Simply to increasing the efficiency of digestion and absorption.
The larger the surface area, the more space it has to absorb nutrients from the food you eat.
For absorption of nutrients
small intestine
Parasympathetic stimulation is a process that takes place in the peripheral nervous system. This is a process where signals are carried throughout the body.
Cells that line the small intestine are covered with microvilli for increased absorption.
surface area
In small intestine. You have very large surface area of the intestine is there for the same.
villi
microvilli
Villi
The wrinkles of the small intestine increase its surface area. Increased surface area gives more opportunities for absorption of nutrients, which is one of the main functions of the small intestine.
Villi
A frog's digestive surface is increased most specifically in the small intestine. This portion of the system has many folds on the inner surface, helping to increase absorption of food.
The cells that line small intestines have small projections on their surface called villi. These projections collectively increase the total surface area of the small intestine. This adaptation facilitates increased absorption of nutrients
Small intestine
Vili are present to increase the surface area of the small intestine. This allows more digestion to happen in the small intestine.
The answer is small intestine.
The large surface area of the small intestine is achieved by a combination of anatomical features such as the plicae circularis, the vili, and the microvilli.
