What are negative feedback mechanisms in homeostasis and how do they work?

• Processes that have no impact on maintaining the body's internal environment

How do the kidneys contribute to maintaining homeostasis?

• By producing insulin and glucagon to regulate blood sugar levels

• By controlling the production of red blood cells in the bone marrow

• By secreting digestive enzymes to break down food in the stomach

• By regulating the balance of water, electrolytes, and acid-base in the body, as well as removing waste products from the blood.
