Art style: Cinematic Realistic.
A clean anatomical diagram slide of the human oesophagus rendered as a vertical tube connecting throat to stomach, with two ring-shaped sphincter valves clearly highlighted, one glowing at the top near the throat, one at the bottom near the stomach. Centred vertical composition, eye-level flat framing with subtle labels. Soft even clinical lighting with a gentle glow on the two valves. Educational, precise mood. Palette of deep navy background, soft pink anatomical tones, and accent teal highlights.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
