- 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
What else can I help you with?
Does the principle of complementarity of structures and function means that the structure of a part reflects its fuction?
Yes, the principle of complementarity of structures and function states that the form of a structure is related to its function. In other words, the specific features of a biological structure are adapted to perform a specific function efficiently. This principle is fundamental in understanding how the anatomy and physiology of organisms are interrelated.
Why villi is suited for its function?
Villi are suited for their function because they greatly increase the surface area of the small intestine, allowing for efficient absorption of nutrients. Their structure includes a single layer of specialized cells called enterocytes that facilitate the absorption process. Additionally, villi have a rich blood supply and lymphatic vessels to transport absorbed nutrients quickly to the rest of the body.
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.
The level of structure of an organism leading to the villi?
The level of structure of an organism that leads to the formation of villi is the tissue level. Villi are tiny, finger-like projections lining the small intestine that increase its surface area for nutrient absorption. Villi are made up of simple columnar epithelial cells supported by connective tissue.
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 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
What structure enables the small intestine to absorb large amounts of nutrients?
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.
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.
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.
Does the principle of complementarity of structures and function means that the structure of a part reflects its fuction?

In other words, the specific features of a biological structure are adapted to perform a specific function efficiently. This principle is fundamental in understanding how the anatomy and physiology of organisms are interrelated.
What is the function of villi cells in the intestines?
the villi vastly increases the surface area for the absoption of food.
Why villi is suited for its function?
Villi are suited for their function because they greatly increase the surface area of the small intestine, allowing for efficient absorption of nutrients. Their structure includes a single layer of specialized cells called enterocytes that facilitate the absorption process. Additionally, villi have a rich blood supply and lymphatic vessels to transport absorbed nutrients quickly to the rest of the body.
What structure in the small intestine absorbs the nutrients?
villi
Which structure located on the walls of the ileum form lymphocytes?
villi
What is tiny finger shaped structure in which absorption occurrs?
villi
