How is digestion a chemical change?
Food digestion is a chemical change. Chemical reactions catalyzed by enzymes break down the food ingested into its component particles and these particles cannot be put back together through mechanical means.
Summarize the life cycle of Ascaris?
Ascaris start out as eggs born in the small intestine and are passed through the feces. After they are ingested, the eggs hatch into larvae and grow in the intestine before moving into the lungs. They then move up the throat to be swallowed and live and reproduce in the small intestine again.
What organs are involved in the human digestive system?
The most important are the stomach, small intestine, pancreas, and large intestine. Most of your food is digested by the small intestine in its first section called the duodenum. And the large intestine reabsorbs water and eliminates the undigested food in the feces.
Where does fats start changing to fatty acids and glycerol?
The process of fats changing into fatty acids and glycerol begins in the small intestine. When fats are ingested, they are broken down by enzymes called lipases in the small intestine, resulting in the release of fatty acids and glycerol, which can then be absorbed into the bloodstream.
Compared to the ingested food molecules the end product molecules of digestion are usually?
Smaller and simpler molecules that can be absorbed by the body, such as glucose, amino acids, and fatty acids.
What is are produced as a result of the mechanical digestion of a piece of meat?
After a persons stomach was surgically removed the chemical digestion of ingested protein would probably begin in the
What is the definition of digestion in man?
Digestion is the process by which ingested (eaten) food is broken down (by acid and enzymes) and absorbed (into the blood, through the lining of the small intestine).
What are the three sections of the small intestine and what role does each section play in digestion or absorption?
The 3 parts of the small intestine are: the Duodenum, the Jejunum, and the Ileum.The small intestine is the site where most of the nutrients from ingested food are absorbed. The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue.
What is the small intestine funchion?
As far as the main function of small intestine is concerned, it is the part where the 'most extensive part of digestion' occurs. The large intestine is most responsible for absorption of water and excretion of solid wastes, thus, works more towards dealing with the bulk and its removal from the body. Since, the large intestine deals with bulk, it is shorter and wider, while the small intestine's narrow width corresponds to the absorption and digestion process carried out. Food ingested via the mouth enters the stomach and is allowed to enter the duodenum by a muscle called pyloric sphincter. The ingested food is then pushed through the small intestine by a muscular-wavelike process called peristalsis.
What are part of small intestine and large intestine?
The Small and Large Intestines are part of the Digestive System. The Digestive System is responsible for allowing an organism to transform ingested food into chemical energy for that organisms survival.
How does fat leave a person's body?
Although fat is ingested through foods it is not secreted out of the body like any other ingested thing. It gets stored in the body and it is a useful energy storage. When need the body taps into its fat storage for some excess energy. It must be burned off by exercising or taken out surgically.
Where do nutrients enter the body's circulatory system?
food ingested is broken down into smaller pieces via mechanical and chemical digestion. this takes place in the mouth stomach and the intestine. it is then absorbed (taken in) by cells of the gut called enterocytes. these cells then transfer the nutrients into the capillaries supplying the gut. in this way nutrients from your diet enter the circulatory system to transfer them to other tissues
How is the muscular system involved in digestion?
When food is ingested in the mouth, it is propelled towards the stomach then to intestines and to the anus by peristaltic movement of the muscles. Without muscles, digestion will take couple of days to occur. Food is propelled slowly through small and big intestine as most of the absorption of food occurs here.
Materials that are not digestied move into...?
Materials that are not ingested move into the colon or large intestine.
What happens when a large dog ingest cholrine?
This chemical can kill if ingested. Advise you take the dog to a vet if it has ingested a large amount of this chemical.
How is digestion a chemical change?
Food digestion is a chemical change. Chemical reactions catalyzed by enzymes break down the food ingested into its component particles and these particles cannot be put back together through mechanical means.
What does digestion do in general terms?
Digestion Brakes down ingested products into usable materials in the stomach, extracts them in the intestines, and the waste goes You-Know-Where
