Bile (or gall) is a bitter, greenish-yellow fluid secreted by the liver. It is stored in the gallbladder between meals and upon eating is discharged into the duodenum where it aids the process of digestion.

Too much water in the colon results in diarrhea. This occurs when insufficient fluid is absorbed by the colon. As part of the digestion process, or due to fluid intake, food is mixed with large amounts of water. Thus, digested food is essentially liquid prior to reaching the colon. The colon absorbs water, leaving the remaining material as a semisolid stool. If the colon is damaged or inflamed, however, absorption is inhibited, and watery stools result.

Increased fiber consumption appears to lower the risk of developing type II diabetes and heart disease. It may also help prevent high cholesterol and help fight obesity. High-fiber foods help move waste through the digestive tract faster and easier, so possibly harmful substances do not have as much contact with the gastrointestinal tract and reduce straining.

ATP stands for adenosine triphosphate. ATP is used for transporting energy around in your body. All the energy your body uses is supplied by ATP. ATP is made by three chemical reactions: glycolysis, the Krebs cycle, and oxidative phosphorylation.
- Glycolysis is a pathway that takes place within the cytoplasm of a cell and does not require oxygen. The reaction produces four ATP molecules, but consumes two of them during the process.
- The Krebs Cycle is a pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy. The Krebs cycle produces ATP and another chemical called NADH.
- Oxidative phosphorylation converts the leftover NADH produced by the Krebs cycle into more ATP.
While glycolysis does not require oxygen, the other two ATP-producing reactions do. We need to breathe oxygen to supply it to these processes.

Fat-soluble vitamins may be stored in the body and can cause toxicity when taken in excess. Water-soluble vitamins are not stored in the body, with the exception of Vitamin B12, which is stored in the liver.
Fat-soluble vitamins include A, D, E, and K.
Water-soluble vitamins include the eight B's and C.

Then he said to me, "Son of man, eat this scroll I am giving you and fill your stomach with it." So I ate it, and it tasted sweet as honey in my mouth.
Don't you see that whatever enters the mouth goes into the stomach then out of the body?
"Food for the stomach and the stomach for the food" - but God will destroy them both. The body is not meant for sexual immorality; but for the Lord and the Lord for the body.
From the fruit of his mouth a man's stomach is filled; with the harvest from his lips he is satisfied.
