Digestive System

the stomach cus acids help break down the food and the mouth to because the saliva has chemicals that help too.

Chewing is the very first step in the process of digestion and the degree to which we chew our food well is important as it sets the stage for all the other processes of digestion and elimination. While we chew, saliva is added to the food we chew and the process of digestion has begun even before the bite of food travels to our stomach. Within the stomach digestion continues with acids acting upon the chunks of food we have swallowed. If the food in our stomach has not been chewed well enough the acids will do an incomplete job of breaking down the chunk. Soon enough the food in the tummy will be booted out and into the small intestine for continued digestive activity. Unfortunately, the small intestine has no idea how to handle these remaining large chunks and you may experience cramps and other complaints from deep within your gut.

Listen to your Mother and chew your food well!

The digestive system. The liver also has other functions as does the pancreas. The pancreas secretes pancreatic enzyme which is responsible for the breakdown of protein but it also secretes insulin so that we can get energy from glucose making it a part of the endocrine system or glands. The liver de-toxifies all of the blood that carries absorbed nutrients from the digestive system. This blood is then sent to the heart where it rejoins the circulation. The liver also makes bile and sends it to the gall bladder where it sits until we eat a fatty meal. It is then secreted and it breaks down fat rather like fairy liquid does, it emulsifies it. The liver converts excess glucose to glycogen and stores it ready for when the blood sugar falls unexpectedly when it converts it back to glucose again. It synthesises pro-thrombin which is responsible for normal blood clotting. It also synthesises vitamin a and together with vit b12, d, and k these are stored in the liver. Being the largest organ and having the most varied of functions the liver creates a lot of heat and it is one of the factors in keeping us warm. Hope this helps, sorry I went on.

Made in liver, Stored in gall bladder,transferred through bile duct to the food to the small intestine.

the small intestine

No, the pancreas is involved in chemical digestion, as it secretes enzymes which catalyze the breakdown of food molecules.

The digestive and excretory system both help facilitate materials to their designated destination. The digestive system breaks down organic material to nutrients and unnecessary materials. The excretory system takes those unnecessary materials and remove them from the system.

The pancreas is the main digestive enzyme-producing organ in the body.

are there choices?

the tracheal system of insects provides direct exchange between the air and body cell, therefore these insect like a grasshopper does not have respiratory system in its body.

1. Exercise regularly

2. Eat Smaller meals throughout the day

3. Eat breakfast if possible

4. Drink hot fluids with meals and throughout the day

5. Chew food thoroughly to aid in digestion

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.
