2

Each ovary contains

200,000 follicles

3

Each follicle contains an ____

Oocyte (egg)

4

Each female is born with all the eggs that will ever release

Approximately 400,000 in a lifetime

5

FSH (follicle-stimulating hormone)

When the oocyte matures and responds to FSH which is released by anterior pituitary gland stimulated by the release of GnRF from the hypothalamus

6

Luteinizing Hormone

Which stimulates the process of ovulation

7

Release of an egg

Is called an ovum

8

At end of pregnancy the uterus and placenta prodcues

Prostaglandins that, along with oxytocin, will signal the uterus to contract and labor will begin

9

Corpus Luteum

What is last of follicle after egg has been released which in return secretes progesterone
Embryo to a fetus

10

Ovum if not fertilized

The ovum dies and degenerates

11

Fallopian tubes

Tubes in which the ovum passes through

12

Uterus

Muscular, inverted pearshaped organ that lies between the urinary bladder and the rectum

13

Cervix

Narrowest portion of the cervix that opens into vagina

14

Vagina cavity

Inside is acidic owing to the breakdown of glycogen ( in the vaginal mucosa ) which creates a low pH environment inhibiting growth of bacteria.
This acid harms sperm killing off many because sperm is alkaline in nature.

15

Episiotomy

Incision of the perineum

16

Heart begins to beat on..

The third week after conception

17

Placenta begins to form on the..

The fourth week after conception

18

Placenta

Respiratory gas exchange
Transport nutrients
Excretion of wastes
Transfer of heat
Hormone production
Formation of a barrier

19

Umbilical cord

Contains Wharton jelly which keeps umbilical cord from becoming knotted
Contains one vein and two arteries

20

Umbilical vein

Carries oxygenated blood from placenta to fetus

21

Umbilical arteries

Carries arteriovenous blood to the placenta

22

Fetal lungs

Blood bypasses the lungs until birth because the baby receives oxygen from the placenta

23

Amniotic fluid

Reaches about 1liter by birth
Provides weightless environment

24

4th-8th week of embryonic development is

Critical for embryonic development
Major organs and body systems start to form
Where birth defects are made during the development phase (smoking, drugs, alcohol)

25

Gestational Period

Time it takes for fetus to form and develop which usually takes 38 weeks

26

Uterus changes after conception

From 10ml of fluid in uterus to 5,000ml before conception
Rarely returns to normal size after pregnancy

27

Measuring fundus

Length in centimeters corresponds to length of gestation
Measure from top of pubic bone to top of fundus

28

Uterus enlarges causing

Pressure on the lower end of the intestine and rectum causing constipation

29

Woman's GI tract relaxes due to progesterone causing

Decrease in moving stomach contents causing heartburn and burping

30

Kidney size in woman..

Increase up to 30%
