Where are the gill filaments located in the respiratory system? The arches are the structural component of the gill, rakers prevent debris from entering the fish through the gills, and the filaments absorb oxygen. Gills are internal organs that are located inside the operculum, which is a bony structure that covers and protects the gills in most species of fish. Each lamella comprises vertical rows of filaments upon the outer head of which are complex arrays of cilia that create a flow of water through the gill, form a filtration barrier, and transport retained particles to food grooves in the dorsal. These filaments are fine-like threads, and each contains one blood vessel. They are surrounded by blood vessels. Careers.

Most gills are made up of arches, filaments, and rakers. The gills also regulate levels of mineral ions and the pH of the blood, as well as being the primary site of nitrogenous waste excretion, in the form of ammonia. Many amphibians have external gills at some stage in their life. Fish gills are adapted for aquatic respiration, meaning they can extract oxygen dissolved in water and eliminate carbon dioxide from the body. The gills are also involved in maintaining the balance of electrolytes, such as sodium and potassium, in the body. As a member, you'll also get unlimited access to over 88,000 The secondary gill lamellae are small lamellae that come out of the primary ones and are used to further increase the contact area. A Lamella (plural: lamellae) is a soft, thin plate that is attached to the bony gill arches in a fishs gills. Bookshelf Sedentary fish that live on the bottom usually have gill filaments that absorb smaller volumes, since they are less active and don't use the oxygen as quickly.
