Q

large, complex organ located in the upper right quadrant of the abdomen.
Functions:
- Filtering blood: The liver removes toxins and waste products from the blood.
- Producing bile: Bile is a fluid that helps to break down fats in the small intestine.
- Storing glucose: The liver stores excess glucose as glycogen.
- Synthesizing proteins: The liver produces many proteins, including albumin and clotting factors.
