Reproduction Human anatomy
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
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.
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.
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.
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
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.
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.
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.
