Document Summary
Alveoli: between alveolar sac and bronchiole is an alveolar duct, many ducts per bronchiole. Lungs: right lung has three large divisions, superior, middle, and inferior lobes, middle lobe is more medial, can have ten tertiary bronchi, therefore 10 bronchopulmonary segments. Internal intercostals depress the ribs to aid in exhalation: much smaller than diaphragm. Lines the pericardial space vertebra with pericardium: visceral pericardium (epicardium) is the most external layer of the heart wall. Layer of loose connective tissue that supports mesothelium: function, protects the heart, prevents heart from sudden over-dilation due to overfilling, stabilizes vigorously beating heart. It has branching arteries that lead to different segments of the body: each somite develops into a body segment that is. Internal tunica in capillary is similar in quality but not as thick as the internal tunica in arteries and veins: tunica interna. Large veins (>10mm) are more rigid: typical structure.
