The<unk>  is a single layer of endothelial cells on the inner surface of the<unk>  It faces the chamber formed between the<unk> and the iris. The<unk>  are specialized, flattened, mitochondria-rich cells that line the posterior surface of the<unk> and face the anterior chamber of the eye. The<unk>  governs fluid and solute transport across the posterior surface of the<unk> and maintains the<unk> in the slightly dehydrated state that is required for optical transparency.
