Living Organisms carry out life
processes in order to survive.
The human body is complex.
Cells
Tissues
Organs
Systems
Living Organisms carry out life
processes in order to survive
Cell = basic unit of life
Tissue = group of similar cells that work together
to perform a function
Organ = group of different tissues that work
together to carry out a function in the
body
System = group of organs that work together to
perform a function to meet material
and energy requirements
Living Organisms carry out life processes
in order to survive
The body’s systems interact with one
another.
HOMEOSTASIS
The ability of your body to
maintain internal conditions.
Living Organisms carry out life
processes in order to survive
HOMEOSTASIS
Keeps the following
balanced….
• Body temperature
• Amount of blood sugar
• Posture
(There are other examples.)
Living Organisms carry out life

The body’s systems interact
with one another.
Body Systems
Skeletal
Muscular
Cardiovascular
Respiratory
Digestive
Nervous
Endocrine
Urinary
Integumentary
Reproductive
The body’s systems interact with
one another.
Skeletal System = interacts with muscles
& cardiovascular system
MOVEMENT
PRODUCES
BLOOD
Axial Skeleton = skull, rib cage, backbone
Appendicular Skeleton = shoulders, hips, arms, legs
Joints = free moving, immovable, slightly movable
The body’s systems interact with
one another.
Muscular System = interacts with skeletal
and nervous systems
MOVEMENT
POSTURE
MOVEMENT
BODY TEMPERATURE
The body’s systems interact with
one another.
Muscular System = interacts with skeletal
and nervous systems
Skeletal Muscle = voluntary
triceps
rectus abdominus
Smooth Muscle = involuntary
digestive system
arteries, veins
Cardiac Muscle = involuntary
heart
The body’s systems interact
with one another.
Muscular System = interacts with skeletal
and nervous systems
Skeletal muscles & tendons
allow bones to move.
•Tendons = strong tissues that
attached muscles to bones
•As fibers in a muscle contract, they
shorten and pull the tendon.
•The tendon then pulls the bone.
Muscular System
= interacts with skeletal
and nervous systems
Muscles work with nerves to
produce movement.
• Communication between the nerve
cells and muscle cells produce muscle
contractions.
• The communication involves the
diffusion of elements in and out of
the muscle and nerve cells.
