What is the meaning of the root "chol/e"?

The root "chol/e" specifically refers to "bile" or "gall." This terminology is commonly used in medical contexts involving the liver and digestive system, where bile plays a crucial role in the emulsification and digestion of fats. Bile is produced by the liver and stored in the gallbladder, illustrating the direct connection of this root to both the biological substance and its location in the body.

The other roots indicated in the choices pertain to entirely different bodily components. For instance, the root associated with blood has separate contexts, relating primarily to hematology. The term for the heart derives from different root words that do not overlap with those that signify bile. Also, enzymes are indicated by distinct roots that reference catalytic proteins, again unrelated to the term "chol/e." This clarity reinforces the understanding of medical terminology by demonstrating how roots translate into specific anatomical or physiological meanings.
