http://www.passmyexams.co.uk/GCSE/biology/gas-exchange.html NettetGas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange ...

NettetOne set is on the thorax and the rest along the abdomen. These spiracles allow gas exchange, taking in air to a set of long tubes that run down the body called the trachea. … NettetDuring gas exchange, oxygen diffuses from the alveoli, across the alveolar membrane and capillary wall, into the bloodstream, to be picked up by the RBCs. Carbon dioxide diffuses from the blood into the alveoli. This causes the partial pressure of oxygen in the alveoli to dwindle and the partial pressure of carbon dioxide in the alveoli to ...

The processes of inspiration (breathing in) and expiration (breathing out) are vital for providing oxygen to tissues and removing carbon dioxide from the body. Inspiration occurs via active contraction of muscles – such as the diaphragm – whereas expiration tends to be passive, unless it is forced.

NettetGas exchange allows the organisms to replenish the oxygen and eliminate the carbon dioxide. In the case of plants during photosynthesis, it allows release of oxygen and replenishment of carbon dioxide (plants also need oxygen, just like animals, for respiration). Oxygen is used to release energy as ATP during respiration.
