PPT-Gas Exchange and Pulmonary Circulation

Gas Pressure Gas pressure is caused by the molecules colliding with the surface In the lungs the gas molecules are colliding with the surfaces of the respiratory passages and alveoli Higher concentrations of gas will produce more collisions and cause a higher pressure. Essentials of Exercise Physiology. Respiration. External respiration:. . ventilation and exchange of gasses in the lungs (pulmonary function).. Internal respiration. : . ventilation and exchange of gasses in the tissues (pulmonary function).. 2012. Increased Efficiency through the Study of Moving Materials .

While budgeting may not be something you are naturally inclined to do, if you are planning for something like a vacation that has the potential to rack up hundreds of dollars in expenses, it is often the most sensible option, particularly if you are not in a high earning bracket or have other daily costs and expenditures to consider. Respiration. External respiration:. . ventilation and exchange of gasses in the lungs (pulmonary function).. Internal respiration. : . ventilation and exchange of gasses in the tissues (pulmonary function).. Rajan Joshi MD,FCCP, FAASM. Assistant Professor, Pulmonary Critical care, Sleep Medicine at UKHC.

Embolism . is the occlusion or obstruction of a vessel by an abnormal mass transported from a different site by the circulation. An embolus . is a detached intravascular solid, liquid, or gaseous mass that is carried by the blood to a site distant from its point of origin. . In the fully developed human, the heart serves two main purposes. . The right heart pumps blood to the lungs for oxygenation and the left heart pumps oxygenated blood to rest of the body. . In the embryo and fetus, the lungs do not oxygenate the blood. . Which gases will leaves be exchanging?. Gas Exchange in Leaves. What features will gas exchange organs have to maximise the rate of exchange?. Large surface area, short diffusion pathway, concentration gradient. In groups. discuss what is meant by the word “exchange”. 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 outcomes. Students should be able to understand the following:. The structure of fish gills and how water is passed along them. The difference between parallel flow and . countercurrent. flow. Differences from Systemic Circulation . Low peripheral Resistance . Low pressure . Systolic20-25 mm Hg, Diastolic 6 -12 mm Hg & Mean 15mm Hg. Pulmonary Arterioles Thin walled, large lumen . Pulmonary Capillaries shorter and wider and blood flow is pulsatile .
