No, villi are not completely smooth. They are finger-like projections found in the lining of the small intestine that increase the surface area for nutrient absorption. This increased surface area helps in the efficient absorption of nutrients from digested food.

What are the three types of villi?
The three types of villi are: Intestinal villi-microscopic finger like projections on the inner surface of the ileum. Chorionic villi-villi on the outermost membrane of the foetus. Arachnoid villi-villi on the arachnoid membrane of the brain.
Are finger like projections of the mucosa?
Villi. Most absorbtion occurs in the ileum btw.
What is the small finger-like bumps in the small intestine?
They are called villi.
What is the organ that has villi to absorb the nutrients?
The small intestine has villi to absorb nutrients. Villi are small projections that increase the possible surface area for absorption.
What drains cerebrospinal fluid in to venous blood in the dural sinus?
Cerebrospinal fluid is drained into venous blood in the dural sinuses through structures called arachnoid granulations (also known as arachnoid villi or pacchionian bodies). These specialized projections of the arachnoid mater penetrate through the dura mater into the superior sagittal sinus and other dural sinuses, where they allow for the reabsorption of cerebrospinal fluid into the bloodstream.
How is surface area maximized in the stomach and small intestines?
The stomach lining is quite smooth. The small intestine is lined with villi which increases surface area. Think of villi as little round popsicle sticks protruding from the lining.
What happens if the small intestine was smooth rather than covered with villi?
You would slowly starve and die, no matter how much you ate.
What structure enables the small intestine to absorb large amounts of nutrients?
villi
What are the three types of villi?

What is a easy definition for micro villi?
A micro villi is a micro villi
What would happen if there where no villi only a smooth surface?
Without villi in the small intestine, nutrient absorption would be severely compromised. Villi increase the surface area of the intestine for better nutrient absorption. Without them, nutrients would not be efficiently absorbed, leading to malnutrition and other health issues.
Are finger like projections of the mucosa?
Villi. Most absorbtion occurs in the ileum btw.
How do you make villi plural?
Villi is plural. One is Villus, many are Villi.
Why can't the wall of the small intestine be smooth?
It needs finger like protection as it is used for digestion. So it needs to be curvy.
Do mammals have villi?
Yes, mammals have villi. An example is the villi in the intestines of humans which help to absorb nutrients.
What is villi means?
"Villi " is not a word in English language.
Projection on the intestinal wall are called?
villi villi
