Control of Organisms

Multicellular organisms need to coordinate the functions of all of their parts.

• Homeostasis is the process of keeping everything in the body balanced and working properly.

• Feedback mechanisms are a way to respond to stimuli and maintain homeostasis

• The Nervous System allows communication throughout the body using quick electrical signals

• The Endocrine System enables slower, but longer lasting control by making hormones that circulate in teh blood
