pulmonary respiration
ventilation (breathing) and the exchange of gases (O2 and CO2) in the lungs
cellular respiration
relates to O2 utilization and CO2 production by the tissues
key role of the pulmonary system?
maintaining blood-gas homeostasis during exercise
what is the primary purpose of respiratory system?
provide a means of gas exchange between the atmosphere and the cells of the body
ventilation
mechanical process of moving air into and out of the lungs
diffusion
random movement of molecules from high concentration to low concentration
alveolar gas exchange
movement of respiratory gases (via diffusion) between the alveolar region of the lung and the blood.
circulatory transport
the transport of respiratory gases in the blood system between the lungs and the cells of the body
systemic gas exchange
movement of respiratory gases (via diffusion) from blood into cells of the body.
bulk flow
movement of molecules along a passageway due to a pressure difference between the two ends of the passageway
Vital capacity )VC)
max amount of gas that can be expired after max inspiration
residual volume (RV)
volume of remaining gas in the lungs after max ecpiration
total lung capacity (TLC)
volume of gas in the lungs after max inspiration

engineering
A setup as in figure has the R-410a initially at $150\ \mathrm{psia}, 120\ \mathrm{~F}$ of mass $0.2\ \mathrm{lbm}$. The balancing equilibrium pressure is $60\ \mathrm{psia}$, and it is now cooled so that the volume is reduced to half of the starting volume. Find the heat transfer for the process.

Define the word personality.
engineering
Hot water $\left(c_{p h}=4188 \mathrm{J} / \mathrm{kg} \cdot \mathrm{K}\right)$ with mass flow rate of 2.5 kg/s at $100^{\circ} \mathrm{C}$ enters a thin-walled concentric tube counter-flow heat exchanger with a surface area of $23 \mathrm{m}^{2}$ and an overall heat transfer coefficient of $1000 \mathrm{W} / \mathrm{m}^{2} \cdot \mathrm{K}.$ Cold water $\left(c_{p c}=4178 \mathrm{J} / \mathrm{kg} \cdot \mathrm{K}\right)$ with mass flow rate of 5 kg/s enters the heat exchanger at $20^{\circ} \mathrm{C},$ determine (a) the heat transfer rate for the heat exchanger and (b) the outlet temperatures of the cold and hot fluids. After a period of operation, the overall heat transfer coefficient is reduced to $500 \mathrm{W} / \mathrm{m}^{2} \cdot \mathrm{K},$ determine (c) the fouling factor that caused the reduction in the overall heat transfer coefficient.
