The diagram shows the lining of the small intestine.How do villi affect the diffusion of nutrients?The folded membrane provides more surface area for particles to diffuse across and this decreases the rate of diffusion.The folded membrane provides less surface area for particles to diffuse across and this increases the rate of diffusion.The folded membrane provides more surface area for particles to diffuse across and this increases the rate of diffusion.The folded membrane provides less surface area for particles to diffuse across and this decreases the rate of diffusion.I DON'T KNOWSUBMIT ANSWER

Select the option that explains why villi are shaped the way they are.They mash up foodThey move food through the digestive tractThey allow us to taste foodThey increase the surface area of the small intestine for absorption of nutrients

Villi are small structures that contain tiny blood vessels. Villi have very thin walls. Small nutrient particles can cross the villi's thin walls and move into the blood vessels. These particles are then carried in the blood throughout the body.Which part of the digestive system has villi?The small intestine. The small intestine is where most of the nutrient particles are absorbed into the blood.The stomach. The stomach is where most of the nutrient particles are absorbed into the blood.The mouth. The mouth is where most of the nutrient particles are absorbed into the blood.Submit

Villi are finger-like protrusions of the small intestine that are responsible for absorbing nutrients into the body.Give three ways in which villi are adapted for this role.

An illustration of villi in the small intestine. The microvilli are too small to see.Question 17SavedLook carefully at the diagram above and the illustration to the left.State the three ways that the surface area of the small intestine is increased.

Which of these is not an adaptation of the villi in the small intestine?Very "small"Excellent blood supplyHighly folded to increase surface areaExtremely thin walls
