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...

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,...
