What are villi functions in digestion process?
you villi is in your small intestines.
What do the capillaries of the intestinal submucosa lead directly to?
Many arterioles that penetrate the Submucosa give rise to capillary networks that supply the Intestinal Glands and villi with blood.
What are the specialized lymph capillary structures located in the wall of the small intestine?
Villi
Passage of materials through villi into the blood?
passage of materials through villi intothe blood
What is a villi job?
Villi absorb food into the blood from inside the intestines
How does the composition of blood changes as it flows through the villi?

What drains cerebrospinal fluid in to venous blood in the dural sinus?

What are villi microvilli and lacteals?
In the ileum, (3rd part of small intestine after the 1st, duodenum, then the 2nd, jejunum) is where the villi and microvilli are. The villi are folds of the illeum wall, and their purpose is to increase the surface area. They are finger-like projections. These folds, or finger-like projections, have further projections on their surface. So in other words the villi have villi on them. But they are called microvilli. They are also to further increase surface area. The villi and microvilli are there for absorption. This is where most of the absorption of the nutrients from digestion occur(a fraction in the stomach wall).These nutrients are absorbed by diffusion into a capillary in the villi. Except for the fatty acids, which are absorbed by the lacteal in the villi. The villi are very thin. This allows diffusion to occur easier as it is close to the surface. The capillary and lacteal are close to the surface for the same reason. The villi are also semi-permeable, allowing only certain molecules to diffuse, and not diffuse the other way round. The nutrients, absorbed by the capillary in the villi, are now in the blood stream where they can be used as energy and proteins are sent to the liver to be broken down into amino acids to be arranged into the protein again that the body wants. Eventually some nutrients become part of your tissue (assimilation)I hope this somewhat helps. :)but hey, im 16, what do I know. you may want to check I'm right. :)
