The document discusses two of the main human body systems: 1. The reproductive system, which includes organs like the penis, testicles, ovaries, uterus, and vagina that enable sexual reproduction and production of sperm and eggs. 2. The respiratory system, whose organs like the nose, throat, lungs, and airways allow humans to breathe by inhaling oxygen and exhaling carbon dioxide through a process of gaseous exchange. Both systems are made up of different organs that work together for their specialized functions in the human body.

1. TWO OF THE HUMAN
BODY SYSTEMS

2. Human Body Systems
• The human body is made up of
different systems that work together
to keep it alive.
1. Reproductive System
2. Respiratory System
• The body systems are made up of
organs that function together.

3. HUMAN
REPRODUCTIVE
SYSTEMS

4. • Human reproduce sexually.
• The human body has
special organs (respiratory)
for reproduction.

Penis Composed of Deposits sperm
spongy tissues cells in the vagina
and covered by a
loose flap of skin
called the roreskin

7. Scrotum Small suspended Holds the testicles
sac-like structure
which contains the
testicles (testes).
Testicle/Testes Long, tightly coiled Produces the male
tube which lies sex cells (sperm)
behind each and male sex
testicle. hormone
(testosterone)
Epididymis Sperm duct or Serves as a
tube storage for sperm

8. Vas deferens A group of small Enables the
glands around the developed sperm
urethra from epididymis to
pass through
Prostate gland Found at the Produces prostate

Urethra A tube which Enables sperms to

Reproductive Organs
Female Reproductive Structure Functions
Organs
Ovaries Small, oval- shaped Produce the female cells
organs at either side of and hormones (estrogen
the uterus, just above the and progesterone)
pelvic bone
Uterus (womb) Found at the front of the Nourishes the fertilized
lower abdomen and eggs
behind the urinary
bladder
Cervix Narrow outer end pf the Stretches open wide
uterus enough for the baby to
pass through during
delivery

10. Vagina A canal that leads from Enables sperm to enter
the uterus to the external and menstrual fluid to
opening of the vulva flow out
Vulva Area around the opening Lubricates; produces
of the female urinary and fluids that facilitates the
reproductive systems; passage of sperm
consists of two-folds of
tissue (labia)
Fallopian tubes A pair of tubes stretching Directs the egg from the
from the ovary to the ovary to the uterus
uterus

11. Respiratory Systems

12. Respiratory Systems
• The parts of the body that help people
breath.
• Breathing is one of the involuntary actions
people do.
• Gaseous exchange takes place by
inhaling oxygen and exhaling carbon
dioxide.
