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.
What is the inner wall of the villi line?
The small intestine is lined with microscopic fingerlike strutcures called villi which increase the surface area of the small intestine fo absorption. The spaces between villi are like a sieve that absorb the food particles into the bloodstream. There are three types of villi. Intestinal Villi which lines the intestines, Chorionic Villi which is on the outer most membrane of a fetus and Arachnoid Villi which is on the arachnoid membrane of the brain.
Are finger like projections of the mucosa?
Villi. Most absorbtion occurs in the ileum btw.
What drains cerebrospinal fluid in to venous blood in the dural sinus?
The Cerebrospinal Fluid is absorbed into the venous blood in the dural sinuses through the arachnoid villi. Arachnoid villi connect the subarachnoid space to the superior sagittal sinus.
In which part villi is present?
villi are present in small intestine

What are the structural modifications of the small intestine to increase surface area?
villi, microvilli, and plicae circulares/circularbfolds
Which part of the digestive system contains structural adaptations called villi that increase the surface area for the absorption of nutrients?
No
Would having fewer villi in you small intestine make you underweight or overweight?
they would be underweight because they would have fewer villi and it is FEWER than normal
What are the four major components of the?
Secretive layer= mucus glands Absorptive layer= villi (mucosa, lymphatics) Mechanopropulsive layer= muscle structural layer= serosa
Would a person be overweight or underweight if they had small intestine that has fewer villi then normal?
he would be fine! :D
If an animal didn't have villi how would it overcome this problem?
It would not. Villi, like all living features, were put in place to overcome a problematical situation. Remove a solution without otherwise dealing with the problem is a dead-end.
What 2 features of a villi help the small intestine function?
Large surface area Thin- Short distance for diffusion
What are the four major components of intestines?
Secretive layer= mucus glands Absorptive layer= villi (mucosa, lymphatics) Mechanopropulsive layer= muscle structural layer= serosa
What structure enables the small intestine to absorb large amounts of nutrients?
villi
What is a easy definition for micro villi?
A micro villi is a micro villi
What structure helps increase the surface area available for absorption?
The intestinal wall has invaginations (or dips) that have a much larger surface ares compared to a simple tube
