Name: EBME 202 Homework #3 Reference: Rhoades and Pflanzer 4 th edition, page 666 T21-2 Warning: When we ask for SHORT sentences we mean, in fact, 1 sentence. Items identified in this way can be described with one well thought out sentence. We will not give credit for long, wandering explanations except where we explicitly ask for more than 1 sentence. Advice: Read the ENTIRE assignment BEFORE taking any action. The parts are related to each other. Therefore an error in one place will lead to errors later. Because the answer to question #3 is so critical to the entire homework the TA’s and I will be happy to verify that your answer to #3 is accurate (within reasonable limits). We will NOT give you the answer if you do not get close to the correct answer, you will have to discover that on your own. We are always happy to give “hints”. The situation: A person with a total lung capacity (TLC) of 5L and a vital capacity (VC) of 5L has been breathing normally for a long time. He takes 10 VC breaths in quick succession. 1. He then starts holding his breath. a. Is a TLC of 5L reasonable for an adult male? (yes/no) b. Is a VC of 5L reasonable for an adult male? (yes/no) 2. The respiratory quotient (RQ) for this person is 0.80. RQ is defined as CO 2 production (mL/ min)/O 2 consumption(mL/min). We know that the O 2 consumption for this person is 250mL/min. At the end of 10 VC breaths, we can make a few assumptions: Alveolar air has the same composition as ambient air (including water vapor). Constant O 2 consumption, leaving the alveoli at a constant rate. CO 2 is pumped into the alveoli at a constant rate.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
