I thought more blood vessel but you are right it looks like an OGD examination. Interestingly if you do a bronchoscopy (inside the lungs) - healthy lungs also can look quite similar to this, as do most parts of the gut. I suppose the body is in many ways a collection of lots of tubes and most of them look like this.
