Human
Body
Systems
7.12 B Identify the main functions of the systems
of the human organism, including the circulatory,
respiratory, skeletal, muscular, digestive,
excretory, reproductive, integumentary, nervous,
and endocrine systems.
Structure: What are
the parts?
Joints and bones
Function:
What is its
job? body
and its
muscles,
contains
materials to
make new
blood cells.
Skeletal System
Structure: What are
the parts?
3 types of muscle: skeletal,
smooth, and cardiac;
ligaments and tendons
Function: What
is its job? Allows
the body to move
when attached to
bone, allows
movement in
internal organs
such as the heart
and intestines,
provides strength,
balance and
warmth.
Muscular System
Structure: What are the
parts?
Mouth, esophagus,
stomach, small and large
intestines, anus
Function: What
is its job?
Converts food into
simpler substances
for the body to
absorb as
nutrients,
breakdown of food
also provides
energy for all body
functions.
Digestive System
Structure: What are the
parts?
Includes heart, arteries
(distribute to body) and
veins (carry deoxygenated
blood to heart)
Function:
What is its job?
Circulates blood
through the body,
supplies cells
with oxygen and
nutrients,
removes waste
products.
Circulatory Systems
Structure: What are the
parts?
Airways such as trachea,
lungs, and alveoli
Function:
What is its
job?
Supplies blood
with oxygen in
the lungs, and
removes
carbon dioxide.
Respiratory System
Structure: What are the
parts?
Kidneys, bladder
Function:
What is its
job?
Filters water
and fluids from
the blood while
also collecting
urine waste.
Excretory
Structure: What are the
parts?
Skin, hair, nails, and sweat
glands
Function: What
is its job?
Continuously
receives
communication
with the external
environment
(temp, humidity)
and protects body
deeper tissues,
excretes waste.
Helps rid body of
heat, synthesizes
Vitamin D.
Integumentary System
Structure: What are the
parts?
Brain, spinal cord, and
nerves.
Function: What
is its job?
Sends immediate
and specific info as
electrical impulses,
control center
coordinating all
actions and
reactions work
together and are
the bodies 2
systems for control
and
communication.
Nervous System
Structure: What are
the parts?
Glands, hormones
Function:
What is its job?
Sends signals in
form of
hormones to the
body but more
slowly than
nervous system,
controls growth,
reproduction,
and metabolism.
Endocrine System
Structure: What are the
parts?
Lymph nodes, tonsils,
spleen
Function:
What is its job?
Responds to
pathogens and
provides defense
to the body’s
systems from
disease caused by
viruses and
bacteria.
Immune System
Structure: What are the
parts?
Females: Uterus, ovaries
Males: Penis, testicles
Function:
What is its job?
Allows humans to
continue as a
species by
fertilizing a
female ovum with
a male sperm
through sexual
reproduction.
Reproductive System
