What is the main difference between causing diffusion of gases to dilate or constrict or do both? What mechanisms cause the lungs to expand and recoil? Which of the following structures delivers the oxygen to the lung tissue in the pulmonary lobule? a. pulmonary capillaries b. pulmonary venules...
What causes the lungs to harden? Pulmonary fibrosisis a lung disease that occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it more difficult for your lungs to work properly. How do you know if you have lung problems? How would I know if I have a lu...

(which is a dome shaped muscle in your abdomen), contracts and pulls down making room for the lungs to expand within the chest cavity. The expansion of the lungs creates a vacuum within them, allowing air to be drawn in. As the lungs fill with air, stretch receptors tell the brain ...
2)Our lungs are normally very elastic, this allows them to expand and contract as we breath in and out. Fibrous tissue is not elastic, therefore pulmonary fibrosis causes lungs to become ‘stiff’. This is why pulmonary fibrosis is known as arestrictive lung disease. ...
