PATHO TEST 3 questions and answers latest update Graded A+ Alveolar pressure • When the glottis is open and there is no air movement-alveolar pressure = atmospheric pressure = 0 cm H20 • With contraction of the diaphragm, pressure in the alveoli falls (-1 cm H20) during inspiration (falls below atmospheric pressure) • With relaxation of the diaphragm, the lungs & thorax recoil and alveoli pressure increases (+1cm H20) during inspiration - rises above atmospheric pressure Pneumonia pathogenesis Aspiration pneumon
