These organs consist of hemibranchs, which are combined to form holobranchs.
These organs consist of hemibranchs, which are combined to form holobranchs. In mollusks, they are known as ctenidia, and in more complex animals they are protected by the operculum. In addition to their main function, they are also important in osmoregulation and maintaining an acid-base balance. They use a countercurrent exchange system, causing blood to become almost completely saturated while water loses as much as eighty percent of its oxygen. Name these counterparts of lungs found in fish.
