b. mouth: esophagus: stomach: small intestine: large intestine
c. mouth: stomach: esophagus: small intestine: large intestine
d. mouth: stomach: esophagus: large intestine: small intestine

Answer 1

The order of organs in the GI tract for digestion and absorption is mouth, esophagus, stomach, small intestine, and large intestine.

Step-by-step explanation:

The order in which each of the organs of the GI tract work to achieve the process of digesting and absorbing nutrients is:

1. Mouth: Food enters the mouth where it is chewed and mixed with saliva to begin the process of breaking it down.
2. Esophagus: Once swallowed, food travels through the esophagus, a muscular tube, to reach the stomach.
3. Stomach: In the stomach, food is further broken down and mixed with gastric juices to form chyme.
4. Small Intestine: Chyme enters the small intestine where it is digested and absorbed into the bloodstream.
5. Large Intestine: The remaining undigested material enters the large intestine where water is absorbed and waste is formed, which is then eliminated through the rectum and anus.
