 * = **Lungs** || Main function is gas exchange; R lung has 3 lobes split by horizontal & diagonal fissures, split into 10 tertiary bronch (A PALM SAM, LP)i; L lung has 2 lobes split by oblique fissure, split into 8 tertiary bronchi (ASIA ALPS) || **minor** - supply from R&L bronchial aa branches from aorta carrying OXY blood to primary & secondary bronchi; **major** - pulmonary aa from pulmonary trunk carry deOXY blood from RV to tertiary bronchi, bronchioles & lung tissue || pulmonary vv (2 on each side) carrying OXY blood from lungs to LA; R broncial v drains to azygos, L bronchial v drains to accessory hemiazygos v or L superior intercostal v || Ass w/ channels running alongside the bronchioles & bronchi; LNs found near hila called bronchopulmonary nodes; near carina "carina nodes"; near trachea "tracheal nodes" || Detect irritants to lungs || Norepinephrine causes vasocontriction: direct - axons from thoracic paravertebral chain to inn arteriolar smooth muscle cells; indirect - cirulating norepinephrine & epinephrine from adrenal medulla relax bronchiolar smooth muscle cells || Acetylcholine causes bronchilar constriction & vasodilation: Neurons from brain stem -- vagus nn to terminal ganglia of peribronchial plexi ||
 * = **Heart** || Muscular pump for CV system enclosed by pericardium in the mediastinum || Epicardium & myocardium receive OXY blood via RCA & LCA - RCA from right aortic sinus giving branches: anterior R arterial a (includes SA nodal branch), R marginal branch, AV nodal branch, ends as posterior interventricular a; LCA from L aortic sinus giving branches: LAD, circumflex a, L marginal a ||  ||   ||   ||   ||   ||
