The word "Alvei" is spelled using the International Phonetic Alphabet as /ælˈveɪ/. The first two letters, "al," are pronounced with the short "a" sound followed by the sound of the letter "l."

Alvei refers to the plural form of the noun "alveus," which is derived from the Latin word "alvus" meaning "belly" or "hollow." In the realm of anatomy, alvei specifically represent small, hollow, and sac-like structures found in various parts of the body. These structures are often defined by their distinct shape, resembling a small cavity or indentation.
One prominent example of alvei can be observed in the lungs, where alvei are tiny air sacs or spaces located at the terminal ends of the bronchioles. The alvei in the lungs are responsible for the exchange of oxygen and carbon dioxide during the process of breathing. They facilitate the transfer of oxygen from inhaled air into the bloodstream while concurrently expelling carbon dioxide.
In the context of dentistry, alvei can also be seen in relation to the alveolar process, which is a specialized part of the jawbone. The alvei in the alveolar process serve as the sockets that anchor the roots of teeth, assisting in their support and stability.
Furthermore, alvei can be found in other anatomical features, including the intestinal mucosa, where they are responsible for the absorption and secretion of various substances, and in the kidney, where they form part of the structure responsible for urine production.
Overall, alvei are integral anatomical elements that help maintain and perform vital functions in the human body.
