Well digestion starts in the mouth when you chew your food with your teeth. This is called mastication. When your chewing, saliva, which has enzymes to start to break down the food are added. The food flows down the esophagus to to stomach. The pancreas is connected to the duodenum(first part of the small intestine) via the pancreatic duct. It releases enzymes which further digest the food as it travels through the body. The gallbladder stores and releases bile. The bile causes fats to break up so that they are more easily digested in the small intestine. So after all of that I would say that the teeth aid in mechanical digestion by breaking up the majority of the food and to trigger the salivary amylase. If we didn't chew our food up no amount of enzymes from our organs would be able to properly digest our food. I go with D. Teeth

The teeth are primarily responsible for mechanical digestion, because mechanical digestion is the process of breaking large pieces into smaller ones without altering its chemical composition.

The teeth or mouth because this is where chemical and mechanical digestion occurs.

The process of digestion breaks down complex food molecules (such as the protein in steak) that the body cannot readily use into simpler, smaller molecules (amino acids) which the body can absorb and use to fuel other life processes. The digestive tract performs this mission like a machine. Each organ has a specific job and depends on the others to perform properly. In the mouth, initial physical break- down of protein begins. The stomach continues physical break-down and begins chemical break-down by secreting a substance called pepsinogen. It then converts pepsinogen into an enzyme called pepsin. This enzyme starts to break apart the protein into amino acids. Muscles in the stomach walls then move the food into the duodenum, the first part of the small intestine. The duodenum and pancreas work together to complete the chemical break-down of protein into single amino acid molecules with the help of another enzyme known as trypsin. Finally, the small intestine absorbs the amino acid molecules, allowing them to pass into the bloodstream. The blood then carries the amino acids to the rest of the body to rearrange into human proteins and use in building its structure. Each part of the "machine" of digestion must work properly in order for protein to be broken down into useful amino acids. and that machine is your stomach

mechanical...which one does the human need to move to digest something?

Pancrease and gallbladder secrete
Esophagus moves by itself

I'm guessing but I think it's teeth

D. Teeth
(That's in human beings. Other animals have other grinding mechanisms.)

teeth... others are involved in chemical digestion like the gall bladder and pancreas.

mechanical digestion

That indicates to me "teeth". ????Organ????

Others indicate "Chemical".
