Gas Exchange
Gas exchange is the process in which gases enter and leave a body by diffusion across gas exchange surfaces. Gas exchange is important as it transfers oxygen from surroundings of an organism to individual cells in the organism’s body, needed by the cells for respiration to occur. Carbon dioxide is released. This process produces energy which is essential to an organism for survival.
Group 1 – Insects
The definition of an insect is any of a group of small and often winged animals that have six jointed legs and a body formed of a head, thorax, and abdomen.
Insects use the Tracheal system for gas exchange.
The spiracles are openings of small tubes running along the inside of the insect 's body. The larger tubes branching off the …show more content…
Each gill arch is lined with filaments which are always submerged in water so they are always kept moist. Gill filaments are able to increase the surface area so that gasses between the water and the blood can diffuse easier. The gill filaments are covered in a large number of tiny folds known as lamella which further increase the surface area available for gas exchange. These filaments have many functions including the transfer of ions and water. Each filament provides a large surface area for exchanging oxygen and carbon dioxide. This makes it easier by allowing more particles to be able to diffuse at any …show more content…
They exhale the waste carbon dioxide and then fill their lungs with fresh air before diving back down beneath the surface. Whales’ lungs have a very large surface area so they can exchange gases at a quick rate. This large surface area in their lungs comes from many small alveolar sacs. Since lungs act a little like balloons they prevent the whales from diving to a certain depth within the water. The lungs in a whale are small in comparison to its body mass. There is nitrogen present in the body tissues of a whale and they need to remain dissolved so that it does not become converted back into a gas and affect the whale physically. So the whale has adapted to have a flexible ribcage so it can maintain optimal pressure by collapsing under the heavy weight of the water as the whale dives deeper and deeper beneath into the ocean. With little air left in the lungs, nitrogen cannot dissolve into the body tissues. The then lungs collapse, being almost emptied of the gaseous
