Digestive System

The finger-like projections in the small intestines are called villi & they are present in the small intestine to increase the surface area of the intestinal wall. A greater surface area allows the intestines to absorb more nutrients from the digested food into the blood stream. Villi are prominent in the small intestines because this is where majority of the absorption of nutrients occur. Villi also play a small role in the digestion of food.

loser answer it for me

The first step in the digestion of starch is the mouth mashing up the starches. Next, the stomach acids break down the starches. Then it passes to the small intestine where dextrinase and glucoamylase further break down the starches. Several enzymes are released from the pancreas into the small intestine to finish breaking down the starches.

All of them.

The Epiglottis

The first common, and most serious, cause of sulfur burps is an infection from Helicobacter pylori or Giardia. Helicobacter pylori is a bacterium that can cause serious infection and ulcers within your stomach. Giardia is a parasite that makes its home in your lower intestine and reproduces to cause serious stomach problems. The most common ways to introduce either of these infections is through unclean water sources or poor hygiene and oral-fecal transmission. Sulfur burps can be a symptom of both of these infections.

Some food may also cause sulfur burps. This is especially true in those with diets high in protein. The main culprit in food-related sulfur burps is hydrogen sulfide. If your stomach takes longer than normal to process and expel a meal high in protein, the lingering food can actually start to build up acid and cause a chemical reaction that creates hydrogen sulfide. This can also explain why someone suffering from sulfur burps may feel bloated. In these cases, the sulfur burps usually go away once the lingering protein and hydrogen sulfide is expelled.

Possible Answers: The epithelial cells lining the stomach have specialized defensive properties against stong acids

Mucous found within the stomach

The stomach's epithelial cells are defenseless against stong acids

The stomach has a pH of 7 when digestion isn't taking place

Correct answer: Mucous found within the stomach

Explanation: A layer of mucous forms between the epithelial cells of the stomach and the acid within the stomach. This mucous is secreted by mucous cells lining the stomach. When the mucous layer is broken down, certain complications can take place (e.g. stomach ulcers).

Digestive bacteria reproduce by a process called Binary fission, which simply means one cell divided to become two cells, then those two cells become four, four become eight, etc the same way you do. Skin is the first line of defense and it work as physical barrier for all the microbes and particle. Skin has many secretory products which kill the bacteria also.

Food typically takes about 24 to 72 hours to move through the entire digestive tract, depending on various factors such as the type of food consumed and individual metabolism. After ingestion, food spends a few hours in the stomach before moving into the small intestine, where it can remain for 3 to 5 hours. It then enters the large intestine, where it may take 12 to 48 hours to be eliminated. Overall, the entire process can vary significantly from person to person.

Urination. If you are looking for a little bit more, inside your body, you use the vitamins and such in the things you drink. Then water, the liquid wastes, and something called urea (if the wastes and urea aren't the same thing, I'm not sure) combine and make urine, which is taken to your bladder and stored until it is full. Then you urinate and that is when the water comes out.

---- Gastric acid is mainly composed of hydrochloric acid, 2 protein digesting enzymes (Pepsin and Rennin), as well as mucus.

You are probably referring to the stomach.

Food travels down the esophagus or intestines by a muscle movement called "Peristalsis" that constantly pushes the food down into the stomach.

Nothing is broken down in the anus because it is where the waste/stole is passed.

Mouth & beak: Gathers and breaks down food

Esophagus : the tube from the mouth leading to the stomach

Crop: Food storage and moistening

Proventriculus: Glandular stomach (HCI and gastric juices) enzymatic

Gizzard: Muscular stomach, mechanical breakdown of food.

Small intestine: Enzymatic,digestion and absorption.

Large Intestine: Bacterial activity, water absorption and waste storage

Cloaca: Common chamber for GI, urinary tract and ovum

Digestion takes place mainly in the small intestine by pancreatic enzymes eg trypsin or pancreatic lipase. but also a small amount takes place in the stomach by stomach enzymes eg pepsin or gastric lipase. of the lipase's pancreatic lipase is far more important in digestion of fats that gastric lipase. note that small amounts of starch digestion also takes place in the mouth due to the actions of amylase which is found in saliva. This action is short lived as the amylase action is abolished by the low pH of the stomach. No digestion takes place in the large intestine (aka the colon) as this is mainly for absorption of water and electrolytes.

By secondary active transport with Hydrogen.

Part of vomit will always be stomach acid because it's naturally produced in the stomach as a part of digestion. However, throwing up blood can be a sign of damage to the trachea/esophagus/stomach/liver/duodenum, ruptured stomach ulcers, liver disorders.. the list is long. Basically if you throw up blood and your throat isn't hurting (like it's cut) get to hospital (quickly if any significant amount - ruptured ulcers can kill quickly). In any case - seek medical advice immediately.

It is asumed as no. Even when the amount of food decreases along the way to stomach, it is still a no, here are the reasons:

-- Digestion does not take place in the gullet as gullet does not produce any digestive juice.

-- The reason why there are a decrease amount of food in gullet is because you swallow down saliva and saliva is a form of digestive juice.

In addition, Another name for the gullet is "esophagus".

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.

More then likely, you have systemic candida. That is an overgrowth of candida albicans in your gut from poor diet. If you eat a lot of sugar, carbs, and processed foods that will cause it. Also, if you have been on antibiotics for a long time, that could be the culprit.

esophagus

if the food is already has gone through the stomach then it is chyme

digesting food is a chemical change because-

1)it is irreversible and permanent.

2)it involves heat change(heat energy is evolved).

3)the final products cant be changed into original form by simple physical methods.

4)C6H12O6=co2+h2o+heat energy

the food is then forced down the esophagus.
