Additional Organ Systems
The three Primary Organ Systems keep each cell alive
but multi-cellular organism are able to do more
than just stay alive
they can move, react, reproduce and more
1. Integumentary System
skin, hair,
finger & toe nails
covers and protects the body
this is very evident in the case
of a burn victim
they risk getting infections
from bacteria and fungus
2. Skeletal System
bones and cartilage
cartilage
bone
a. supports body
and individual parts
eg. cartilage & nose
b. allows movement
c. protects organs
Protected by ribs
lungs
heart
liver
kidneys
stomach
3. Muscular System
a. there are three types of muscles
as mentioned in the ‘tissue’ notes
b. plus tendons
that bind bone to muscle
c. and ligaments
that bind bone to bone
all 3 of these combine to allow the movement of bones
which leads to the movement of the whole organism
4. Nervous System
a. neurons, the long ‘wires’ of the system
b. spinal chord
the main conduit of
the system
all signals must
pass though this
c. the brain
it sorts out the signals
and coordinates a response
these work together to control other organ systems
and coordinate responses and actions
5. Endocrine System
a series of glands
that release hormones
chemicals that circulate in the blood
and affect target cells
eg. insulin and
normal blood sugar
epinephrine and sudden changes in blood sugar
(adrenaline) is the brand name
when some one has an allergic reaction,
an ‘epipen’ releases the hormone that saves them
6. Excretory System
the skin and the kidney
that work to eliminate cellular waste
the skin by sweating out water, minerals and CO2
the kidney by collecting and releasing wastes in urine
What is in urine?
the major portion of
waste is urea
a toxic product of
protein metabolism
7. Reproductive System
male  testes, vas deferens, prostate, etc
all designed to deliver healthy sperm
female  ovaries, fallopian tube, vagina
are responsible for getting egg to sperm
Fallopian tube
the uterus is responsible for nourishing the embryo
the mammary glands are responsible for
nourishing the baby after birth
8. Lymphatic System
lymph vessels,
lymph nodes,
white blood cells
spleen and
thymus gland
all work together to protect the body
from viruses & bacteria
