Fundus and Body constitutes most extensive region of Stomach. There are 4 general regions ( inside to outside ) : Mucosa (Epithelium + Lamina Propria + Muscularis Interna) Submucosa Muscularis Externa (Circular & Longitudinal Smooth Muscle layers) Serosa Important Labels ( Additional to above 4 ) Parietal Cells &  Chief Cells (Gastric Glands) Gastric Pits Oblique Muscle Layer (Characteristic Feature)

The histology of Intrapulmonary bronchi is similar to that of the trachea and extra-pulmonary bronchiole, except that C-shaped cartilage rings are absent here and replaced by cartilage plates. Intrapulmonary Bronchus :  Pseudo-stratified Columnar Ciliated Bronchial Epithelium Cartilage Plates & Seromucous Bronchial Glands Terminal Bronchiole :  Simple Columnar Epithelium  Prominent mucosal folds & well developed smooth muscles Respiratory Bronchiole :  Simple Cuboidal Epithelium  Alveolar Out-pocketings in the wall  Gives rise to alveolar ducts Alveolar Walls :  Out-pocketings of respiratory bronchioles type 1 & 2 Pneumocyets  Also contain Alveolar macrophages  Bands of Smooth muscle fibres in interalveolar septa
