Reproductive system Flashcards
Play an important roles in the development of the structural and
functional differences between males and females
Reproductive System
Influence human behavior
Reproductive System
Produce offspring
Reproductive System
Maintenance of a constant or near constant composition of the fluid that
bathes the body cells essential for health.
Homeostasis
State of equilibrium and balance.
Homeostasis
Ovaries, vagina, uterus, mammary
glands & associated structures
Female Reproductive System
Produce oocytes and is the site of
fertilization & fetal development
Female Reproductive System
Produces milk for the newborn
Female Reproductive System
Produce hormones that influence
sexual function & behaviors.
Female Reproductive System
Testes, accessory structures, ducts &
penis
Male Reproductive System
Produce & transfers sperm cells to
the female & produces hormones that
influence sexual functions &
behaviors.
Male Reproductive System
a. Production of Sperm cells
b. Sustaining and transfer of
the sperm cells to the female
c. Production of male sex
hormones.
Male Reproductive System
a. Production of female sex cells
b. Reception of sperm cells from the
males
c. Nurturing the development of and
providing nourishment for the new
individual
d. Production of female sex hormones.
Female Reproductive System
produce sex cells
or gametes.
testes
A saclike structure containing the
testes
Scrotum
The dartos and cremaster muscles help
to regulate testes temperature
Scrotum
A coiled tube system, located on the
testis, that is the site of sperm
maturation.
Ducts: Epididymis
Final changes called capacitation of
sperm cells, occur after ejaculation.
Ducts: Epididymis
The seminiferous tubules lead to the
rete testis.
Ducts: Epididymis
Passes from the epididymis into the
abdominal cavity
Ductus deferens or Vas deferens
formed by the
joining of the ductus deferens and the
duct from the seminal vesicle. Joins the
prostatic urethra in the prostate gland
ejaculatory duct
extends from the urinary
bladder through the penis to the
outside of the body.
urethra
begins in the
seminiferous tubules at the time
of puberty
Spermatogenesis
Sperm cells are produced in
seminiferous tubules
nourish the sperm
cells and produce small amounts
of hormone
Sertoli cells
divide to form
primary spermatocyte
Spermatogonia
divide by
meiosis to first produce
secondary spermatocytes and
then spermatids
Primary spermatocytes
Male organ of copulation and functions in the transfer of
sperm cells from the male to female.
Penis
Consists of erectile tissue; engorgement of this erectile tissue
with blood causes the penis to enlarge and become firm, a
process called erection.
Penis
forms
the ventral portion and the
glans penis, and encloses the
spongy urethra.
Corpus spongiosum
covers the glans
penis.
Prepuce
Glands consisting of many saclike
structures located next to the ampulla
of the ductus deferens
Glands: Seminal Vesicles
empty into the
ejaculatory duct.
Glands: Seminal Vesicles
Consists of glandular and muscular
tissue and empties the urethra
Prostate Gland
About the size and shape of a walnut.
Prostate Gland
Also called the cowper`s glands are a
pair of small mucus-secreting glands
located nead the base of the penis
Bulbourethral Gland
empty the
urethra.
Bulbourethral Gland
mixture of sperm cells and
secretions from the male reproductive
glands.
Semen
contain sperm cells
Testicular secretions
contains nutrients and
proteolytic enzymes, and it neutralizes
the pH of the vagina.
Prostate fluid
movement of sperm cells mucus, prostatic secretions, and seminal
vesicle secretion into the prostatic, membranous and spongy urethra
Emission
first major component of the male sexual act
Erection
forceful expulsion of the secretions that have accumulated in the
urethra to the exterior.
Ejaculation
small organs suspended in the pelvic
cavity by ligaments
Ovaries
layer of visceral peritoneum covers the
surface of the ovary
Ovaries
Release of an oocyte from an ovary. The first
meiotic division is completed and secondary
oocyte is released
Ovulation
usually occurs in
the ampulla of the uterine tube,
which is near the ovary.
Fertilization
Extend from the area of the ovaries to the uterus
Uterine tubes
Part of the uterus superior to the entrance of the uterine tube called the fundus
Uterus
Is a pear-shaped organ. The uterine cavity and the cervical canal are the
spaces formed by the uterus.
Uterus
female organ of
copulation and function to
receive the penis during
intercourse
Vagina
Main part of the uterus is
called the Body, and the
narrower part, the Cervix is
directed inferiorly.
Uterus
Also allows menstrual flow
and childbirth
Vagina
Extends from the uterus to
the outside of the body.
Vagina
Consist of a layer of smooth
muscle and an inner lining
of moist stratified squamous
epithelium
Vagina
produced
by the wall of the vagina
Lubricating fluid
covers the
vestibular opening of the
vagina
Hymen
Also called Vulva, or Pudendum,
consists of the vestibule and its
surrounding structures
External Genitalia
the space into which the
vagina and urethra open.
Vestibule
a small erectile structure, is
composed of erectile tissue and contains many
sensory receptors important in detecting sexual
stimuli
CLITORIS
are folds that cover the
vestibule and form the prepuce
LABIA MINORA
cover the labia minora,
and the pudendal cleft is a space between the
labia majora
LABIA MAJORA
an elevated area
superior to the labia majora
MONS PUBIS
Are organs of milk production and are
located in the breasts
Mammary Glands
Are modified sweat glands that
consist of glandular lobes and
adipose tissue
Mammary Glands
The nipple is
surrounded by
areola
begins with the first menstrual bleeding
PUBERTY
refers to the series of changes that occur in sexually mature,
nonpregnant females and that culminate in menses
MENSTRUAL CYCLE
is a period of mild hemorrhage during which part of the
endometrium is sloughed and expelled from the uterus
MENSES
is the cessation of menstrual cycle
MENOPAUSE
