Chemical signals
When there is a stimulus, the nervous system uses
Electricity and chemicals
Transports oxygen, nutrients, wastes; helps regulate body temperature; collects fluid lost from blood vessels and returns it to circulatory system
Circulatory
Breaks down and absorbs nutrients, salts, and water; eliminates some wastes
Digestive
Influences, growth, development, metabolism; helps maintain homeostasis
Endocrine
Eliminates waste products; helps maintain homeostasis
Excretory
Protects against disease; stores and generates white blood cells
Immune
Act as a barrier against infection, injury, UV radiation; helps regulate body temperature
Integumentary
Produces voluntary and involuntary movements; helps to circulate blood and move food through digestive system
Muscular
Regulates body’s response to changes in internal and external environment; processes information
Nervous
Produces reproductive cells; in females, provides environment for embryo
Reproductive
Brings in O2 for cells; expels CO2 and water vapor
Respiratory
Supports and protects vital organs; allows movement; stores minerals, serve as the site for red blood cell production

Umbrella species
His contribution was a classification system that goes from kingdom to species
Linnaeus
His observations suggested that species shred common ancestors rather than arising separately
Buffon
His findings suggest that more complex forms developed from less complex forms
