Lamellae are thin, plate-like structures found within fish gills that increase the surface area available for gas exchange. They contain numerous capillaries, allowing for efficient oxygen absorption from water and the release of carbon dioxide. The close proximity of blood vessels to the water flow enhances the diffusion process, ensuring that fish can efficiently extract oxygen even in oxygen-poor environments. This specialized structure is crucial for the respiratory efficiency of fish.

The origin of lamella is from the Latin language. In Architecture it is a piece of metal, lumber or concrete that crosses to keep a roof structure in place. In anatomy it is a fragile layer of calcium that assists the formation of bones.
Lamellae are thin layers of tissue surrounding structures such as gills in fungi, fish, or other organisms. They provide a large surface area for functions like gas exchange, nutrient absorption, or filtration.
Gas exchange is a function of respiration not digestion.

The organ in both fish and clams that serves a similar function to the papulae of starfish is the gills. Gills are responsible for gas exchange, allowing aquatic animals to absorb oxygen from the water and expel carbon dioxide. In starfish, papulae also facilitate gas exchange and help in excretion, functioning similarly to gills in terms of respiratory processes.
