Reproductive System - Dayanara Torres
Major Functions Of Reproductive System
The reproductive system is the only system a person doesn't need to survive & its purpose is is it develops & maintains organs for production of an offspring & it has organs/systems to do that. Oogenesis: process of oocyte production that starts at puberty, some oocytes are stimulated to continue meiosis. Epididymis: Tightly coiled tube connected to the testis to the ducts deferens & is the site of sperm maturation. Gonads:testes & ovaries produce gametes which are sex cells & hormones
Anatomy Of Male Reproductive System
Primary Sex Organs (gonads) of a male: testes produce sperm & hormone
Testes are ovoid structures suspended by spermatic cord outside the trunk in a sac the scrotum. Male internal Accessory Reproductive Organs nurture & transport sperm.
Accessory (secondary) Sex Organs of a male: internal & external reproductive organs
Scrotum: a pouch of skin & subcutaneous tissue that houses testis
Penis: cylindrical organ that conveys both urine & semen to the outside
Emission: movement of sperm cells & accessory gland secretions into urethra
Ejaculation: forcing of semen through urethra to outside of the body
Steroli cells:support, nourish, & regulate the spermatogenic cells
Androgen's of a male sex hormones: testosterone is the most important
Anatomy Of Female Reproductive System
Produce & maintain sex cells(egg cells/oocytes), transport cells to fertilization site, provide environment for developing fetus, deliver, feed, & nurture offspring, & produce female sex hormones.
Medulla: made of connective tissue, blood vessels, & lymphatic vessels & nerves
Cortex: contains ovarian follicles & is covered by cuboidal epithelium
Female internal accessory organs consist of uterine tubes, uterus, & vagina
Uterine Tubes: lead from ovary & they expand to form an infundibulum with finger like fimbriae on its margins
Uterus: receives embryo from uterine tubes & maintain development of the embryo & fetus
Labia Majora: enclose & protect other external reproductive organs
Labia Minora: flattened. longitudinal fold between labia Majora, form around hood of clitoris
Clitoris: small projection to anterior end of vulva between labia minora, corresponds to penis & has similar structure, & contains columns of erectile tissue
Vestibule: space enclosed by labia minora into which the vagina & urethra open
Ovulation: process of releasing secondary oocyte & polar body from the mature antral follicle & surfaces the ovary
Hormones Of Reproductive System
Estrogens: responsible for female secondary sexual characteristics
Androgen's: produce some changes at puberty
Gondadotropin-releasing hormone (GnRH): secreted by the hypothalamus & triggers the production of gandotropins from anterior pituitary glands
Luteinizing Hormone (LH): promotes development of interstitial cells of testis which secrete male hormone
Follicle-stimulating hormone (FSH): stimulates sertoli cells of semini ferours tubules to respond to testosterone
Events Of Female Hormonal Cycle
Hormones secreted by the hypothalamus, the anterior pituitary & ovaries control females reproduction maturation of sex cells & development of secondary sexual characteristics.The mentsural cycle plays a roll which is monthly changes in the uterine lining
Menarche: first female reproductive cycle: occurs when reproductive organs have matured & behind responding to females hormones
Disorders Associated With Reproductive System
PID: infection of woman's reproductive organs
Trichomoniasis: STD that's caused by infection with a protozoan parasite
AIDS/HIV: Virus that attacks the body's immune system & if HIV isn't treated it leads to AIDS
HPV/Genital Warts: An STI with many different types
Syphilis: An STI that can cause health problems if not treated
Genital Herpes: An STD caused by herpes simplex virus 1
Chlamydia: An STD in men and woman that can cause permanent damage to a woman's reproductive system
Gonorrhea: An STD that can infect men and woman
Hepatitis: Mild illness with few or no symptoms or serious illness that can lead to chronic or lifelong infection
Methods & Classification Of Contraceptives
Coitus Interrupts: withdrawal of penis from vagina before ejaculation
Rythm Method: abstinence from sexual intercourse around time of ovulation
Mechanical Barriers: prevent sperm from entering vagina during intercourse (condoms)
Chemical Barriers: contain spermicides & is more effective when using a condom
Combined Hormone Contraceptives: contain estrogen & progestins to prevent pregnancy
Injectable Contraceptive: injecting of progesterone derivate prevents follicle maturation & ovulation (works for 3 weeks)
Contraceptive Implants: implantation of a rod containing progesterone under skin in the arm
Intrauterine Devices (IUDS): objects implanted in uterus either toxic to sperm & egg cells or prevent implantation of embryo
Sterilization: surgical methods of permanently preventing pregnancy
