Web28 mrt. 2024 · The alveoli are adapted to provide a very large surface area for gaseous exchange: small size - each of the alveoli is a small sphere about 300 μm in diameter, giving it a larger surface area... WebA gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. Gills are simply layers of tissue adapted specifically to gas exchange. The complexity of the gills depends on the animal’s requirement for oxygen.

Where does diffusion occur in fish? Pet Reader
WebGas exchange is important for fish as they need oxygen for respiration. Considering Fick’s law, in order to maximise the rate of gas exchange, fish have many gill filaments covered in lamellae, maximising the surface area available.In order to maximise the concentration gradient, the gills have a good blood supply to ensure that oxygenated blood is removed … Web2 jan. 2024 · Gas exchange surfaces are adapted to maintain a high rate of diffusion: they have a large surface area, are thin, and are ventilated to maintain high concentration gradients of oxygen and carbon dioxide. Ventilation happens due to changing volume and pressure (in the buccal cavity in fish). Web11 sep. 2024 · Most animals and plants consist of different types of cells organised as tissues, organs and systems.
