Digestive System

The alimentary canal or the gastrointestinal (GI) tract.

Sugars such as glucose that are used as an energy source for your body. The brain and nervous system rely heavily on carbohydrates to function as well.

It is the systems, glands, and organs that break down food so that it can be used by the body. It also absorbs water and other liquids. It includes such anatomical parts as the mouth, tongue, teeth, esophagus, stomach, liver, gallbladder, pancreas, small and large intestines, appendix, colon, and rectum.

It fizzes then it dissolves!;D

Water is precious for nearly all bodily functions, so every single drop counts. If water weren't reclaimed from your digested food you would:

1) Have wetter feces. You'd let out slush when you go to the bathroom

2) Need to drink a lot more than the 1.9 liters per day that is recommended for a healthy person

There are complex hormonal interactions between the liver, pancreas, small intestine, and stomach, but here are the basics. The liver produces bile which is transferred and stored in the gallbladder and then secreted into the small intestine. There, it emulsifies fat, allowing it to be digested by lipase which is produced by the pancreas. The pancreas also produces amylase, which breaks down starches.

The Golgi apparatus. It creates lysosomes.Lysosome: Lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common in animal cells, but rare in plant cells.

Digestion starts from mouth as saliva present in mouth breakdown the starch present in food

Protein digestion occurs mainly in the stomach and also in the small intestine.

When protein food is eaten and enters the stomach, the hydrochloric acid in the stomach "denatures" the protein. This means it starts to break the protein down into short chains of amino acids joined together (peptide chains).

This is also when the the hydrochloric acid (HCl) also activates an enzyme called pepsin to participate in the break-down of the protein.

After this, the broken down protein enters into the small intestine where it is further broken down into the di-peptides (2 amino acids joined together) by pancreatic enzymes and then into its individual amino acids by other pancreatic enzymes.

The amino acids are absorbed through the small intestine and travel in the blood stream into the liver.

The main function of the left side of the human (quardrovascular) heart is to collect oxygenated blood from the lungs, then pump it around the body.

The main function is to get oxygen rich blood from the lungs and pump it to the whole body.

it is all yummy in your tummy...:) As the person who posted above me has stated, cheese is "yummy in your tummy." This is only semi-true. First, an enzyme in saliva called amylase digests any starch that is in the cheese, changing it into glucose, a carbohydrate (sugar). If you hold the cheese in your mouth for thirty to forty seconds or so, you will find that the cheese actually gets sweeter. This is because of the amylase turning the starch into sugar. Next, the food travels through the esophagus into the stomach. The epiglottis, a small strip of tissue, closes over the trachea, or windpipe, allowing food only to pass down into the esophagus. No digestion occurs in the esophagus. Peristalsis, the muscular movement that pushes food through the digestive tract, is the only thing that occurs there. An enzyme in digestive stomach acid called pepsin digests the protein in the cheese. The chyme, or semi-digested food, created in the stomach then moves to the small intestine. The small intestine is where the most chemical digestion occurs. This is also where most absorption of nutrients occurs. Villi, protrusions sticking out from the walls of the small intestine, allow the small intestine to have the greatest surface area possible, i.e., the most absorption in the least amount of time. The remaining chyme, a thin, watery substance, then enters the large intestine. The large intestine helps to maintain homeostasis by absorbing most of the water from the chyme. The water, absorbed into the body, helps blood to be liquid, among other things. Then, the remaining chyme, now called feces, enters the rectum, where it is stored. It is excreted out from the anus, which is another word for...well, you probably already know what it is. This is the complete "journey" *muffled laughter* that cheese, once ingested, takes through the body.

This region is called the pharynx.

Nutrients are substances that are absorbed by the body through the process of digestion.

It allows us to speak and keeps our food in between our teeth when we chew.

The tongue has three main functions. First, it carries on its surface the taste buds which send information to the brain about the nature of the food being eaten. It seems likely that the sensation of taste is not merely to make eating a pleasure, but also to act as a protective mechanism designed to cause the rejection of noxious (harmful) foods.

Secondly, the tongue plays an important part in the process of digestion. It enables the food to be moved about the mouth and to be placed in a position where it can most effectively be ground down by the molars. When the contents of the mouth are ready to be swallowed, the tongue forms them into a ball, or bolus, which is moved toward the pharynx at the beginning of swallowing.

Finally, the tongue is concerned in speech. By assuming different positions in the mouth it alters the shape of the air passage through which pass the sounds made by the vocal cords.

Metabolic panel may refer to either a basic metabolic panel (BMP or chem-8) or comprehensive metabolic panel (CMP or chem-14). A BMP is a blood test which measures the levels of 8 chemical compounds including sodium, potassium, chloride, bicarbonate, blood urea nitrogen, creatinine, glucose and calcium. A CMP is a blood test which measures all the aformentioned compounds in addition to alkaline phosphatase (ALP), total protein, albumin, AST, ALT and total bilirubin. eGFR refers to the estimated glomerular filtration rate which is usually calculated in the medical setting using the MDRD equation using the patient's age, gender, race and serum creatinine levels.

The following are some benefits of ultimate colon cleanse; Making the digestive system functions well, Preventing the hard stool or constipation, increasing the energy and Improving one's concentration.

Peristalsis. The movement of muscles bringing the food to the stomach.

there arefour points:

1.presence of villi gives large surface area for absorption

2.villi consist of extensive network of blood vessels which allows max assimilation and absorption

3.the length of the small intestine is so long and the digestion is a slow process, thus by the time the food or chyme reaches the end of the small intestine, its completely absorbed

4.intestinal juices present in small intestine speed up the absorption

-> write this in exam and you will pakka get full ;D

I believe they are pepsin, hydrochloric acid, and gastric acid. Pepsin digests proteins and breaks them into protein fragments. It can only work in acidic environments. Many people believe that the stomach acid breaks down food, but it is actually the pepsin that is activated by the acid.

because as it enters to the oesophagus it should really be digested or else or organs won't work properly

the above answer is correct, but can be improved. most foods must be digested forst, so that they can get into the cell. cells are very small and most foods are too big to even get through the cell membrane. therefore, the food must break down so they can fit through the cell membrane and proceed into the cell.

For example if you have had too much acidic food or drinks then if you take a capsule for example alka seltzer it should lower the pH in your stomach and bring the pH to a good suitable level.

Pepto Bismol can be a good way to go.

yes some fish have intestines up to 1 meter long

the fly is smaller
