How fish are adapted for gas exchange
WebDescribe and explain how fish are adapted for gas exchange. Fish gills are made up of thin plates called gill filaments, which are covered in structures called lamallae. Both the gill filaments and lamellae provide a large surface area for gaseous exchange, … 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. More complex or more active aquatic organisms are possessed …

Ventilation happens due to changing volume and pressure (in the buccal cavity in fish).
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 … Webof fish. The disease causes the lamellae to become thicker and to fuse together. AGD reduces the efficiency of gas exchange in fish. Give two reasons why. 1. _____ _____ 2. _____ _____ (2) (c)€€€€ The table below shows some features of gas exchange of a fish at rest. € Volume of oxygen absorbed by the gills from each dm. 3. of water ...
WebExplain two ways in which the structure of fish gills is adapted for efficient gas exchange (2) A Many lamellae = large S.A. - Thin surface = short D.P. 6 Q In humans, substances move out of the capillaries to form tissue fluid. Describe how this tissue fluid is returned to the circulatory system (3) A hydrostatic pressure is lower in capillaries Web24 dec. 2011 · Primarily fish has gills while amphibians, reptiles, birds, and mammals have lungs for respiration or gas exchange. It would primarily comply that aquatic animals have gills and terrestrial animals have lungs, but the aquatic mammals and some of the fish species have lungs.
