Organ system level
Association of organs that together performs an overall functions

Movements of the skeleton
Muscular
Movement of blood and lymph
Circulatory
Defense of the body against invading pathogens
Immune
Regulation of blood volume and composition

Integumentary system
Provides muscle attachment for movement
Skeletal system
Types of skeleton
Hydrostatic, Exoskeleton, and Endoskeleton
Fluid-filled chamber that muscles act on, redistributing the fluid
Hydrostatic skeleton
Hard external parts that muscles attach to
Exoskeleton
Hard internal parts that muscles attach to
Endoskeleton
Produces heat
Muscular system
Is the uptake of oxygen and the simultaneous release of carbon dioxide
Respiration
Terrestrial vertebrates that are able to respire through moist skin
Amphibians
Terrestrial vertebrates that their lungs contain many more small chambers, greatly increasing the surface area
Reptiles
Small chamber in interior of lung
Alveoli
Short passageways connecting clusters of alveoli
Bronchioles
The thoracic cavity is bounded on the bottom by a thick layer of muscle
Diaphragm
Transports materials in the body via blood pumped by heart
