Solution

The part of digestive canal involved in the killing of bacteria is the stomach. The inner lining of the stomach secretes mucous, hydrochloric acid and digestive juices. The hydrochloric acid kills the bacteria which enters into the stomach along with the food that we have consumed and it makes the medium in the stomach acidic. Some amount of bacteria is also killed by the saliva.
