What adaptation does the small intestine have to help diffusion?
Wiki User
∙ 13y ago
Diffusion is needed in the small intestine so that nutrients from digested food can be diffusedinto the blood vessels of the intestine wall. The lining of this wall is called the mucosa and is covere in tiny wrinkles that form indents in the surface. Not only does this increase surafce area but there are tiny hairs called villi as well that add even more surface area. The villi are also covere in microvilli. Rhis means more surface for nutrient absorption. Furthurmore these villi are only one cell thick meaning substances cam easily be exchanged to and from the blood vessels.

How does folding the small intestine help to speed up absorption?
Increased surface area allowing for greater nutrient absorption.
How do microvilli help with absorption?
The microvilli have finger-like shapes originating from the villi that line the small intestine. They greatly increase the surface area of individual cells when it comes to absorbing nutrients.
What are villi and what role do they play in the process of absorption?
Villi are finger-like projections in the small intestine. Their role is to help the body absorb nutrients from the food. The villi are little tiny hairs inside the small intestine that absorb nutrients.
What organs produce enzymes that help in digestion?
The small intestine produces digestive enzymes. Certain things that you eat are digested in different parts of the body by different systems.
How does the small intestine and the stomach work together?
the stomach churns the food making it into smaller particles. also there are enzymes in the stomach that break up protiens and can only survive in stomach acid. they do this so that the food will not burn the small intestine. Bile is released from the liver into the stomach that help to break up fats. as the food passes through the small intestine its nutrients are absorbed by the villi and are taken into the blood stream.
What 2 features of a villi help the small intestine function?
Large surface area Thin- Short distance for diffusion
How does the structure of the small intestine help the Small intestine?
the villi in the small intestines.
What does the small intestine help in?
The small intestine is where your food goes after the stomach. The small intestine digests your food, then sends it to the large intestine.
Is the small intestine is narrower than the large intestine?
yes it is! but the large intestine is shorter then the small intestine...Did that help? Hope I did! :)
What are the three glands that help to complete the digestions?
the three glands that help to complete the digestion are large, intestine small intestine and kidney
Why are the intestines so good at absorbing food molecules?
The small intestine has many villi, small projections into the lumen of the small intestine. These villi increase the surface area of the small intestine, and increase the funcitonal area for the absorbtion of nutrients.
Organ that receives pancreatic juice and bile?
The duodenum (the first part of the small intestine).
Which part of the small intestine receives bile from the gallbladder and liver?
The first part of the small intestine, or duodenum, is where the small intestine receives bile to help digest fats.
What are the organs that help in the digestion?
They are the large and small intestine
How can the small intestine help the digestive system?
it doesn't
How are nutrients absorbed by the intestine cells?
it depends on the nutrients and their size. some nutrients absorb via diffusion, others is facilitated diffusion (needs a carrier protein and no energy), and others are via active transport (needs energy and a protein channel).
What does the small intestine do in a ruminant digestive system?
In the small intestine, carbohydrates, fats and proteins are being emulsified with the help of some digestive enzymes.
