by area (ex: abdomen, upper limb, lower limb, back)

macroscopic/gross

large body structures that can be seen by the naked eye

microscopic

Chemical level

atoms combine to form molecules

cellular level

cells are made up of molecules

tissue level

consist of similar types of cells

organ level

are made up of different types of tissues

organ level system

consists of different organs that work together

integumentary

organs: hair, skin, fingernails

Functions:

• form the external body covering

• protects deep tissues from injury

skeletal

organs: cartilage, joints, bones

• where the blood cells are formed- because blood cells are made by the bone marrow

• Muscular

Organs- skeletal muscles

Functions:

• allows the manipulation of the environment, locomotion, and facial expression

• maintains posture

• produces heat

TO REMEMBER:

• muscles, tendons, bones

• meaning, muscles are connected to the bones by the tendons

Nervous
