Do Now activity Identify some of the organs involved in the gas exchange system in the human body Discuss with your partner what function of some of these organs might be within this system Explain why organisms need an efficient gasexchange system. Composition of the atmosphere. Gas solubility. Gas Exchange Fluxes. Effect of wind. Global CO. 2. fluxes by gas exchange. Emerson and Hedges: Chpts 3 and 10. Sarmiento and Gruber (2002) Sinks for Anthropogenic Carbon. Key words needed in you paragraph:. Carbon dioxide. Stomata. Closed in hot sunny conditions. Water loss. Photosynthesis (slow down). Guard cells. Diffusion . Open = turgid = bulges. Closed = flaccid = collapse. exchange by diffusion between air in the . lungs and blood in capillaries.. What can you tell me about alveoli?. Alveoli. The tiny air sacs at the end of each bronchiole are specially designed for gas exchange. . Oxygen is needed for _______________. Oxygen is needed for . cellular respiration.. What is the difference between breathing and gaseous exchange? . Discuss with a peer. 1 and . half minutes. After respiration the oxygen gas .  Apnea: cessation of breathing . . Dyspnea. : Difficulty breathing. . Bradypnea. : abnormally decreased rate of breathing. . Hyperpnea. /. Tachypnea. : abnormally increased rate of breathing . Composition of the atmosphere. Gas solubility. Gas Exchange Fluxes. Effect of wind. Global CO. 2. fluxes by gas exchange. Emerson and Hedges: Chpts 3 and 10. Sarmiento and Gruber (2002) Sinks for Anthropogenic Carbon. Key concepts. Because insufflation avoids any direct patient contact, there is no rebreathing of exhaled gases. Ventilation cannot be controlled and the inspired gas contains unpredictable amounts of entrained atmospheric air.. Chapter 22 content not on Wednesday lecture test. Goals:. -Describe the airway divisions that lead air to the alveoli where most gas exchange actually occurs.. -Describe the structure and anatomy of the lower airway anatomy as it applies to health and disease.

Apply the word exchange to a biological concept. Exchange takes place over surfaces. Write down features of a good exchange surface. Which processes are used in the exchange of substances. Learning objectives:. Must say what the job of the lungs is and name the main parts. Should describe the special features the lungs have to do their job really well. Could explain how the alveoli work. An Example . . MTZ Conference – Engine. 7. th. and 8. th. November 2007 Stuttgart. Gas Exchange in a . Combustion Engine. Accurate determination of important. gas exchange parameters directly at the test bed based on existing measured values. Breathing(External respiration) . The . process of exchange of O2 from the atmosphere with CO2 produced by the cells.. Respiratory Organs . • Direct respiration by diffusion from the environment – sponges, coelenterates, flat worms etc..
