Document Summary

Lecture 3 - lungs, pleura and bronchial lung. Asthma: involves spasm of smooth muscle around the lower airways bronchioles, common triggers include pollen, dust mites, mould, pet dander and cold air. Lungs: left has superior and inferior lobes (oblique ssure separating them) + cardiac notch (medial) from heart pressing on lung, apex at top, base at bottom (sits on top of diaphragm, medial surface has hilum for neurovascular supply. Pulmonary arteries are superior and posterior to veins; pulmonary veins are inferior and anterior to arteries (2) bronchial arteries and veins = bronchial supply for lung parenchyma (non-respiratory), bronchial artery from descending aorta, bronchial vein to azygous veins. Left lung, medial surface: hilum contains pulmonary artery (superior and posterior to veins) and pulmonary veins (anterior and inferior to arteries, lingular notch, deep cardiac impression and indent from arch of aorta. Sympathetic and parasympathetic action on smooth muscles around bronchi, depending on conditions.
