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
