From Within The Alveolus Single-layered Alveolar , Located
From within the alveolus single-layered alveolar , located on to a membrane, a wall basis makes a fabric from collagenic fibres. On a layer is the membrane of a capillary and it Thus, the blood proceeding on vessels, is separated from air which is in alveoluses, very thin partition through which gas exchange is carried out. Blood circulation in lungs: the blue blood from the top and bottom hollow veins gets in right , and then through a pulmonary artery and its branches - to lungs. To each bronchial tube there corresponds a branch of a pulmonary artery which and together with bronchial tubes and eventually breaks up to the pulmonary capillaries shrouding alveoluses At this level there is an exchange of gases then the - arterial blood enriched - by oxygen arrives from capillaries in lung veins. Each lung has two pulmonary veins top and bottom which join the left auricle-, whence blood rich with oxygen arrives in left and then in the big circle of blood circulation. Walls of bronchial tubes and a lung fabric are supplied with arterial blood from bronchial arteries.
