Transcript of The Reproductive System

The Reproductive System By: Bailey Elsberg, Vanessa Hinojos, and J.T. Rarden Female Reproductive System Male Reproductive System Important vocab Important vocab Structure Function Purpose: create sperm and transfer it to the females body during sexual intercourse

When maturity level is reached

Pituitary gland releases the male sex hormone

Stimulated testis start producing testosterone

Initiates physical changes Seminal vesicle: A pair of pouchlike glands that secrete seminal fluid, nourish and promote the movement of spermatozoa through the urethra

Vas deferens: The main duct through which semen is carried from the epididymis to the ejaculatory duct

Ejaculatory duct: A canal through which semen is ejaculated

Prostate gland: Secretes proteins and hormones that that make a fluid medium protects the sperm

Cowper's gland: Discharges a secretion into the semen which provides lubrication

Urethra: A narrow fibromuscular tube that conducts urine and semen from the bladder and ejaculatory ducts, respectively, to the exterior of the body

Epididymis: A longcordlike structure along the border of the testis; its coiled duct provides for storage, transit, and maturation of spermatozoa and is continuous with the ductus deferens

Testis: The male gonad; paired egg-shaped glands located in the scrotum

Scrotum: The pouch containing the testes and their accessory organs Fallopian tube: A pair of tubes with fingerlike projections that draw the ovum in
Ovaries: Female sex glands
Uterus: A small muscular, pear-shaped organ, about the size of a fist
Cervix: The neck of the uterus
Vagina: The muscular, elastic passageway that joins the cervix to the outside of the body
Urethra: Separate tube that urine exits the body
Labia minora: "small lips" lie inside the labia majora, and surround the opening of the vagina and urethra
Labia majora: "large lips" enclose and protect the other external organs. during puberty hair growth occurs here
Clitoris: A small, sensory organ
Bartholin's glands: Glands located by the vaginal opening on each side a fluid (mucus) secrection
Endomitrium: The lining of the uterus External organs
Labia majora
Labia minora
Bartholin's glands

Internal organs
Uterus (womb)
Fallopian tubes
Endomitrium How the system works Care
Shower daily
Avoid tight clothing
Wear protectors during strenuous activities
Monthly self-examinations
Enlarged prostate gland
Cancer of the prostate gland
Cancer of the testes The scrotum holds the testes in place and controls their temperature
The testis produce the sperm
The epididymis holds and stores the sperm
Sperm mature here
The vas deferens transports the sperm up and through
The seminal vesicle
Secrete a fluid that contains nutrients and nourishes the sperm
Mixes to make mobile
The prostate gland
Secretes proteins and hormones to the sperm
Cowper's gland
Discharges secretion into the semen providing lubrication to the sperm
Neutralizes the acid content before ejaculation
The urethra disposes both semen and urine outside the body
The Penis enters the vagina and transports the semen Care & Problems Structure Reproductive organs inside and outside the pelvis
External organs
Endocrine system
The Testes
Produce and store millions of sperm
The hormone Testosterone
Shaft and Glans
Internal organs
The Duct system
Vas Deferens (ductus)
The Accessory Glands
Seminal vesicles
Prostate gland
Cowper's gland(bulbourethral) Care & Problems How the system works Function The main function is to reproduce

To nourish and protect each fertilized ovum from beginning of pregnancy till birth
Ovaries produce the hormones
Progesterone The ovaries hold and produce the female egg cells ova or oocytes
The part of the brain hypothalamus releases increasing amounts of gondaotrophin-releasing hormone (GnRh)
This stimulates the pituitary gland to produce
Luetinising hormone (LH)
Follicle-stimulating hormone (FSH)
The ovum (mature ova) breaks out one of the ovaries
Thickening of the uterine wall
The fimbriae (fingerlike strands) of the fallopian tube catches ovum
Drawing the ovum in the fallopian tube
If sperm enters the fallopian tube fertilization may occur
If fertilized, the ovum now becomes a Zygote
Once formed zygote leaves fallopian tube, and travels into the uterus
Zygote attaches the uterine wall and grows
If fertilization does not occur
The uterine wall breaks down into blood, tissue, and fluids
The support for pregnancy is no longer needed
Menstrual period
The process of shedding the lining of the uterus
Female sex hormones maintain this cycle over and over Care
Shower daily
Important during menstrual period
Monthly Self-examinations
Related to Menstruation
Menstrual Cramps
Premenstrual Syndrome(PMS)
Toxic Shock Syndrome (TSS)
Related to Infertility
Blocked Fallopian tube
Pelvic Inflammatory Disease (PID)
Ovarian Cyst
Cervical Cancer
