The Reproductive System Yaritza Perez P.5
Major Functions of the Reproductive System
Male
Produce & disseminate a large quantity of make gamete
Female
in production of female gamete and preparation for support of developing embryo during pregnancy
Anatomy of Male reproductive
Testes (each lobule contains one to four seminiferous tubules
Spermatogenesis ( production of sperm cells)
Epididymis (to mature & store sperm cells)
Vas Deferns (ductus deferns) (carries sperm from the epididymis to the ejaculatory duct
Urethra( carries both sperm & urine)
Semen( provide transport medium for sperm)
Seminal Vesicle (contains fructose vitamin C & other substance that nourish & activate the sperm
Prostate Gland (secretes a milky fluid that helps activate sperm
Cowpowers Gland (secrete analkaline mucus in response to sexual stimulation & lubricates penis for penetration just before ejaculation)
Scrotum (divided sac of skin outside the abdomen that holds the teste
Penis (Delivers semen into female reproductive tract regions of penis)
Anatomy of Female Reproductive
ovaries- primary female sex organs
Ductus system- delivery of female gamete
secondary/accessory
uterine (fallopian) tube
uterus
vagina
broad ligament- attached to pelvis| round ligament- anchor interiorly| utersoral ligament- anchored posteriory
Regions of regions
Body- main portion
Fundus- area where uterine tube enters
Cervix- narrow outlet that protudes into the ragging or opening into the uterus
walls of the uterus
endometrium- inner layer; allows for implantation of fertilized eggs
myometrium-middle layer of smooth muscle
perimetrium- outer layer visceral peritoneum; covering of abdominal organ
Vagina
hymen- membrane that partially closes the vaginal opening
external genitalia
mon pubis- fatty pad over the pubic symphysis
Labia- skin folds around the vaginal opening
Labia majora- outer fold
labia minora- inner fold
vestibule
ditoris- can become engorged with the blood during sexual stimulation
mammary gland- produce milk
Production of Gamete
when egg & sperm fuse during fertilization = zygote, it matures in the ovary and moves to fallopian tube
Hormones
GnRH- released by hypothalamus
FSH- stimulates the development & maturation of primary follicle into secondary follicle
Luteinizing Hormone- spike of hormone will trigger ovulation of the most mature follicle
Inhibin-decreases release of FSH by anterior pipuitary gland
Estrogen- primary female hormone released by follicle
progesterone- triggers suppression of the hypothalamus from releasing GnRH
reproductive cycle- ovarian cycles ( occurs in the ovaries leading to the maturation & ovulation)- uterine cycle ( menstruation)
disorders
menopause- ovaries no longer respond to hormones
prostate cancer
breast cancer
