Answer:
Food that has been digested in the <u>stomach</u> is processed into a thick liquid called <u>chyme.</u>
Explanation:
The stomach can be described as a large, muscular organ where digestion of food takes place. The stomach effectively secretes enzymes to process and digest food. The nature of the stomach is acidic. Chemical digestion begins in the stomach. The muscles of the stomach contract in a periodic manner due to which food enters into the stomach. After the food has been digested, the food turns into a thick liquid called chyme.
