1. Ch 9 Life Stages (vocabulary 16)
Sperm -Fetus
Testes -Placenta
Ovum -Birth
Uterus -Infancy -Childhood
Menstruation -Adolescence - Puberty
Pregnancy -Adulthood -Grief
Embryo

2. Sec 1 Male Reproduction Sperm-male sex cell
Testes- producers of sex cell
Testosterone-male hormone
Scrotum- sac protecting, cooling testes
Epididymis-storage for sperm along testes
Penis-exit from the body for urine, sperm
Prostate Gland-aids in fluid production for sperm

3. Male Reproduction System
Problems
Swelling, pain, rash
Jock itch, STD, Hernia, Undescended testicle, UTI, Testicular cancer, torsion, Prostate enlargement
Care for System:
Bathe, clean dry clothing
Protective gear
Regular Dr. visit
Abstinence

4. Female Reproduction -2 Ovum-female sex cell
Uterus-muscle that will protect fetus
Fallopian Tube-pathway for egg to travel
Endometrium-lining of uterus shed monthly
Cervix-opening to the uterus
Vagina-exit from the body for urine, blood flow
Estrogen- female hormone

5. Female reproduction cycle
Ovulation- is the monthly release of an ovum from an ovary for potential fertilization. If unfertilized the ovum will be eliminated from the body with the monthly uterine lining being shed.
Menstruation- monthly cycle for ovum to travel the fallopian tube and exit the body
Approx 28 days cycle
1-5 uterine lining sheds
1-13 ovum matures in ovary releases day 14
15-28 travels F.T. to uterus: repeat cycle

6. Female reproductive care
Report self exam of lumps, bumps, pain
UTI, endometriosis, STD’s, toxic shock, Cervical cancer
Bathe, dry clothing,
Routine Dr. visit
Abstinence

7. Pregnancy and Birth- 3
Fertilization is the time at which the MALE SEX cell “sperm” penetrate the FEMALE SEX cell “egg” together they form a New cell.
This new cell will travel down the fallopian tube and implant in the uterus.
The uterus is a muscular organ that will stretch in size and nourish the embryo.
This whole process is called: PREGNANCY
EMBRYO < 8 WEEKS
FETUS > 9+ WEEK
Full term wks

8. Pregnancy and Birth
Placenta is the organ that grows and develops to nourish the fetus and eliminate waste from the fetus.
Physical changes in female body: hormones, breast enlargement, uterus stretches, swelling in extremities
Emotional Changes can occur as these hormones are released.

9. Trimester Development
1st= 12 weeks, 3 mos
Fertilization
Heart form 4th wk
Brain and spine develop
Extremities develop
Brain wave detection
2nd =13-24 weeks, 4-6mos
Development 3x in size by end of week 24 compared to week 12
Mother feels movement
3rd = 25=40 week, 7-9 mos
Muscle and organ develop
Practice breathing
Ready for life outside womb

10. Birth Process Uterus contracts forcing baby out of the body.
Labor- time of contraction until birth completed
Stage 1= contraction until cervix opens for head
Stage 2 =cervix open, baby delivered
Stage 3 = delivery of placenta
Caesarean Section = incision in uterine muscle to remove fetus thru abdomen

11. Growing & Changing Infant- newborn Early childhood-1 to 3
Middle childhood 4-6
Late childhood 7-11
Adolescences (maturity)
Adulthood- early, middle and late
Senior – legacy

12. Grief
1. Denial
2. Anger
3. Bargaining
4. Despair
5. Acceptance
