It's simple it's your mouth. I know it might sound crazy but it's true. Inside your mouth you have teeth you crush and tear of meat, so that's mechanical. Your spit contains enzymes to convert starch into sugars, so that's mechanical.
Most of the digestion occurs (believe it or not) not in the stomach, but the smaller intestine.

The pancreas secretes digestive enzymes that help break down carbohydrates, fats, and proteins in the small intestine. This organ plays a crucial role in the chemical digestion of food.
Mouth: in saliva there is this amylase enzym to break it down to sugar(s)
The largest organ in the human body, our skin, is effectually, an excellent mechanical barrier. There are of course, some chemical and bacterial (normal flora) factors that play a part, but its mechanical function is its largest asset for sure. A break in the integrity of this mechanical barrier (i.e. an abrasion, laceration, puncture, incision, etc) provides an open door and an excellent opportunity for foreign bacteria and viruses to invade and potentially infect the host.
The small intestine is the organ responsible for both chemical digestion and absorption of nutrients from food. Enzymes and bile break down the food, while nutrients are absorbed through the small intestine's lining into the bloodstream for distribution to the body's cells.
The tongue is primarily a chemical sensory organ responsible for detecting taste molecules in food. It contains taste buds that send signals to the brain to interpret different flavors. The mechanical functions of the tongue, such as pushing and moving food around in the mouth during chewing and swallowing, are secondary to its role in taste perception.
Stomach and Mouth
mechanical digestion is when you are breaking down food almost by hand. you're breaking it down manually. an example of mechanical digestion is chewing. it begins in your mouth and ends once you swallow.
