Lung anatomy

Question 1

lymphatic drainage of lungs

Answer 1

from the pleura to the hilum of the lung, to bronchopulmonary nodes
then into tracheobronchial (found at bifurcation) and then to the paratracheal and mediastinal lymph trunks
finally into brachiocephalic veins

Question 2

where are the parasympathetic ganglia located

Answer 2

pulmonary plexuses and bronchial tree

Question 3

parasympathetic fibres innervate

Answer 3

smooth muscle in bronchial tree and pulmonary vessels and the pulmonary glands
also carry sensation from the stretch receptors in bronchial muscles, inter alveolar connective tissue, baroreceptors in pulmonary arteries and chemoreceptors in pulmonary veins

Question 4

sympathetic fibres innervate

Answer 4

innervate smooth muscle of the bronchial tree, pulmonary vessels and secretory glands of bronchial tree

Question 5

parietal pleura innervated by

Answer 5

phrenic and intercostal nerves

Question 6

parts of the body drained by the thoracic duct vs. not

Answer 6

not drained by thoracic duct = right arm, right side of neck, right side of head and right upper abdomen

Question 7

what is the region not drained by the thoracic duct drained by

Answer 7

the lymphatic duct

Question 8

where does the thoracic duct drain into

Answer 8

start of the left brachiocephalic vein

Question 9

where does lymph from the head, neck, arms thorax drain into

Answer 9

left jugular, sublcavian, mediastinal trunks-> thoracic duct or large veins
right side trunks -> directly into large veins
