Answer:
Digestive system.
Step-by-step explanation:
The liver is one of the most important organs of the digestive system for digestion because it has the function of metabolizing and storing nutrients, which are only ready to be absorbed and used by the body after passing through it.
The liver is considered an organ, but at the same time it is a gland, about 20 cm wide and usually weighing over 1 kg. It is located in the upper right abdomen very close to the stomach and is subdivided into 4 lobes: straight, left, caudate and square.
