What else can I help you with?
Is absorption mechanical or chemical digestion?
does absorption occur when mechanical or chemical digestion
Is absorption mechanical or chemical?
does absorption occur when mechanical or chemical digestion
What organ does mechanical digestion occur in?
Stomach and Mouth
Is pharynx a mechanical or chemical digestion?
The pharynx is not directly involved in digestion. It is a part of the digestive and respiratory systems, serving as a passageway for food and air to travel through. The process of digestion involves mechanical and chemical actions that occur in organs like the mouth, stomach, and intestines.
Is the small intestines chemical or mechanical?
The small intestine completes the process of chemical digestion.
Do enzymes occur in mechanical or chemical digestion?
think so
What type of Mechanical digestion takes place in your mouth stomach and small intestines I?
Chemical and mechanical ingestion take place in the mouth. Chemical and mechanical digestion also take place in the stomach. Chemical digestion takes place in the small intestine.Ingestion, digestion then absorption.In the mouth, both chemical digestion and mechanical digestion happen. The mechanical part is your teeth crushing the food into smaller pieces. The chemical part is when the salivary glands give off a special fluid that contains enzymes. When food enters the stomach, an enzyme is released that helps to digest food chemicaly. The muscles in the stomach also digest food mechanicly. Lastly, the small intestine completes the chemical and mechanical digestion of food. The small intestine takes out all the useful matirial and sends it to the cells as tiny molecules that the cells use in cellular resparation.Baisicly, they all use chemical and mechanical digestion.
What areas of the body does mechanical digestion occur?
mouth,stomach and small intestine
Where does mechanical digestion and chemical digestion occur along the digestive tract?
Mechanical Digestion happens in the mouth where your food is physically broken down. Chemical digestion happens in your intestines, where enzymes break down and absorb nutirients
Would biting a sandwich be a mechanical or chemical digestion?
Biting a sandwich involves mechanical digestion, as it breaks the food into smaller pieces through the action of teeth. This process increases the surface area of the food, making it easier for enzymes to later facilitate chemical digestion in the stomach and intestines. Chemical digestion would occur when enzymes begin to break down the food's components, such as carbohydrates and proteins.
How does mechanical digestion in the small intestine occur?
Mechanical digestion involves breaking down food molecules without changing the chemical nature of the molecules in the food. No chemical bonds are broken in mechanical digestion. Tearing forces (e.g. teeth) or muscular movements (e.g. the stomach) can assist mechanical digestion. Chemical digestion, which requires enzymes, involves breaking the bonds within food molecules and thereby producing products that are chemically different from the substrate (reactant). The smooth muscle layers of the small intestine are not set up for mechanical digestion. There are only two layers of smooth muscle in the muscularis externa of the small intestine: an inner circular layer and an outer longitudinal layer. These two muscles are ideal for peristalsis. In the stomach, however, there is an additional third layer in the muscularis externa (an oblique layer). These three layers can move the contents in the stomach around in many different directions. The stomach, therefore, is much better suited for mechanical digestion.
Most of the chemical digestion occurring in the?
most chemical digestion occur starting from duoduenum, small intestine. starch start from saliva in mouth, protein in stomach.
