True. Smooth muscles in the stomach play a crucial role in mechanical digestion by contracting rhythmically to churn and mix the food with gastric juices. This process helps break down food into smaller particles and facilitates the enzymatic digestion that follows.
Peristalsis. The movement of muscles bringing the food to the stomach.
Saliva, amylase, mechanical and chemical digestion, muscles, mucus, stomach acid.
Mechanical digestion in humans is completed in the stomach.
The stomach has muscles that squeeze and mix food as well as acids that break it down. The stomach, then, performs both mechanical and chemical digestion.
what is responsible for chemical digestion in earthworms
The stomach has muscles that squeeze and mix food as well as acids that break it down. The stomach, then, performs both mechanical and chemical digestion.
Stomach
In the Mouth then the second is the Stomach
Mechanical digestion is aided by the action of stomach muscles. These muscles contract and relax to churn and mix food with gastric juices, breaking it down into smaller particles and facilitating chemical digestion. This process helps in the effective mixing of food with enzymes and acids, enhancing nutrient absorption later in the digestive tract.
There is the small intestine, stomach, and the mouth, and that is all that i can think of. Hope this answer helps you people out there looking for three of the organs for mechanical digestion. But if not....... well that sucks for you.
The churning action of the stomach wall accomplishes mechanical digestion. Mechanical digestion begins in the mouth and along with chemical digestion, ends in the small intestine.
The grinding of food in the stomach is primarily a mechanical process. Stomach muscles contract to mix and break down food into a pulpy mixture, known as chyme, through a process of churning. While chemical digestion also occurs due to gastric juices, the physical action of the muscles is what primarily facilitates the grinding.
