The Reproductive System
Transcript of The Reproductive System
Male Reproductive System
Human Immunodeficiency Virus
the male gonad responsible for producing spermatozoa and hormones like testosterone
a protective pouch that secures the testes
Keeps the testes at the temperature 95-96.8F
Gonads- female gonads, or ovaries, produce eggs, control hormones and functions of the system.
Follicles- eggs mature inside of the follicle during the menstrual cycle, and then exits during ovulation.
Ovulation- the monthly development of an egg
Fimbriae- the passage between the ovary and the fallopian tube. The cillia sweep the oocyte through this passage.
Fertilization- During sex, semen is releaesed into the vagina, causing the sperm to fertilize the egg in the female.
Sperm are the male reproductive cells that comes from the Latin phrase, sperma, meaning "seed"
Sperm cells cannot reproduce and have a limited survival rate, it sole purpose to fertilize the female sex cell, ova
Semen is made alkaline which helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm
Semen is an organic fluid that may contain sperm cells
It is produced by the gonads and is used to inseminate the ova
It is composed of three main parts: the head, that receives a diluted concentration of sperm, the body, and the tail, which absorbs fluid to make the sperm more concentrated
It's a very narrow, tightly-coiled tube connecting the efferent ducts from the rear of each testicle to its vas deferens that is found in male amniotes
In adult men it can be six to seven meters in length
These tubes transport sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation
The ducts connect the left and right epididymis to the ejaculatory ducts to move sperm through
Funds- the top portion of the uterus, opposite the cervix.
Cervix- the lower part of the uterus which opens into the vagina
Endometrium- acts as a lining for the uterus; maintains patency
Menstruation- monthly shedding of the uterine lining
The organ in which the fetus develops; the womb
A canal the joins the cervix to the outside of the body; birth canal.
The Mons Pubis is a fatty covering that protects the female genitals during sexual intercourse.
The Labia Majora is a large, fleshy piece of skin that protects the internal reproductive system.
The labia Minora is a small piece of skin just inside the Labia Majora.
The Vestibule is the area in between the Labia Minora and the Vaginal opening.
The Clitoris is the organ in the Female that is stimulated in order to have an orgasm.
The Perineum is the region of the
body in between the thighs.
The female Perineum includes most
of the reproductive system.
The Bartholin's Glands
An Areola is any small, circular area on the body colored different from the surrounding skin. The Areola on the Mammary glands are used to excrete milk from the body.
Lactation is the secretion of milk from the Mammary glands.
A Mammogram is an x-ray of the breast. Mammograms are used to check for Breast cancer among other things.
The Bartholin's glands are two glands located on either side of the vagina. During sexual intercourse, these glands secrete fluid that protect the vaginal tissue.
Paired structures in males, each duct is formed by the union of the vas deferens and the duct of the seminal vesicle
They pass through the prostate, and open into the urethra then during ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the tip of the penis
A pair of simple tubular glands posteroinferior to the urinary bladder
Secretes a significant proportion of the fluid that ultimately becomes semen
A exocrine gland of the male reproductive system
Secretes a slightly alkaline fluid, milky white in appearance, that usually constitutes 50-75% of semen along with sperm cells and seminal vesicle fluid
HIV, if untreated, will eventually cause AIDS.
Symptoms of HIV include fever, swollen glands, sore throat, and rash.
AKA: bulbourethral gland; It's one of two small structures about the size of peas, located below the prostate gland
It's composed of many tubes with linings that secrete a fluid released during sexual stimulation to provide some lubrication to the end of the penis in preparation for sexual intercourse although the female reproductive organs provide most of the lubricating
The urethra is about 8 inches long and forms the penis, and it ends at the opening of the penis
It provides an exit for urine as well as semen during ejaculation
The male genital organ of higher vertebrates, carrying the duct for the transfer of sperm during copulation
In humans, it consists largely of erectile tissue that fills with blood during an erection and it serves also for the elimination of urine
The penis is the male equivalent to the clitoris.
An erection is the stiffening and rising of the penis, which occurs during sexual arousal, though it can also happen in non-sexual situations
A double-layered fold of smooth muscle tissue, blood vessels, neurons, skin, and mucous membrane
It covers the glans penis and protects the urinary meatus when the penis is not erect
From Latin circumcidere, meaning "to cut around"
The surgical removal of the foreskin from the human penis
Usually performed shortly after birth
HIV is a virus that attacks the bodies immune system by taking over its white blood cells.
