gives the body shape and protects the organs,
consists of 206 bones
move muscles and some organs, consist of muscles
attached to bones or tissues of some organs
carries oxygen into the lungs for transfer to the
blood and removes carbon dioxide from the blood
for release from the body
moves oxygen and nutrients to the cells, uses blood
and blood vessels
moves waste materials out of the body
carries messages throughout the body and controls
your senses, includes brain, spinal chord, and
nerves
Turns food into nutrients that are suitable for use by
the body.
protects the body from injury and infection and
removes waste, includes skin, hair, and nails
protects and fights against disease and illness,
helps heal injuries, consists of cells that attack and
kills disease organisms in tissues
produces chemicals that regulate and control body
functions.
produces offspring
What are the organ systems in your body?
Main Idea
Your body’s organ systems enable it to carry out life processes.
Supporting Details
A. Human body is a complex machine that does multiple jobs at the same time.
B. Composition
a. A cell is the smallest unit of life in the human body.
b. Tissues are a group of cells that work together for a common function.
c. Different tissues are organized into different organs
d. The organs work together as part of an organ system to perform
specific functions in the body.

How are body materials transported?
Main Idea
Your organ transport system move materials throughout the body.
Supporting Details
A. Our bodies need a transport system to move need materials to the proper
places and remove any unneeded materials.
B. Moving needed materials
a. Digestive system – breaks down food pulling out and absorbing
needed materials and passing on unneeded material
b. Respiratory system – brings in oxygen that is absorbed into the blood
c. Circulatory system – transport absorbed oxygen and nutrients to the
different cells
C. Moving unneeded materials / waste
a. Circulatory system – moves carbon dioxide and water from the cells to
the excretory and respiratory systems for disposal
b. Excretory system – Filters blood and removes waste in it and
transports the waste outside of the body
c. Respiratory system – removes carbon dioxide from blood and
transports it outside of the body
