Body Systems
Integumentary Systems


Organs Included:
Skin, hair, nails,
sweat glands,
sebaceous (oil)
glands
Function: Covers
and protects the
body, controls body
temperature,
prevents fluids from
leaving the body
Skeletal System

•
Includes: all bones
Joints= The place where 2
bones meet, allowing the
skeleton to move.
Ligaments= Bands of
connective tissue that
connect the 2 bones that
form joints
Function: Supports the
body, helps with movement
and protects internal
organs.
Muscular System




Includes: skeletal muscle=
voluntary (can be controlled)
and makes up the muscles that
moves the skeleton.
Cardiac muscle= involuntary
(cannot be controlled) and
makes up the heart muscle.
Smooth muscle= involuntary,
and is found in the walls of the
body (ex: stomach, intestines,
blood vessels)
Function: Moves food
through the digestive tract,
allows movement, causes
heart to contract.
Circulatory System



Includes: Heart, arteries,
veins
Function: Carries oxygen
(oxygenated blood) from the
lungs to all the body cells
and removes waste.
Note: Arteries are red and
carry oxygenated blood
away from the heart. Veins
are blue, and carry
unoxygenated blood to the
heart.
Respiratory System


Includes: Nose,
mouth, pharynx, larynx
and lungs.
Function: Takes
oxygen from the
air/lungs and delivers it
to all body cells.
Removes carbon
dioxide from the body.
Digestive System



Includes: Mouth,
esophagus, stomach,
intestine, liver and
pancreas.
Function: Breaks down
food to a form the body can
use.
Note: There are 2 types of
digestion. Mechanical
digestion (chewing), and
chemical digestion
(stomach acid breaking
down food).
Immune System


Includes: Lymph nodes,
tonsils, spleen, lymphatic
vessels and bone
marrow.
Function: Protects the
body from disease.
Endocrine System


Includes:
Hypothalamus, pituitary
gland, thyroid, adrenal
glands and gonads.
Function: Makes
hormones, controls
growth, metabolism and
reproduction.
Reproductive System


Includes: Female=
ovaries, fallopian tubes,
uterus and vagina.
Male= penis, scrotum,
testes, vas deferens,
prostate and urethra.
Function: Produces
offspring
Urinary/Excretory System


Includes: kidneys,
ureters, bladder and
urethra.
Function: Removes
nitrogenous waste from
the body in the form of
urine.
Nervous System


Includes: Brain and
spinal cord.
Function: Carries
information between all
parts of the body and
the brain.
Practice Questions!

A.
B.
C.
D.
Which three systems are involved in the
excretion of wastes in humans?
Urinary, skeletal, reproductive
Circulatory, integumentary, muscular
Digestive, respiratory, urinary
Nervous, endocrine, immune
Answer!



The answer is C!!!
The digestive system releases waste from
the anus, the respiratory releases carbon
dioxide and the urinary system expels
nitrogenous waste as urine.
Remember the urinary system is also known
as the excretory system.
Question

A.
B.
C.
D.
What is the function of nerve tissue in the
skin?
It helps skin keep its elasticity
It helps detect stimuli from the environment
It maintains the body’s temperature
It produces sweat in response to an
increase in body temperature.
Answer


The answer is B!
Neurons the main part of the nervous system,
are cells that receive messages among the
many parts of the body, brain and spinal cord.
Question

A.
B.
C.
D.
Which systems are involved in breathing?
Respiratory, circulatory, nervous
Skeletal, muscular, respiratory
Excretory, muscular, digestive
Nervous, skeletal, integumentary
Answer


The answer is A!
Remember the nervous system controls
everything that body does, and the alveoli
(found in our lungs) are air sacs surrounded
by tiny blood vessels-parts of the circulatory
system. We have to get oxygen into our
blood!
Question

A.
B.
C.
D.
What role does the nervous system play in
digestion?
It causes motor neurons to carry impulses
away from the brain and spinal cord.
It stimulates the secretion of saliva, stomach
acids, and hormones.
It causes the pacemaker to speed up or
slow down.
It regulates breathing.
Answer


The Answer is B!
The nervous system causes the mouth,
stomach, and glands of the endocrine system
to secrete saliva and stomach juices in order
to breakdown food.
