WebThe alveoli are the tiny air sacs in the lungs where gas exchange happens. And their walls are lined by a thin film of water, which creates a force at their surface called surface tension.. Surface tension tends to collapse the … WebWater and oxygen can move across the membrane of the alveoli in the lungs. How would their paths through the alveoli cell membrane differ? Also, in the motor neuron, substances have to move across the membrane to ensure the correct functioning of the nervous system.

http://www.dynamicscience.com.au/tester/solutions1/biology/respiratory/lungs.htm WebDiffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air. For example, think about someone opening a bottle of perfume in a room filled with people.

WebJun 16, 2024 · In the body, oxygen is used by cells of the body’s tissues and carbon dioxide is produced as a waste product. The ratio of carbon dioxide production to oxygen consumption is the respiratory quotient (RQ). RQ varies between 0.7 and 1.0. If just glucose were used to fuel the body, the RQ would equal one.

WebDec 14, 2024 · When a breath is taken during inhalation, the concentration of the incoming oxygen is higher in the alveolus than in the red blood cells.
