Mechanical digestion takes place mainly in the:
Question 31 options:
gall bladder and small intestine
small and large intestines
mouth and stomach
liver and pancreas
Solution
Mechanical digestion mainly takes place in the:
Mouth and Stomach
Here's why:
-
Mouth: The process of mechanical digestion starts in the mouth. The teeth break down food into smaller pieces through a process called mastication. The tongue also helps in this process by moving the food around while it is being chewed.
-
Stomach: After being swallowed, the food enters the stomach, where it is further broken down through a process called churning. In this process, the muscular walls of the stomach contract and relax, mixing the food with gastric juices and breaking it down into a semi-liquid substance.
The other options listed (gall bladder and small intestine, small and large intestines, liver and pancreas) are more involved in chemical digestion and absorption of nutrients rather than mechanical breakdown of food.
