WebDiffusion. Diffusion is when particles spread from an area of high concentration to an area of low concentration. The molecules would move randomly, and they would eventually become evenly distributed. The particles move down the “concentration gradient” and this process takes no energy (it’s a “passive” process”). WebRespiration refers to a process in which the energy is released from the glucose so that the life processes can continue. There are two types of respiration: Aerobic respiration: It …

WebRespiration refers to a process in which the energy is released from the glucose so that the life processes can continue. There are two types of respiration: Aerobic respiration: It needs oxygen. Anaerobic respiration: It does not need oxygen. Our respiratory system is adapted to carry the exchange of gases efficiently. Web5 de set. de 2012 · See answer (1) Best Answer. Copy. -The alveoli give the lungs a large surface area for absorbing oxygen and excreting carbon dioxide. -Alveoli have thin walls so that gasses diffuse easily across ...
WebThe alveolar membrane is the gas exchange surface. Gas exchange in the lung. When you inhale oxygen, it enters the lungs and travels to the alveoli. Cells lining alveoli and capillaries carrying blood are in close contact with each other. The barrier thickness averages to 1 micron - that’s 1/10 000 of a centimetre!
