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 else can I help you with?
Most intestinal absorption occurs in the?
small intestine, and water absorption occurs in the colon/large intestine
How is small intestine better adapted for absorption than thatof large intestine?
The small intestine has small tiny projections called "villi". These projections increase the surface area for absorption. The large intestine however lacks these structures.
Diff bet large and small intestine?
The large intestine is wider in diameter and shorter in length compared to the small intestine. The large intestine absorbs water and electrolytes from the remaining indigestible food matter, while the small intestine is responsible for the majority of nutrient absorption from food. The small intestine has three sections (duodenum, jejunum, ileum) compared to the large intestine's four sections (cecum, colon, rectum, anal canal).
What does the small intestine connect from and to?
The small intestine connects the stomach and the large intestine. It is the site of completion of digestion and most absorption.
Describe digestion and absorption of food in small intestine large intestine enzymes?
Colon
Where does maximum absorption takes place in a vertebrate alimentary canal?
the large intestine
The small intestine leads to the?
The small intestine leads to the large intestine in the digestive system. After the small intestine completes the absorption of nutrients, waste products continue on to the large intestine for further processing and eventual elimination from the body.
How do small and large intestine compare in size and shape of a frog?
Amazingly the small intestine is longer! -Annabeth
Primary site for absorption of nutrients?
The Duodenum and Illeum (both parts of the small intestine) through chemical digestion
What nephron structures are involved with absorption?
The small and large intestines. The small intestine contains blood capillaries and lymph vessels.
What is the organ responsible for food and water absorption?
The small intestine is where most nutrients are absorbed, but the large intestine is responsible for most water absorption
The major site of nutrient absorption in the body is the?
The major site of nutrient absorption is the small intestine.
