No. Something is really wrong if that happens.

Mechanical and chemical digestion. In mechanical digestion the teeth breakdown food into smaller pieces and in chemical digestion the salivary glands breaks down the food molecules.

Flatulence contains nitrogen, carbon dioxide, oxygen, methane, and hydrogen sulfide. These are created by the fermentation of undigested foods such as bean skins and veegtable fiber. The hydrogen sulfide and other compounds (mercaptan, butyric acid and carbonyl sulfide) make the released gases smell bad. Humans actually expel little methane compared to ruminants such as cows and sheep.

It's possible that the "bad" smell -- human's normal reluctance to deal with feces, etc. is evolutionary. The individuals repelled by this remain healthier, etc.

The stomach contains gastric acids to help break down foods.

I am not 100 % sure of this but I believe the digestive system goes from your mouth all the way to your colon so everything in between is a part of the digestive system.

No. Animals do not produce enzymes that hydrolyze cellulose. (From Master Bio - Chapter 41).

The proenzyme pepsinogen,on exposure to hydrochloric acid gets converted into active enzyme pepsin,the proteolytic enzyme of the stomach.Pepsin converts proteins into proteoses and peptones(peptides).

All mammals and reptiles have an esophagus. The esophagus extends from the end of the windpipe to the stomach and is part of the digestive system.

digestion starts in the mouth where the food is broken down by enzymes in your saliva. the the food passes down to the stomach where the enzymes are denatured. then the food molecules pass through to the small intestine when they are broken down by more enzymes. the products made from this are then absorbed by the small intestine wall or passed along out of the body.

The pharynx is the tube which food passes threw after it is chemically and mechanically digested in the mouth. This leads to the esophagus then to the stomach.

The digestive system is the process that enables us to physically break down the essential nutrients and liquids in food from an external environment into our internal environment. Through the physical and chemical processes in the digestive and gastrointestinal tract, the circulatory and digestive systems play an integral part of this process which is essentially for our body's energy and growth. The circulatory system absorbs, transports and distributes the broken down nutrients to our tissues and cells. And without the digestive process our tissues and cells would not receive the essential material that enables us to move, grow AND live. So the digestive needs the circulatory system and vice versa.

Taking a Digestive Enzyme can help with the digestion of fruits.

The small intestine is the largest in the digestive system because it has the largest surface area. The whole inside of the small intestine is covered in villi and micro villi and when spread out it would be about the size of 4 tennis courts! These villi and micro villi are there in order to allow the absorption of nutrients and gases into the circulatory system.

Yes, humans use some metals but they are not in the metallic form but in the ionic form. The best example is the ionic form of iron which is found in all red blood cells. This form carries oxygen to all the body cells.

Teeth help with breaking up all the food so your body can handle it and you wont choke.

adaptation of digestine is connected to large intestine having conjection if there is extra water

Stomach noise - such as rumbling, gurgling and growling - typically is due to normal digestion. Stomach growling can occur when you're hungry. But it can also occur after eating or between meals when food is passing through your intestines.

Hunger and appetite are controlled by a complex system of hormone-like substances primarily made by your digestive system. When you haven't eaten for a while, these substances are released and cause a part of your brain called the hypothalamus to "switch on" your desire to eat. A message is then sent to your stomach and intestines. This triggers muscle contractions and the release of acids and other digestive fluids - which causes the rumbling, grumbling sounds you hear - as your body prepares for you to eat. The thought, sight or smell of food also can trigger this response.

Sometimes excessive stomach noise can be a symptom of an underlying gastrointestinal disorder, such as irritable bowel syndrome. But in such cases, stomach noise usually is accompanied by other signs and symptoms such as bloating, cramping, diarrhea or excess gas.

No.

The stomach juices are way too acidic.

Chyme!! :))))))))

The trachea enables the flow of air from the external environment into the lungs to absorb oxygen and other gases.

The esophagus allows the body to ingest food for optimal nutrition and to maintain life processes.

Roughly one-fifth of all patients who undergo surgery for appendicitis are found to have a ruptured or perforated appendix. This can cause a condition known as peritonitis, which is an inflammation of the membrane surrounding the internal organs. The membrane is known as the peritoneum. Nowadays, peritonitis can be successfully treated with antibiotics, although there is a still a slight risk that an abscess may form in the abdominal cavity. If this happens, it will have to be carefully drained and the patient will be required to remain in hospital. Some people may develop extra internal scar tissue at the site of the removed appendix. This scar tissue is known as an adhesion. The adhesion may stick on to nearby segments of intestine resulting in obstruction of those segments. Obstructions may release themselves in a short space of time but can persist and result in complete obstruction of the intestine, which is a surgical emergency. Obstruction of the intestine following appendicectomy is not a common complication
