Explanation:

Anastomoses are more common in veins than in arteries. Often, an artery travels with a corresponding vein. These vessels are called companion vessels because they supply the same body region and tend to lie next to one another. Both artery and vein walls have three layers, called tunics.

the ileocecal valve (also called bauhin valve), which limits the rate of food passage into the cecum and may prevent material from returning to the small intestine.
