EXPH 386 Exam 5 (pulmonary) Questions and Answers T OR F The lung is the only organ (other than the heart) to receive the entire cardiac output - ANS ️️ true Functions of the lung: - ANS ️️ -gas exchange -filtering (blood and air) -captures inhaled particles -breakdown vasoactive substances (metabolic functions) -converts angiotensin I to angiotensin II (related to blood pressure and kidneys) (ACE in the lungs) -bradykinin -serotonin -norepinephrine -PGE2 and PGF2 alpha -le...

Barotitis media correct answer: -typically occurs in decent -pain in the middle ear Barobariatrauma correct answer: -caused by large/sudden release of nitrogen from tissues. -pre-oxygenate prior to flight to blow off excess N2 Barosinusitis correct answer: -trapped air in the sinuses -occurs during ascent falling atmoshperic pressure canot keep the air in the sinuses compressed, causing the air to expand and place pressure on the sinus walls hypoxic hypoxia correct answer: -inad...

flux Number of molecules through an area per time, rate of passive flow of "substances" down gradients fluid/bulk flow all the molecules (ex: air) Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:01 / 0:15 Full screen diffusion movement of one type of molecule (ex: O2) what on a graph tells us the flux slope driving force for flux the difference of molecules in versus out (out-in) process of inhalin...

Define Pharmacokinetics - Answer-How does the drug concentration change as it moves through the body (entering and leaving the body) Define Pharmacodynamics - Answer-How does the drug exert its effects (power) over the body (drug receptor interactions, potency) Where does the drug concentration determine the clinical effect - Answer-In the biophase (not plasma) Absorption rate depends on what - Answer-Route of administration Distribution route - Answer-Vascular to extravascular (fat,...

IA Med/ACE Flight Physiology Exam Practice Questions and Answers What are relative contraindications for taking patients in flight? - Answer-Anemia (low Hgb) and 24+ week gestation pregnancy. The rise in altitude can trigger baroreceptors and induce early labor What is AGL in flight physiology? - Answer-Above ground level. (Aircraft to ground level) What is MSL in flight physiology? - Answer-Mean Sea Level (how far from the plane to the mean sea level) What is ASL in flight physiology? -...

AQA A LEVDefine diffusion. The net movement of molecules or ions from an area of higher concentration to an area of lower concentration until evenly distributed.Define osmosis.The movement of water from a region of higher water potential to a region of lower water potential across a partially permeable membrane. Define active transport. The movement of molecules from an area of lower concentration to an area of higher concentration using ATP and carrier proteins. State factors which ...
