Chapter 16 Lessons 2 & 3

-Female Reproductive System

-Male Reproductive System

What do you know about the female reproductive system?

Reproductive Systems – systems responsible for producing offspring

Internal Organs

Ovaries- female sex glands

• produce egg(ovum)

• produce estrogen and progesterone

Born about 200,000 during lifetime 400 will mature

uterus

cervix

Fallopian Tubes – pair of tubes fingerlike projections that draw in the ovum

• pathway for egg• carries egg to uterus fertilization takes place 90%

Uterus- pear shaped- egg implants in uterine lining

- fetus grows

Endometrium – lining of uterus

Cervix- opening uterus to vagina

Implantation outside the uterus

Implantation inside Fallopian tube

called tubal pregnancy

1 in 50 pregnancies is

ectopic

Cervix- opening uterus to vagina

COMMON cause of cancer!

Pap smear- test cervical cancer (GYN) once a year

• Vagina- Passageway fromto outside

Menstrual CycleDays 1-8- Menstrual flow

Days 9-13- New egg is maturing- Lining begins to thicken

Day 14- Ovulation – mature egg is released

Days 15-28- Egg travels through fallopian tube toward uterus- Fertilization may occur

Care Female Reproductive System

• Bathe Regularly• Abstinence from sex• Breast self exams and regular medical exams p.

455

Chance of dying from breast cancer is about 1 in 36

Chance of a woman having invasive breast cancer some time during her life is about 1 in 8

Chances are high the disease will touch your life, or the life of someone you know.

Problems of the Female Reproductive System

• Cramps – avoid salt & caffeine light exercise help

• Premenstrual Syndrome (PMS) – causes by hormonal changes anxiety, bloating, depression, fatigue, weight gain exercise can help

• Toxic Shock Syndrome (TSS) – bacterial infection – fever, sunburn like rash, muscle aches- low absorbency tampon- change tampons often

Infertility – cannot reproduce

• Endometriosis - uterine tissue grows into uterus, abdominal cavity, or fallopian tubes

• Vaginitis – bacterial infection (yeast infection)• STI• Ovarian Cysts- fluid filled sacs of ovary• Cancers

Male Reproduction System

• Do Now:• List Secondary Sex Characteristics (changes that

happen to the body during puberty) for either males or females.

Male Puberty • Begins between ages 12-15• Pituitary glands sends hormones to the

testes.• The testes then produce testosterone.

Secondary Sex Characteristics Broadening of shoulders Enlargement of external

organs Development of muscles Longer heavier bonesHair growth Increase in height Deepening of voice Rougher tougher skin

Male Reproductive Organs

External Organs

• Penis • Scrotum – external skin sac

- Hangs from the body hold testicles- Temperature regulation

Male Reproductive SystemInternal Organs

• Testes – 2 small glands (seminiferous tubules)- sperm production- testosterone (hormone)

• Epididymis- sperm mature and are stored

• Vas Deferens- tubes that extend from each epididymis to the urethra

• Seminal Vesicle-first stop fluid

• Prostate Gland- more fluid

- Common site of cancer- Rectal exam after 40/50

• Cowper’s Gland- secrets more fluid-Prepares urethra

• Urethra- exit for semen & urine

Semen – thick fluid containing sperm and other secretions

Care of Male Reproductive Systems

• Regular Check ups (12 to 18 months)

• Bathe regularly – thoroughly clean penis and scrotum

• Protective equipment- cup or supporter

• Self exams – check testicles for signs of cancer

• Abstinence – Avoid STI’s

Problems Male Reproductive System

• Hernia – intestine pushes through abdominal wall- lifting heavy object- lump in groin area & pain

• Testicular cancer – ages 14-40 common self-exam

• Prostate cancer – rectal exam after 40• Sterility – inability to reproduce (Can be

caused by environmental hazards, steroid use, other drug use, some medications, or diseases and STI’s
