Physioex 8 Exercise 7

happened to the left lung when you clicked on the valve button? It deflated. 2. Why? Because the pressure in the left lung was 0 and the right lung changed rapidly, the air moved into the intrapleural space through the opening, causing intrapleural pressure. 3. What has happened to the “Total Flow” rate? It was reduced by ½. 4. What is the pressure in the left lung? 0 5. Has the pressure in the right lung been affected? It remained the same. 6. If there was nothing separating the left lung...

Physioex 8 Exercise 1

increases the osmotic pressure will increase. 6. Does diffusion allow osmotic pressure to be generated? No 7. Would pressure be generated if solute concentrations were equal on both sides of the membrane? No it does not generate 8. Why or why not? They are isotonic, they do not contribute to the tonicity of a solution as they pass through 9. Would pressure be generated if you had 9 mM glucose on one side of a 200 MWCO membrane and 9 mM NaCl on the other side? If so, which...
