What serves as an emulsifying agent in the small intestine?
bile
What is the small pouch located on and and of the large intestine which serves no purpose?
Appendix
Where is the cecum is located?
The cecum is located in the first part of the large intestine. This serves as a connection between the ileum to the ascending colon and a part of the intestine that moves the waste to be excreted.
The appendix is located in the?
The appendix is a flap on the large intestine. It serves almost no purpose.
Compare absorption in the small intestine with absorption in the large intestine?
Almost 90% of our daily fluid intake is absorbed in the small intestine.The small intestine is covered with villi and microvilli. They increase the surface area of the intestinal wall exposed to chyme by 60,000%. The increased surface area makes the small intestine very efficient in absorption. Capillaries in the villi absorb amino acids, glucose, fructose, and galactose while lacteals absorb fatty acid and glycerol to travel through the lymphatic vessels.The large intestine serves as a reservoir for the liquids emptied into it, through the ileocecal valve, from the small intestine. It has a much larger diameter than the small intestine. The large intestine, or colon, may be divided into the cecum, ascending colon, transverse colon, descending colon, and sigmoid colon. The primary function of the colon is to absorb water and electrolytes (substances, such as salts, that in solution take on an electrical charge) from the ileal contents and to store fecal material until it can be evacuated by defecation.
What extra piece attached to the large intestine serves no discernible purpose and can be removed?
The appendix.
What animal had a large intestine that serves as a site for fermentation as well as absorption of water and electrolytes?
a cow
Whice what animals has a large intestine that serves as a site for fermention as well as absorption of water and electrolytes?
horse
Why does crushing a solid increase the speed at which the solid dissolves?
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.
What role do the mouth and other digestive organs play in digestion?
The mouth increases the surface area of the food so that it will be easier to be digested in the stomach/small intestine. The stomach breaks down proteins and makes the food acidic, while the small intestine breaks down fats, lipids, and proteins and makes the food return to a normal pH. The liver synthesizes bile, which serves as an emulsifier, which means that it breaks down the fat by increasing the surface area to volume ratio. Those are probably the "main ones", but there are other important ones like the large intestine.
Are the intestines linked to the nervous system?
no it is a part of the digestive sistem
Which animal has a large intestine that serves as a site for fermentation as well as absorption of water and electrolytes?
Animals that have a large intestine that serves as a site for fermentation as well as absorption of water and electrolytes are humans and horses.
