogen).
-Breaks down after 10 days if no pregnancy occurs.

Question 18

FSH

Answer 18

-stimulates follicular growth in ovaries
- releases estrogen

Question 19

LH

Answer 19

surge causes ovulation (egg release)
- results in the formation of corpus luteum

Question 20

estrogen

Answer 20

thickens uterine lining (endometrium)
- slows FSH and LH
- stimulates FSH and LH pre ovulation

Question 21

progesterone

Answer 21

produced by CL after ovulation
-thickens uterine lining
slows FSH and LH

Question 22

Oogenesis (Egg Development)

Answer 22

develops in follicles:
Each month, one follicle matures and releases an egg (ovulation).
Remaining follicle tissue becomes the corpus luteum, which secretes progesterone and estrogen.

Question 23

pathway of a egg

Answer 23

Ovary → Fimbriae → Fallopian Tube → Uterus

Question 24

Granulosa Cells:

Answer 24

Surround and nourish the egg.

Question 25

oocyte

Answer 25

immature egg in follicle
