Digestive System

Both

To further clarify:

Mechanical: The stomach is a muscular sack. It contracts and relaxes, sloshing and squeezing the food inside to break it down and to ease the job of the 'chemicals'. Another example is how many birds swallow stones to enhance the crushing and churning in their stomachs.

Chemical: The conditions and enzymes within the stomach contribute to chemical digestion. Hydrochloric acid, for example, creates an acidic environment that denatures proteins; whilst enzymes such as pepsin react at a molecular level with peptides to cleave them apart.

maybe my answer is right

The alimentary canal allows for food to travel in one direction (because it is a complete digestive tract) which means that the organic materials from the food can be taken to specialized regions that digest it and take in nutrients.

Also, more food can be eaten while previously eaten food is still digesting.

The excess is stored as glycogen.

Gut movement is also known as peristalsis which, quite literally means the wavelike muscle contractions of the digestive tract. Peristalsis occurs for two main reasons:

1) To move the food along throughout the digestive tract so as to move it closer and closer to your anus for excretion.

2) To make sure the nutrients are being absorbed from the food as well as exposing it to the digestive juices secreted from your digestive system so that it may be entirely digested.

Yes it can although such measures are not standardized and subject to wide interpretation. In general, malodorous flatus may indicate higher colonization with intestinal microbes that produce more sulfur containing gases. Other than potential social awkwardness, this has little medical importance.

most of the digetion takes place in the small intestant

Roughage is not digested in human intestine. Also called fibers. That is a gift of 'God' to human being that you are lacking the enzyme. Which is necessary to brake the beta Glycosidic bond present in cellulose and other dietary fibers. Roughage gives bulk to the feces. So you have motion more frequently. This protects you from cancer of colon and rectum. By washing away toxic products. So 'roughage' is a must in diet.

No, the sigmoid colon is a part of the large intestine, and feces go through it.

In the lysosome.

After eating, your stomach requires blood to digest the food. Swimming takes the needed blood away from that initial digestion process causing undigested food to move through that first critical stage where most of the food is broken down.

Lysosomes

After food is chewed it takes 5-10 seconds for it to pass down the esophagus and into the stomach, where it spends 2-6 hours being partially digested. Final digestion and nutrient absorption occur in the small intestine over a period of 5-6 hours. In 12-24 hours, any undigested material passes through the large intestine, and feces are expelled through the anus.

The enzyme that breaks down starch is called amylase

Fats are not digested until they reach the small intestine.

Saliva contains an enzyme called amylase. The amylase breaks down the polysaccharide starch into a disaccharide called glucose.
