1. Reproduction Human anatomy

2.  Introduction A.Adolescence- the period between childhood and adulthood B.Puberty- the time when a person begins to develop certain traits of adults of his or her gender. C.Brain- A.Hypothalamus-The hypothalamus is an area of the brain that produces hormones that control: hunger, sleep, thirst, body temperature, sex drive. B.Pituitary glands- regulates and controls the activities of all other endocrine systems. C.Gonads- a sex organ that produces sperm or eggs : a testicle or an ovary

3. Female development  Secondary sexual characteristics  Pubic hair  Breasts begin to develop  Menstruation begins  Glands begin to develop on the skin and scalp, which produces more oil and can cause blemishes.  Body is taller  Exhaustion due to changes in body.

4. Female Reproduction Anatomy Physiology  Female anatomy- the function of the female reproductive organs is to produce and provide a mature ovum (egg)  1. ovaries-the female sex glands that store the ova and produce female sex hormones.  a. ovulation- the process of releasing a mature ovum into the fallopian tube each month.  Fallopian Tubes- pair of long narrow ducts transports male sperm. Ideal place for fertilization.  2. Uterus- hollow, muscular, pear shaped organ that nourishes and protects a fertilized ovum until birth.  Endometrium- lining of the uterus preventing adhesion.  Menstruation- or period is a monthly series of change where one ovary releases an egg.

5. Female Reproduction  4. Cervix-the opening to the uterus  5. Vagina-muscular elastic passageway that extends from the uterus to the outside of the body  6. Breasts- glandular organs on the chest of a woman; the human mammary gland.

6. Male development  Secondary sexual characteristics  1. body hair increase  2. larynx enlargement and thickening of the vocal folds to lower voice pitch  3. increased muscular growth  4. Testosterone increase  5. body growth  6. Enlarged testes

7. Male development  Anatomy-physiology- the function of these organs are to produce, store, and deliver sperm for the purpose of reproduction.  1. scrotum-an external skin sac.  2. testicles- two glands that secrete testosterone and produce sperm.  3. epidermis- A long, narrow, convoluted tube, part of the spermatic duct system.  4. Vas deferens- tubes that extend from each epididymis to the urethra.  5. Seminal vesicles- as sperm move through the vas deferens, they are combined with a fluid produced.

8. Male development  Prostate glands-the prostate is a walnut-sized gland located between the bladder and the penis. Secretes and protects sperm.  Urethra- is the passageway through which both semen and urine leave the male body.  Penis- tube shaped organ that extends from the trunk of the body just above the testes.  Conception- the process of becoming pregnant involving fertilization or implantation or both  Fraternal twins-The babies can be either the same sex or different sexes, with the odds roughly equal for each.  Identical twins- The babies are identical in looks. Height or weight may be different. Facial distinctions are visible.

9. Fertility awareness  A. Endometriosis- occurs when uterine tissue grows in the ovaries, fallopian tubes, or the lining of the pelvic cavity.  B. Sexually transmitted diseases- spread during sexual contact. Untreated STDs such as gonorrhea and chlamydia.  C. vaginitis- results in discharge, odor, pain, itching, or burning.  D. Ovarian cysts- are fluid filled sacs on the ovary. Small, noncancerous cysts may disappear on their own.
