Esophagus

Isolated anatomical view of the esophagus as a long, vertically oriented, soft muscular hollow tube in pale pink to pinkish-tan or muted pink-beige. The tube is cylindrical but slightly flattened front-to-back when empty, with slight natural curvature or waviness and a smooth outer surface showing faint longitudinal muscular texture or gentle folds. It has moderately thick walls, no cartilaginous rings, and a narrow lumen that is often collapsed or subtly folded, emphasizing its flexible, collapsible nature. The caliber is mostly uniform with possible gentle tapering toward the lower end or a slightly thicker upper end, and it appears softer and less rigid than the trachea, as the continuation of the pharynx into the digestive tract posterior to the airway. Simple anatomical illustration or clipart style.
