Homeostasis & Feedback Loops
What is Homeostasis?
Homeostasis is the physiological state of the body in which your internal, physical, and chemical conditions are kept within a suitable range for living.
Organs Systems Involved in Homeostasis:
Nervous System
Brain, spinal cord, peripheral nerves, sensory organs
Endocrine System
Pituitary, thyroid, adrenal, pancreas, etc.
Muscular System
Skeletal, cardiac, and smooth muscles
Integumentary System
Skin, sweat glands, hair, nails
Excretory System
Kidneys, bladder, ureter, urethra
Reproductive System
Female: ovaries, uterus, vagina, mammary glands
Male: testes, sperm duct, penis
Tasks that Maintain Homeostasis in the Body:
Taking in nutrients, processing, and distributing them throughout the body, and disposing of waste
Synthesizing carbs, fats, and proteins
Sensing and responding to changes in temperate, pH, and physical sensations
Protecting body from injuries, infections, bacteria, and diseases
Reproducing, protecting, and feeding offspring

Watch this video about Feedback Loops and learn about some examples in the body.
