Digestive System

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

Prevents food and water entering the lungs

The nutrients are taken out of the food while it is being digested, and going into your bloodstream, which flows around your body and feeds the nutrients to different parts of your body.

It's a semi solid mixture of food we ingested. it contains various chemicals and enzymes to start up various processes in digestion and it also serves as a energy supply to the body.

large intestine

Well water is not digested but i actually have no idea what I'm saying so forget this answer :)

Unicellular eukaryotes achieve intracellular digestion through the process of endocytosis, phagocytosis, and use of food vacuoles and lysosomes.

A paramecium is an example of an organism that uses intracellular digestion vs. humans which utilize extracellular digestion.

Chewing food before swallowing has four important roles:

1) Preparation of bolus to facilitate swallowing

Chewing mechanically breaks down large complex food molecules into smaller simpler molecules so that there is an increase in surface area for the action of salivary enzymes (e.g. amylase) to begin digestion (however, digestion in the mouth is minimal compared to the SI).

2) Chewing stimulates salivary flow and hence allows the food to be mixed and lubricated which makes swallowing easier

3) Chewing releases chemicals from food which stimulate taste bud receptors

4) Chewing helps to maintain the structural integrity of the oro-facial tissues (it is through the process of chewing that exercise of our jaws helps to keep them strong and healthy)

Chewing before swallowing makes digestion and absorption more efficient as the lubricated bolus is a much smaller mass of food and so nutrients extracted can be absorbed more quickly. Chewing is particularly important for tough food such as red meat than it is for fish, eggs, cheese because these can be broken down in the SI aswell. Red meat is more difficult to break down in the GI tract and this makes it harder to absorb nutrients from it.

Hope this helps?

Yes they do. the protein has to be digested in the stomach before absorbed there.

The rectum is the final part of the digestive tract, and is where faeces, the waste products of digestion, are stored until they are expelled from the body. All the waste will then leave by the anus.

Your liver produces bile, which is stored in the gall bladder until it's triggered by eating foods that contain fat. Bile is then released into the small intestine where it works like a detergent to emulsify the fats into smaller droplets. This makes it easier for pancreatic lipase to break down the fat. If people who don't have a gall bladder eat a lot of fatty foods, the fat isn't digested and acts as a laxative.

Produce vitamin k and vitamin b

Yes, both chemical and mechanical digestion break down food into smaller units.

NO
