Digestive System
Digestive System is the category for questions regarding the breakdown and absorption of food-stuffs in our alimentary canal. Questions about the stomach and intestines can be included in this category.

lysosome
What are the four layers of the digestive tract?
Mucosa, Submucosa, Muscularis externa, and the Serosa
Why is the pH system in your lower intestine about 8?
Because the pH in the stomach is below 7, which makes it acidic. This high pH returns the food to a neutral pH, and also allows the enzymes within it to function properly.
What is the function of the liver and gallbladder?
The gallbladder stores and concentrates bile. The liver produces many functions with digestion, metabolism, immunity and the storage of nutrients within your body. There are tubes called bile ducts that carry bile through the liver and gallbladder.
food that your body has taken out all the nurtients of, aswell as some stomach juices, and other liquad. This is expelled out of the sphinkter
Is phosphate necessary in amino acids?
Phosphate is an important substrate and is needed for the production of ATP. It helps make amino acids, which build proteins.
What could happen if you swallow a toothpick?
If you swallow a toothpick, you should contact a medical professional.
Swallowing a sharp piece of a wooden toothpick is a common occurrence. However, in a number of cases it has proven to cause serious internal injuries. The pick can lodge in the digestive tract, blocking food flow, or even perforate the esophagus, trachea, stomach, or intestinal wall, with the potential for bleeding or infection. This can be more dangerous to babies or children.
Children should never be alllowed to play with toothpicks, especially plastic ones that cannot soften as wooden ones might if ingested.
What causes movement of food inside the alimentary canal?
Peristalsis - the wavelike motion of the intestinal wall smooth muscles that push the food forward.
How much vanilla do you use for upset stomach?
Personally I would not recommend vanilla for an upset stomach. Your first line of defense is simply water. However, I have obtained good results by eating cheese. Cheese can be very soothing. Your mileage may vary.
What part of the small intestine connects to the stomach mostly for chemical digestion takes place?
The duodenum is the part of the small intestine that connects to the stomach. The food moves through the pylorus from the stomach to the small intestine.
What is the process of absorption?
Adsorption is the process by which a gas dissolves into the surface of a solid, which will normally be metal.
There are actually two types of absorption.
Adsorption and Absorption
ABsorption actually happens in the digestive process.
How is diffusion used when cells remove carbon dioxide?
Carbon dioxide moves out of the cells from a higher to lower concentration across the cell membrane. Then the CO2 moves through the capillary wall across the diffusion gradient. The diffusion process is repeated at the capillary/alveolar junction.
Is Spoiling food physical or chemical change?
It is Chemical because when food spoils it gets the green mold growing making it inedable and food last I checked was edable.
Can the human body digest a metal corn cob?
No. The only metal we can safely digest is pure gold leaf.
ANS2:There are only a few metals that can be safely ingested because most have toxic effects. The process of digestion is the breaking down of materials into absorbable components. There are a number of metals that can be digested. The hydrochloric acid in the stomach can digest iron, aluminum, copper, zinc, all of the group 1 and 2 metals and salts of silver, lead and mercury. Digesting does not necessarily mean that the quantity of metal will be entirely digested.Say your hypothetical metal corncob (I hope it is hypothetical) is made of brass. Brass is an alloy of copper and zinc. It will be corroded by the stomach acid and produce copper and zinc chloride. Neither of those salts is particularly good for you and may irritate the intestines but will probably not be absorbed in quantities large enough to poison you. If the corncob was coated with lacquer, as most ornamental brass pieces are, the stomach acid cannot come in contact with the metal so it will not be digested.
The preceding answer claims that gold can be digested. On the contrary, it will not be affected by any digestive process in the human body. It will pass harmlessly through the digestive tract without being affected. Some alloys, such as stainless steel will be similarly unaffected.
To get a better answer to this question, find out what sort of metal your corncob is made from and ask about digesting that metal.
What role does alpha amylase have in the process of digestion?
Alpha amylase is an enzyme that breaks down long chain carbohydrates in the starch chain during digestion. Technically speaking, it hydrolyses alpha-bonds of large alpha-linked polysaccharides like starch and glycogen, producing glucose and maltose. It is most present in the saliva, where digestion actually begins, and pancreatic juice.
How does amylase make it possible for starch to be digested at body temp?
Amylase in an enzyme which is also a biological catalyst which reduces the activation energy needed for the hyrolysis of starch
