- villus increase the surface area over which food is absorbed
- an epithelium, consisting of only on thin layer of cells, is all that foods have to pass through to be absorbed
- protrusions of the epithelium cells increase the surface area for absorption. This projections are referred to as microvilli
- protein channels in the microvilli membranes allow rapid absorption of foods by facilitated diffusion and pumps allow rapid absorption by active transport
- mitochondria in epithelium cells provide the ATP needed for active transport
- blood capillaries inside the villus are very close to the epithelium so the distance for diffusion of foods is very small
- a lacteal in the center of the villus carries away fats after absorption

∙ 14y ago1. Its presence are in a very large number to provide a large surface area for absorption of mineral salts
2. They possess thin epithelial walls
3. They have dense blood capillaries

∙ 13y agoThey are tiny microcilli which have finger-like projections that help them to adapt to the cold temperature in the intestine. They also have folds to control the surface area (small to big or vice versa).

Why villi is suited for its function?
One reason that villi are suited to their function is because they have a large surface area to absorb nutrients from food to pass through to the bloodstream.
What is the villi function?
Increase surface area for food
What is diffusion in the villi?
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
How the structure of the brain is adapted to its function?
Via and through hundreds of thousands of years of doing just that, adapting functions to suit conditions.
How the structure of the placenta is related to its function?
The structure of the placenta is directly related to its function of facilitating nutrient and gas exchange between the mother and fetus. The placenta is composed of villi, which are finger-like projections that increase the surface area for exchange. The villi are surrounded by maternal blood sinuses, allowing for the diffusion of oxygen and nutrients from the mother's blood to the fetal blood, and the removal of waste products from the fetal blood.
How is the structure of the villi adapted to their function?
The villi is only one cell thick so it easier to absorb.
How does the structure of the villi assist with the utilization of digested fish?
how does the structure of the villi
Describe two wys in which the structure of a capillary is adapted to its function?
Two ways in which the structure of a capillary is adapted to its function is to encourage the exchange of oxygen. Another reason is to encourage the exchange of carbon dioxide.
What structure enables the small intestine to absorb large amounts of nutrients?
villi
Villi are part of the structure of the?
Villi are part of the structure of the small intestine(ileum). They help increase surface area for absorption of nutrients.
Why are villi so important in the digestive process?
Villi are found in our small and large intestines, and are adapted to their function by having a very large Surface Area to volume ratio. They are vital as they extract the vital nutrients from the food we eat and are absorbed into the blood supply which runs just underneath the villi, and transport these nutrients to wherever they are needed.
How is the small intestine adapted to absorb the nutrients?
it is adapted to absorbing nutrients due to the villi present in the small intestine.
What is the function of villi cells in the intestines?
the villi vastly increases the surface area for the absoption of food.
What are tiny fingerlike projections that cover the folds of the small intestines?
Villi. Also the Villi are covered in Micro-villi - just the same but smaller. The function of them is to increase surface area for absorption.
What structure in the small intestine absorbs the nutrients?
villi
How do the finger like structures relate to the function of the small intestine?
If you mean the hairs on the cells they are villi and micro-villi
Why villi is suited for its function?
One reason that villi are suited to their function is because they have a large surface area to absorb nutrients from food to pass through to the bloodstream.
