Eustachian tube

A narrow, slightly slanted and gently curved anatomical tube connecting the middle ear region to the upper throat, shown as a soft pale pink canal with smooth walls and a slightly flattened cylindrical shape. The tube is narrower at the ear end and widens toward the pharyngeal opening, with a subtle taper along its length.
