Chronic obstructive pulmonary disorder is seen to be a lot more common in older adults and contribute to a lot of problems as people get older and enter into later life. Maintaining the concentration gradient is usually not an issue unless there is obstruction of the airways (among other possible diseases and malfunctions). This knowledge is very important when you are learning about disease processes such as COPD , Pneumonia, and other respiratory disorders. Purchase Respiratory Care Anatomy and Physiology - 4th Edition. We breathe in air rich in oxygen by the process called inspiration and breathe out air rich in CO2 by a process called expiration..

The orangisation sets out Englands 7 priorities which one being to reduce the amount of people smoking and to stop children starting. Divided further there are small passages called the bronchioles at the end of these bronchioles there are small air sacs which are called alveoli. We maintain this concentration gradient through breathing. This article discusses the epidemiology of COPD, reviews normal pulmonary anatomy and physiology, and explains the physiological changes to the pulmonary system caused by COPD. Since concentration gradients exist with both O2 and CO2 gas, passive diffusion is possible between the alveoli and the capillaries. obstructive = COPD obstruct the outflow by smaller diameter of bronchioles and lung trapping/turbulence--> thus to minimize WOB they want take slow, long deep breaths to minimize WOB In addition to Boyle’s law, several other gas laws help to describe the behavior of gases.

Attached to the alveoli are the tiny blood vessels called the capillaries The oxygen in which we breathe in is passed through the trachea down into the bronchus and bronchioles until it passes through the wall of the alveoli to reach the capillaries in order for gas exchange to happen. Alveolar O2 gas must be kept at a higher concentration than in the capillaries and alveolar CO2 gas must be kept at a lower concentration, so that O2 gas can diffuse into the capillary beds and CO2 gas can diffuse out of the capillary beds into the alveoli. On the most basic level, the body has evolved to contain two lungs and the trachea, a structure in the body that allows for the intake of oxygen gas and expulsion of carbon dioxide. The airways The airways branch a total of 23 times, creating a tree-like structure that ends in the alveoli, where the exchange of oxygen (O2) and carbon… This causes the rib cage and sternum to elevate, which lowers the air pressure in the lungs.
