ANATOMY 1 Lecture Notes - Lecture 12: Alveolar Cells, Simple Squamous Epithelium, Bronchopulmonary Segment
Document Summary
Each lung surrounded by pleural membrane (2 layers) Parietal pleura = superficial layer attaching to wall of thoracic cavity. Visceral pleura = layer actually attaching to lung surface. Contains lubricating fluid ( pleural fluid ) lung @ the hilum the apex of the lung lies superiorly to the medial third of the clavicles. Root of the lung = bronchi, blood vessels, lymphatic vessels, nerves entering the. *the lungs do not completely fill the pleural cavity of the thorax. Each lobe of the lung receives its own lobar (secondary) bronchus. => only area of lungs that can be palpated. Right main bronchi => 3 lobar bronchi (superior, middle, inferior) left main bronchi => 2 lobar bronchi (superior, inferior) *10 segmental bronchi in each lung lobules. Small compartments within bronchopulmonary segments of lungs. Bronchopulmonary segment = segment of lung tissue that each segmental bronchus supplies. Contains lymphatic vessel, arteriole, venule, terminal bronchiole branch.
