Question

reading tool make connections the liver plays a key role in maintaining homeostasis in the human body. it maintains glucose levels when blood glucose gets too high or too low. describe a second way in which the liver promotes homeostasis.

Explanation:

The liver helps in detoxification, removing harmful substances like toxins and drugs from the blood. It also processes and excretes bilirubin (from red blood cell breakdown) and metabolizes ammonia into urea (less toxic) for excretion, maintaining blood chemistry balance. Another way is in protein metabolism (producing plasma proteins like albumin) or lipid metabolism (regulating fat storage/transport), all aiding homeostasis. For example, detoxification: the liver filters blood, breaks down toxins (e.g., alcohol, metabolic wastes) into less harmful forms for elimination, preventing toxin buildup that could disrupt bodily functions.

Answer:

One second way the liver promotes homeostasis is through detoxification. The liver filters harmful substances (e.g., toxins, drugs, metabolic wastes like ammonia) from the blood, metabolizes them into less toxic compounds (e.g., converting ammonia to urea for excretion, breaking down alcohol), and eliminates these from the body, preventing toxin - induced disruptions to bodily functions and maintaining blood and tissue chemistry balance. (Other valid ways: regulating protein/lipid metabolism, producing plasma proteins, storing/releasing vitamins/iron, etc.)
