Reproductive System Gisselle De Jesus Per.1
Major functions of the Reproductive system
Bulbourethral gland
Secretes fluid that lubricates end of penis
Scrotum
Encloses, protects, and regulates temperature of testes
Prostate gland
Secretes a fluid that contains citrate, a nutrient for sperm
Penis
Conveys urine and semen to outside of body; insertedinto vagina during sexual intercourse; the glans penis isrichly supplied with sensory nerve endings associatedwith feelings of pleasure during sexual stimulation
Seminal vesicle
Secretes an alkaline fluid containing nutrients and prostaglandins that helps regulate pH of semen
Ductus deferens
Conveys sperm cells to ejaculatory duct
Epididymis
Promotes sperm cell maturation; stores sperm cellsconveys sperm cells to ductus deferens
Interstitial cells
Produce and secrete male sex hormones
Seminiferous tubules
Produce sperm cells
Disorders associated with the reproductive system
Genital warts
Warts on gentials
Gonorrhea
Usually none, painful urination
Genital herpes
Genital sores and fever
Syphilis
rash, damage to heart, liver, nerves, brain
Chlamydia infection
Painful urination and intercourse,
Aids
fever weakness, infections,cancer
Events of the female hormonal cycles
Follicular cells produce and secrete estrogens.
The anterior pituitary releases a surge of LH, which leads to ovulation.
FSH stimulates maturation of a dominant follicle.
Follicular cells become corpus luteum cells, which secrete estrogens and progesterone
The anterior pituitary gland secretes stimulating hormone (FSH) and (LH)
If the secondary oocyte is not fertilized, the corpus luteum degenerates and no longer secretes estrogens and progesterone
As the concentrations of estrogens and progesterone decline, blood vessels in the endometrium constrict
The uterine lining disintegrates and sloughs off, producing a menstrual flow
The anterior pituitary gland is no longer inhibited and again secretes FSH and LH
The menstrual cycle repeats
Anatomy of female reproductive structures
Labia majora
meet to form the mons pubis
Labia minora
flattened, longitudinal folds between the labia majora & forms a hood around the clitoris
Vagina
Wall of three layers, has fibromuscular tube that extends from the uterus to the outside
Clitoris
small projection at the anterior end of vulva between labia minora
Uterus
Hollow muscular organ
Vestibule
space enclosed by the labia minora, into which the vagina and urethra open
Uterine Tube
Lead from the ovary to the uterus
Ovary
solid,ovoid structure
Vestibular glands
Lie on either side of the vaginal opening correspond to bulbourethral glands and provide lubrication
Anatomy of male reproductive structures
Prostate Gland
chestnut-shaped structure surrounding the urethra at the base of the urinary bladder
Bulbourethral Glands
small glands located inferior to prostate gland
Seminal Vesicles
saclike structure attached to the vas deferens near the base of the urinary bladder
Semen
transported throught the urethra to the outside of the body during ejaculation; containg sperm cells
Ductus Deferens
Muscular tube, leading from the epididymis into body cavity
Scrotum
pouch of skin and subcutaneous tissue that houses the testes, suspended from the lower abdomen, posterior to the penis
Epididymis
Tightly coiled tube connected to the testis, leading from the testis to the ductus deferens
Penis
cylindrical organ that conveys both urine and semen to the outside
Testes
consists of 250 loubles separated by connective tissue septa
Methods and Classification of contraceptives
Injectable contraception
Contraceptive implants
IUDs intraterine devices
Sterilization
coitus interruptus
Mechanical barriers
Chemical barriers
Combined hormone contraceptives
Rythum method
Birth control
avoids fertilization and prevents implantaion
Hormones of the Reproductive system
Porgesterone
triggers uterine changes during the menstrual cycle
Estrogens
responsible for female secondary sexual characteristics
Testosterone
stimulates development of male reproductive organs and responsible for male secondary sexual characterisitcs
androgens
produce some changes at puberty such as growth of public and axillary hair
