Final answer:
The procedure known as gastric lavage involves washing out the stomach using a nasogastric tube. The cecum is the part of the large intestine that connects to the appendix. Propulsion is a process that happens throughout the alimentary canal.
Step-by-step explanation:
Washing out the stomach through a nasogastric tube is called gastric lavage. This is a medical procedure wherein the stomach is cleansed of its contents as an emergency procedure (for example, in cases of overdose or poisoning) or before surgery.
The cecum is the part of the large intestine that attaches to the appendix. Colonoscopy, endoscopy, and appendectomy are different procedures: a colonoscopy is an examination of the large intestine, an endoscopy involves examining the interior of a bodily organ with a camera, and an appendectomy is the surgical removal of the appendix. Lastly, one process that occurs throughout most of the alimentary canal is propulsion, which is the movement of food through the digestive tract.
