What is the final step in the digestive process?

The final step in the digestive process is defecation. This stage occurs after the food has been ingested, mechanically broken down, and digested into smaller molecules that the body can absorb.

Once the nutrients are extracted during absorption, what remains is the waste product, which comprises undigested materials and byproducts of digestion. Defecation is the process where this waste is eliminated from the body through the rectum and anus, thereby completing the digestive cycle.

This final stage is crucial for maintaining the body's homeostasis by ensuring that waste does not accumulate, assisting in regulating the body's internal environment by expelling materials that are no longer needed.
