What are the major body systems involved in maintaining homeostasis? - ✔️✔️lungs,
pancreas, kidneys and skin.
homeostasis - ✔️✔️the ability to maintain a stable internal environment
negative feedback - ✔️✔️the body senses a change and activates mechanisms that
negate that change
example of negative feedback - ✔️✔️sweating
anatomy - ✔️✔️study of structure or form
positive feedback - ✔️✔️the body senses a change and activates mechanisms that will
amplify that change
example of positive feedback - ✔️✔️childbirth and blood clotting
