The Human Body…
How many systems are in the
Human Body?
BODY SYSTEMS
1. Skeletal System  bones
• provides internal support
• protects vital tissues
and organs
• allows for muscle
attachment
• production of blood cells
BODY SYSTEMS
2. Muscular System  muscles
• contract together
(rarely alone)
• move the bones they
are anchored to
• produce body heat
BODY SYSTEMS
3. Nervous System  neurons
• the brain, spinal cord,
and networks of nerves
receive messages from
in and outside body
• nerves transmit instructions
for all body activities,
learning and memory
BODY SYSTEMS
4. Endocrine System  endocrine glands
• produces hormones
(chemical messengers)
• hormones secrete into
blood and are carried to
every cell in body
• hormones regulate the
activity of specific tissues
and organs
BODY SYSTEMS
5. Circulatory System  heart, blood and vessels
• delivers oxygen and nutrients
to all cells
• removes waste from cells via
blood
BODY SYSTEMS
6. Respiratory System  lungs
• Allows for breathing to occur
• exchange of gases between the
inside and outside
of the body
• movement of gas
molecules to and
from the blood
BODY SYSTEMS
7. Integumentary System  skin, hair and nails
•
•
•
•
protects internal body
provides external support
contains sensory receptors
assists in regulating body
temperature
BODY SYSTEMS
8. Lymphatic and Immune Systems
 lymph glands and vessels, spleen,
tonsils, thymus gland etc.
• restores excess interstitial fluid
and proteins to the blood via the
subclavian veins
• absorbs fats and fat-soluble
vitamins from the digestive system
• defends against invading
organisms (eg. bacteria, viruses)
by storing white blood cells in
lymph nodes, spleen etc. (immune
system)
BODY SYSTEMS
9. Digestive System
 long passageway called the
alimentary canal (digestive
tract)
• breaks down food materials
• absorbs food materials
• excretes waste materials
BODY SYSTEMS
10. Urinary System  2 kidneys, 2 ureters, a
bladder and a urethra
• maintains balance of
chemicals in body
• removes waste products
from blood as urine
BODY SYSTEMS
11. Reproductive System
Female:
• organs are situated inside
body
• function to ripen and release
egg at regular intervals
• provide protection and
nourishment for fertilized egg
(embryo) and fetus
BODY SYSTEMS
11. Reproductive System
Male:
• organs situated inside
and outside of body
• function to continuously
produce sex cells (gametes)
called sperm, reducing with
age
TASK:
1. Your group will be given 5 particular
scenarios
2. Work together to try to:
i) Identify the systems involved in the
scenario
ii) Describe the connections between the
body systems
*HINT*
Consider how the body
systems work together!
