Homeostasis and Feedback Loops

Homeostasis

• allows for a wildly fluctuating internal environment
• is impossible in vertebrates
• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation

a body system that controls growth and homeostasis by secreting hormones from glands.

• skeletal system
• nervous system
• endocrine sytem
• integumentary system

NGSS.HS-LS1-3

a body system that controls and coordinates all body activities through electric impulses/messages between brain, spinal cord and nerves.

• endocrine system 
• nervous system
• nerve
• neuron

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

Homeostasis in the human body is often maintained by a: 

• neutral feedback loop 
• solar feedback loop
• positive feedback loop
• negative feedback loop
