yes
Lining of your intestine is not smooth. Nature has adapted various methods to increase the surface area of the intestine. The surface has become grossly uneven due to this factor. The surface area of the small intestine is about 2750 square feet. That is why the surface becomes rough, although the lining is made of very soft epithelium.
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.

smooth muscle pushes food through the intestine and smooth muscle is a involuntary muscle
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.
Smooth surface
Stomach, Intestine, urinary bladder
This is smooth muscle. It produces a wave of movement.
No actually i am a Doctor at the Doctor Associations of Australia and i deal with organs, it is more of a balloon with a smooth texture. Compared to a large intestine. If you want more from me you can check out my blog page on WWW.blogster4doctors.com You can find me on Dr Harry Wilkinson. you can find me talking about the subject "The center of your body with the submarine"
No it does not have to be smooth.
The rough surface is better than the smooth surface for the frictional force to act.
Here we are talking about the surface of the muscles..... Smooth muscles have smooth surface while striated muscles have rough surface.....
