Digestive System

Amylase is an enzyme that breaks down polysaccharides like starch into its constituent monosaccharides like glucose. This enzyme works best in environments like the mouth and small intestine where the pH is about 8. Amylase is secreted by your salivary glands for starch digestion in your mouth and by the pancreas for starch digestion in your small intestine. Amylase does not work in low pH environments and I think may be destroyed if the pH is low enough. This means amylase does not function and may even be destroyed in your stomach.

they are both receiving and producing & what they produce are waste materials.

Bile is produced in the liver and stored in the gall bladder. The presence of lipids in the duodenum causes the release of bile. Ultimately the liver and gall bladder control the release of bile.

The pancreas secretes digestive substances into the small intestine to help digest certain kinds of nutrients.

I assume you mean work? The digestive system begins with the tongue, it contains saliva which is a weak base acid which helps break down food in conjunction with your teeth and tongue. Once swallowed the food enters the stomach. The stomach contains a strong acid which breaks down food further into a liquid that the stomach lining can absorb. The stomach absorbs some and send the rest into the large intestine which breaks it down more and crushes it into large globules all the while coating it with a enzyme to break it down and make it more soluable for the small intestine to pass easier. Once in the small intestine it passes through into the rectal cavity where we pass it as feces.

Alternately. If the food is a liquid it travels into the kidneys where it is stripped of most harmful substances. It bypasses the intestinal tract and goes directly into the urinary bladder to be excreated.

The liver receives the bulk of the water soluble nutrients.

Little absorption occurs in the oral cavity, esophagus, and stomach. The small and large intestines are where most absorption takes place. The blood flows from the intestines back to the liver via the portal vein.

the mouth chews the food and mixes the food with saliva to begin it's break down. Next, the food goes down the esophagus and to the stomach. In the Stomach, food is mixed with digestive Juices and broken down even more. Then, the food travels through the small intestine and the nuitrients is taken out of the food and released to your body. After that, food enters the large intestine and any nuitrients that were not taken in the small intestine are absorbed here. Last, what is left over is stored in the rectum so the waste can be gotten rid of

hydrochloric acid produced by parietal cells converts pepsin to pepsinogen

Such waves of contractions are called as peristalsis. This is a regular feature in the digestive tract. When you eat the food, this process is more remarkable. There are local never plexuses that control the regular moments. There is the autonomic nervous system related to hypothalamus of the brain, which also control such movements. You have very good videos on the YouTube about the peristalsis.

The better way to do it is to go to the nurse or call your mom or if you want go to the bathroom if you fell you going to throw up if it just a tummy ache relax and drink a little of water and if it still hurts don't eat nothing at lunch but if you already did then that may be the cause

1) The rate of epithelial stem cell division declines.

2) Smooth muscle tone decreases.

3) The effects of cumulative damage become apparent.

4) cancer rates increase.

5) changes in other systems have direct or indirect effects on the digestive system.

Starch is a complex carbohydrate or polysaccharide, which consists of many monosaccharide molecules (glucose) joined together.
Since the cell in the body has partially permeable membrane, it cannot absorb big size molecules, such as starch and protein.
Hence, starch needs to be broken down to glucose before it can be absorbed into the cells of the body.

Because saliva is a very good healing liquid. if you cut yourself and put saliva on it, it would heal much quicker.

No, has nothing to do with digesting food. it's your bodies outer covering.

The major site of nutrient absorption is the small intestine.

The villi in the small intestine are small finger like projections, which increase surface area for the absorption of nutrients. They is richly supplied with blood vessels, which get nutrients from here and transport them to the rest of the body.

In my textbook it says that Alexis st Martin was his patient, St martin had been shot but the wound never healed and a hole was left. so Beaumont used this to disscover things about the digestive system.

mechanical and chamical

Lysosomes hope that helps! :)

The mechanical digestion processes in the large intestine is commonly referred to as peristalsis. The colon is the last stop in the digestive system and this where liquids are extracted from non-nutritive food waste before excretion.

The stomach stretchy muscular sac holds food.

You will get constipation
