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.
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 is the function of the tiny folds within the small intestines?
Inner folds are called villi and they increase the surface area and increase the efficiency of digestion and absorption by increasing the contact of intestinal secretions and food particles and also food particles and the inner surface lining of intestine.
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
What forms the Large surface area of the small intestine?
The villi on the inner surface.
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 does Chorionic villi become?
Chorionic villi are of fetal origin and eventually form the placenta

What is a lining if the small intestine?
the lining of the small intestine has folds, and are covered with finger-like projections called villi, which are covered with thousands of micro-villi
What structures form the placenta?
Chorionic villi & Decidua Basalis
What structures ultimately forms the placenta?
Chorionic villi & Decidua Basalis
What two tissues does placenta form?
trophoblasts/chorionic villi and the uterus form the placenta
What is the reason for the Villi?
The villi increases the surface area for the small intestine.
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.
Are finger like projections of the mucosa?
Villi. Most absorbtion occurs in the ileum btw.
What does the small intestine have to further increase its surface area?
The intestinal wall is covered with microscopic protrusions called villi and microvilli. These villi look like millions of tiny fingers or hairs sticking out from the intestinal wall. The villi increase the surface area of the wall because there is now much more membrane per square inch of intestine.
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.
