WebAlveolar number showed a curvilinear increase with age and DNA, but a linear relationship to body weight. At birth the lungs had an average of 150 million alveoli, half of the expected adult number. There was a wide normal range. The surface area was between 3 and 5 m2 at birth, one twentieth of the adult value. WebLuckily, alveolar cells have found a way to counteract surface tension by producing surfactant, which is a phospholipoprotein that reduces the surface tension, keeping the alveoli open so that we can breathe properly. … t test for two sample means calculatorWebLarge surface area - many alveoli are present in the lungs with a shape that further increases surface area.
