Digestive System

Some nuts, berries, and vegetables do not break down much in the digestive tract. Without proper and complete chewing (mastication), some foods pass through fairly unchanged, for example, whole corn.

Bile will bring about a chemical change to fat. This is because bile chemically alters the way the fat is structured.

Ingestion- Taking food into digestive tract via mouth

Propulsion- Moves food through the alimentary canal, includes swallowing, which is initiated voluntarily and peristalsis an involuntary process

Mechanical digestion- Physically prepares food for chemical digestion by enzymes. Includes chewing, mixing of foods with saliva by tongue, churning of food in stomach, and segmentation or rhythmic local constrictions of the intestine

I told them I would sing a page from the construction Bible if they would announce the singing of this popular hymn.

Chemical digestion- Series of catabolic steps in which complex food molecules are broken down to their chemical building blocks by enzymes secreted into the lumen of the alimentary canal

Absorption- Passage of digestion end products from the lumen of GI tract

through mucosal cells by active or passive transport into blood or lymph.

Defecation- Eliminates indigestible substances from body via anus in the form of feces.To my knowledge, THE LUMEN FROM THE tract through mucosals cells by actve or passive tansort into blood or lymph.

BILE is digested. BILE gives the color to your feces. It helps to break down fats.

the stomach is the mixer of the food , actually it has two main functions : storage of food and mixing.

Cholesterol

Lysosomes

A protein is a substance which is built up by at least 50 amino acids linked together by peptide bonds.The digestion starts by the human body producing the enzyme "Pepsin". This takes place in ourstomach.

In the duodenum the enzyme "Trypsin" will be added. This enzyme will finish the digestion of the protein.

The final product is now amino acids and peptide chains, ready for absorption.

An open digestive system is one where there is an entrance "mouth" in one end of the organism and an "exit" or anus of some sort in the other end of the organism. (think of worms or people). A closed digestive system is in something like a hydra or anemone where there is just one cavity and one opening that acts as both mouth and anus.

Peristalsis is the name of the digestive tract muscles pushing the food along... Is this what you were referring to?

peristalsis moves feces through the colon.

Most of the digestion occurs (believe it or not) not in the stomach, but the smaller intestine.

because Pepsin is only active in an acid medium and is destroyed in an alkaline and neutral medium at room temperature and below

Cellular waste is a broad term. The stuff your cells excrete are transported away by different systems. Much of the waste products and useless chemicals end up being filtered out by the kidneys and are then tossed out of the body through urinating. Carbon-dioxide, the waste gas produced by the cellular metabolism, is reabsorbed into the bloodstream and exits through the alveoli in the lungs.
