Epithelial tissues are the smooth tissues that cover surfaces in the body. They serve as a protective barrier and are found in the skin, lining of organs, and throughout the body. Epithelial tissues are designed to absorb, secrete, and protect underlying structures.
there are actually four the Epithelial tissue includes glands and tissues that cover interior and exterior body surfaces. Connective tissue provides support for the body and connects its parts.Nervous tissue transmits nerve impulses throughout the body.And muscle tissue,along with bones,enables the body to move
Epihelial tissue coats surfaces.
Artificial joints must have very smooth surfaces to reduce friction, wear, and potential damage to surrounding tissues. A smooth surface helps minimize the production of wear debris that can lead to inflammation and complications in the body. Additionally, a smoother surface can improve the long-term durability and functionality of the artificial joint.
Smooth surfaces usually have less friction than rough surfaces because there are fewer irregularities and protrusions that can create resistance when two surfaces rub against each other. This causes objects to slide more easily on smooth surfaces compared to rough surfaces.
Yes, polyurethane can smooth out rough wood surfaces by providing a protective and smooth finish when applied correctly.
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.

True.
Smooth vs. Rough surfaces. Rough surfaces have more surface area than smooth surfaces. This means that there are increased incidences of molecular reactions between the surface and object
Yes, smooth surfaces can still produce friction. Friction is caused by the resistance between two surfaces when they are in contact with each other, not only by the texture of the surfaces. Smooth surfaces can still generate friction, although the amount of friction may be lower compared to rough surfaces.
It is wrong to say that friction doesn't occur in smooth surface.. As ideally, no such surface exists, which has 0 value of friction. We can say that the magnitude of friction force is less in smooth surfaces as compared to that in rough surfaces. Friction opposes the motion of a body. When we go to the molecular level, we can see that the surface of a plane is not smooth but rough.. We cannot see that roughness through naked eyes. But the amount of roughness differs from object to object. The so called smooth surfaces have less roughness as compared to un-smooth surfaces. Hence, the magnitude of friction is LESS in smooth surfaces...
