Final answer:
Chyme is the semi-liquid mixture of partially digested food and digestive juices produced in the stomach, correctly identified in option c). It is not related to stool until after it has moved through the digestive system and has had most of its water reabsorbed in the large intestine.
Step-by-step explanation:
The term chyme refers to the thick, semi-liquid mixture that food becomes after being processed in the stomach with digestive juices.
It is not solid stool, liquid stool, nor is it undigested food.
Thus, the correct answer to the question 'The nutritional physiology term Chyme literally means:' is c) Partially Digested Food.
In the digestive system, chyme is created in the stomach and then moves into the small intestine, where it mixes with bile.
Bile, produced in the liver and stored in the gallbladder, helps in emulsifying fats.
This process is essential for the digestion and absorption of fats.
The movement of chyme from the stomach to the small intestine is regulated by the pyloric sphincter.
Lastly, in the large intestine, the remaining water is absorbed from the chyme, transforming it into semi-solid feces, also known as stool, which is then eliminated from the body.
