Webb11 sep. 2024 · Airways branch and get smaller, ending in tiny air sacs called alveoli. Alveoli are covered in small blood vessels named capillaries, which function to exchange gases in the blood [ 1 ]. The lungs can be compared to a tree that has a large, main trunk with branches becoming smaller the further away they are from the trunk. In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts. The main functions of the microcirculation are the delivery of oxygen and nutrients and the removal of carbon dioxide (CO2). It also serves to regulate blood flow and tissue perfusion thereby affecting blood pressure and responses to inflammation which can include edema (swelling).
