The respiratory system, breathing and respiration (CCEA) - BBC Bitesize
WebAlveolar pressure fluctuations are caused by expansion and contraction of the lungs resulting from tensing and relaxing of the muscles of the chest and abdomen. Each small increment of expansion transiently increases the space enclosing lung air. There is, therefore, less air per unit of volume in the lungs and pressure falls. WebRespiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake. There are 2 types of respiration - aerobic and anaerobic. maven tomcat8依赖

WebThe respiration can be aerobic, which uses glucose and oxygen, or anaerobic which uses only glucose. Respiration must happen all of the time so that the organism can survive. Releasing energy... WebJan 16, 2024 · Breathing Definition Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation. Breathing is also called ‘external respiration’ as it is an external process of taking oxygen in and throwing carbon dioxide out via respiratory organs. WebThe respiratory system transports oxygen from the air we breathe, through a system of tubes, into our lungs and then diffuses it into the bloodstream, whilst carbon dioxide makes the opposite... maven tomcat8坐标
