What is an organ
organs
that
work
system?
together to perform the
same life function
Examples
Muscular system
Digestive system
Nervous system
Circulatory system
Excretory system
Reproductive system
Skeletal system
Endocrine system
Respiratory system
Immune system
What is an organ?
An organ is a group
of similar tissues that
work together to
perform that same
life function
What is a tissue?
A group of similar
cells that work
together to perform
the same life
function
Tissue that covers and
protects parts of the
body
Examples
tissue that provides for
all body movement
1. Striated muscle
2. Smooth muscle
3. Cardiac muscle
a. Striated/
Skeletal
Muscle
Muscles that are
attached to the
skeleton.
They are voluntary
……you have control
over their activities
b. Smooth
Muscle
Inside the
stomach,
Lungs,
bladder
Smooth muscle is
found in the organs
Smooth muscle is
involuntary….
means that you can
not control the
actions of this type of

3) stomach
4) organelle
Muscle cells in athletes often have more
mitochondria than muscle cells in non-athletes.
Based on this observation, it can be inferred that
the muscle cells in athletes
1. have a smaller demand for
cell proteins than the muscle
cells of non-athletes
2. reproduce less frequently than the
muscle cells of non-athletes
3. have nuclei containing more DNA
than nuclei in the muscle cells of nonathletes
4. have a greater demand for energy than
the muscle cells of non-athletes
