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.

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

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

What structures are used to absorb and conduct nutrients to the blood and lymph vessels in the villi? A. Cilia B. Microvilli C. Goblet cells D. Lumen

Both the respiratory system and the digestive system involve the uptake of necessary molecules from an animal’s surroundings. Alveoli are tiny sacs that aid in the exchange of carbon dioxide and oxygen in the lungs. Intestinal villi are tiny projections along the lining of the intestines used to take in nutrients from food passing through.Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?Ask Studybuddy (Login to use)Group of answer choicesIntegumentaryEndocrineImmuneCirculatory
