HUMAN REPRODUCTIVE SYSTEM & LIFE CYCLE
Male Reproductive System
Parts & Functions
external genitals
penis
- it has spongy tissue and contains urethra that carries urine and semen.
It is used for urination and sexual intercourse.
scrotum
- has the shape of a sac & divides into two compartments.
It holds the testes (testicles) in place.
testes
- these are pair of
egg-shaped glands that found in the scrotum
Responsible for making sperm and
involved also in producing testosterone.
internal parts
prostate gland
- a walnut-sized gland that found in the middle of the pelvis.
Produce a fluid that nourishes
and transports sperm
vas deferens
- long muscular tube runs from the epididymis into the pelvic cavity.
It carries sperm from
epididymis up to urethra
urethra
- a tube that extends from the bladder to the external opening at the end of the penis.
It lets the urine leave
your bladder and body.
Female Reproductive System
Parts & Functions
Ovaries
- these 2 oval-shaped are attached to each side of the uterus by a ligament
Produces eggs for
fertilization and make
estrogen and progesterone
hormones.
Fallopian Tube
- these are 2 thin tubes
that connect the ovaries to the uterus
Allows the egg to
travel to the uterus.
Uterus
- also called the womb, an
inverted pear-shaped muscular organ
To nourish and house
a fertilized egg
until the fetus, or offspring,
is ready to be delivered.
Cervix
- it is a muscular, tunnel-like organ.
Allows the fluids to pass
between your uterus
and vagina.
Vagina
- 3 1/2 inch long muscular tube that expands during sexual arousal.
For copulation, receiving
the seminal fluid from
the male penis.
Menstrual Cycle
- the sequence of events as it prepares for the possibility of pregnancy each month.
Menstruation
- the monthly shedding of the lining of the uterus. It typically begins at 12 years old, with some individuals starting as early as 8 or 16 years, and ends around 51 years old, with ovulation stopped.
Menstrual blood
- partly blood and tissue from inside of the uterus.
Phases of Menstrual Cycle
Menses phase
- The period from day one to day five is when the uterus's lining sheds through the vagina, if pregnancy hasn't occurred.
Follicular phase
- During days
six to 14, estrogen and FSH
hormones stimulate uterine growth
and follicle- stimulating hormone (FSH) development, leading to the formation
of a mature egg.
Ovulation
- Ovulation occurs at day
14 in a 28-day menstrual cycle, triggered
by a sudden increase in luteinizing
hormone (LH), which causes the ovary
to release its egg.
Luteal phase
- The 15-28 day phase involves the egg leaving the ovary, progesterone levels rising, and implantation. Pregnancy occurs if the egg fertilizes, while if not, estrogen and progesterone levels drop and uterine lining sheds.
