Most mechanical digestion takes place where?
In the Mouth then the second is the Stomach
Is pharynx a mechanical or chemical digestion?
the pharynx act is a connecting tube from the mouth to the stomach providing mechanical propulsion
What body parts is not involved in mechanical digestion?
Chemical digestion takes place in the stomach, the intestines, (saliva or enzymes) these parts of your body also use mechanical digestion.
Contrast mechanical digestion with chemical digestion and give an example of each?
Physical digestion is, basically, "mashing." The food is ground up (by the teeth), mashed into a paste (by the stomach), and so forth. It's mixed with other foods in the process, but no new molecules are produced. Chemical digestion involves chemical reactions, and new molecules ARE produced. The action of enzymes in saliva, gastric juices, and so forth is a form of chemical digestion.
How are chemical and physical digestion alike?
Physical Processes:Ingestion is the placing of food into the mouth. Mechanical digestion is the mastication of food and the churning of the stomach. Egestion is the removal of undigested materials from the digestive tract through defecation. Underlying all these processes are the muscle movements involved in swallowing and peristalsis.Chemical Processes:The digestion of starch to maltose by salivary amylase, the actions of all digestive enzymes, the emulsification of lipids by bile salts, the effects of the hydrochloric acid secreted by parietal cells of the stomach lining etc.Physical digestion includes things that involve mechanical motion, like chewing.Chemical digestion occurs when a chemical reaction causes the breakdown of food molecules. This occurs in several places, such as with the enzymes in your saliva and in your intestines.Chemical digestion breaks down food into smaller particles to be used as nutrients for the rest of the body. Mechanical digestion breaks down food into small pieces that are churned in the stomach and the intestines to be used as nutrients for the rest of the body, but some food may end up as waste.In me chemical digestion, foods are physically broken down into smaller pieces. In chemical digestion, chemicals produced by the body break foods into their smaller chemical building blocks.Chemical vs Mechanical DigestionThe digestive system of human body is made of vacuous organs connected with long and twisted tube from the mouth to the anus. This is also interlinked with various other organs that help the body to break the food particles and helps to absorb the nutrients. Organs like mouth, esophagus, stomach, small intestine, large intestine and anus play an important part in the process of digestion.When we consume food, the body needs to break down the food into smaller molecules of nutrients for the system to absorb the nutrients into blood streams. This would be carried to all the cells present throughout the body. Digestion process could be divided into mechanical and chemical digestion.Mechanical digestion is a process that begins the moment the food particles reach the mouth. The process of taking the food from mouth to the body is called ingestion. The teeth initiates the mechanical digestion by grinding the food and this process is also called as masticating.When initiating the chemical digestion process, the saliva secreted helps in softening the food into semi-solid lump. Salivary amylase enzyme helps in digesting the carbohydrates and mucus. This way the food particles are made finer for swallowing and chemical breakdown in the digestive track. The food thus made into semi solid lump is then pushed through the throat and esophagus, a hollow tube that connects throat and stomach.On reaching the stomach the food goes through a series of chemical and mechanical treatment. Inside the stomach mechanical digestion called peristaltic contractions helps to churn the food bolus. The chemical process mixes the bolus with digestive juices released by the stomach lining cells. The food particles go through hours of digestive process passing through various stages of chemical digestion.The processed food is moved into rectum by small intestine. Then the food gets fermented inside large intestine by the gut bacteria. This aids in digesting the unfinished projects of small intestine.There are four important hormones that help in regulating the digestion process.Gastrin '" gastric glands stimulates pepsinogen and hydrochloric acid on arrival of food inside stomach.Secretin '" this signals secretion of sodium bicarbonate in pancreas. Secretin helps in controlling the acidity of the chime.Cholecystokinin '" this helps in secretion of digestive enzymes in pancreas. This also aids in emptying the bile in gallbladder. Cholecystokinin is produced when the digestion process needs to handle fats from chime.Gastric inhibitory peptide '" this helps in decreasing the churning process. This also helps in producing insulin secretion.Even though the mechanical and chemical digestion processes are very important for the human digestive process, chemical digestion is considered more important. This is due to the complex procedure involved in Chemical digestion.Summary:1. Mechanical digestion refers to the digestion process that breaks the food into smaller particles.2. Chemical digestion is the process where acids, bases and enzymes released into the digestive track responds to semi-solid food lumps.3. Chemical digestion is more important than mechanical digestion as this is how we get our energy.Mechanical digestion is the actual chewing and breaking down of food, and chemical digestion is when one substance is turned into anotherMechanical digestion occurs in the mouth, when the teeth (and tongue) break down food into smaller pieces.Chemical digestion also starts in the mouth, when digestive enzymes begin to break down the food and continues in the stomach where gastric juices continue the job of breaking the food down.Mechanical digestion is when food is broken down in the mouth so you can think of your mouth being mechanical..... Chemical digestion is when you food is broken down by chemical enzymes so you can think I'd chemical as like erosionPhysical Processes:Ingestion is the placing of food into the mouth. Mechanical digestion is the mastication of food and the churning of the stomach. Egestion is the removal of undigested materials from the digestive tract through defecation.

I thinkchemical digestion is when chemical break down food.Mechanical => ChewingChemical => HCl in Stomach
Churning of the stomach is an example of what type of digestion?
mechanical
Where is the mechanical digestion competed?
Mechanical digestion in humans is completed in the stomach.
What does mechanical digestion mean?
Mechanical digestion happens in only in 2 of your digestion organs mouth and stomach. Mechanical digestion is the mechanical way you digest your food for example when your eating your teeth are mechanical digesting your food by making your food smaller by chewing on it your not changing your food in any way that only happens chemical digestion is happening.Another example of mechanical digestion is in your stomach when the food is bong to the stomach your stomach is squeezing mushing up the food to make it smaller (your stomach is made out of 3 lairs of mussel's which squeeze in all 3 different direction's).
Breaking down of food by churning in the stomach is an example of digestion?
The breaking down of food for the purpose of nutrition is called, "Digestion".
Where does chemical and mechanical digestion take place?
what is responsible for chemical digestion in earthworms
Most mechanical digestion takes place where?
In the Mouth then the second is the Stomach
Where do most mechanical digestion takes place?
In the Mouth then the second is the Stomach
Much of mechanical digestion takes place in the?
Stomach
What are the Organs where mechanical digestion take place?
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.
What does the churning action of the stomach wall accomplish?
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.
