Final answer:
Option C, 'It acts as a reservoir for bile' is not a function of the liver; this is the role of the gallbladder. The liver produces bile, detoxifies substances, stores glucose, and produces blood-clotting factors.
Step-by-step explanation:
The question asks which of the following is NOT a function of the liver. The correct option here is C. It acts as reservoir for bile, as this is the function of the gallbladder. The liver does filter toxic substances, create glucose stores, and produces substances for blood clotting.
- The liver produces and excretes bile, which is required for the emulsification of fats during digestion. This bile is either sent directly to the duodenum or stored in the gallbladder, the latter being the organ that actually acts as a reservoir for bile.
- Detoxification is another key function of the liver, as it breaks down toxic substances, including medications, into less toxic and more easily excretable forms.
- As for metabolic processes, the liver plays a role in storing glycogen (glucose stores) and contributes to glucose metabolism along with other substances.
- Moreover, the liver is crucial for the production of blood-clotting factors such as fibrinogen, which further highlights its role in hemostasis.
