What else can I help you with?
What structure in villi absorbs and transports fats?
Lacteal absorbs fatty acids. Glycerol is absorbed by both , blood capillaries and lacteal .
What is inside a villi?
Inside a villi, you can find blood vessels and a lacteal, which is a lymphatic vessel responsible for absorbing fats and fat-soluble vitamins from the small intestine. The villi also contain absorptive cells that help absorb nutrients from digested food into the bloodstream.
What body system is the lacteal found?
The lacteal is found in the small intestine. It serves the purpose of absorbing fats from the gut into the bloodstream.
What does the villi absorb nutrients from the small intestine to?
Most nutrients are absorbed directly into the blood but fats are taken into the lacteal (part of the lymphatic system)
What are the tiny fingerlike projections inside the small intestine called?
The finger like projections that line the small intestine are called, Villi.
What is found inside of the intestine that helps with absorption?
the villi
What increase the free surface area of epithelium that absorb substances?
Villi and microvilli.
The small intestine is covered in millions of villi what are villi and what is their job?
Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.
What substances in the small intestine of humans serve to increase the surface area for absorption?
Villi
What cellular organelle is a projection that moves substances along the surface of a cell?
cilia
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. :)
What substances are exchange in the villi?
Nutrients, such as glucose and amino acids, are absorbed into the bloodstream through the villi. Additionally, vitamins, minerals, and water are also absorbed. Waste products, such as carbon dioxide and metabolic byproducts, are exchanged in the villi to be eliminated from the body.
