Hilum of the Lung Flashcards
__________ arteries and veins deal with gas exchange and the circulation of blood between the heart and lungs.
Pulmonary
__________ arteries and veins are the vascular supply to the structural elements of the lungs, such as the bronchial tree.
Bronchial
A wide vessel that arises from the right ventricle and after a short 5cm course bifurcates into the left and right pulmonary arteries.
Pulmonary trunk
What is the function of the ductus arteriosum?
It’s a blood vessel connecting the pulmonary arteries to the aorta to surpass the lungs in developing fetuses.
What is the ligamentum arteriosum?
Fibrous remnant of the fetal ductus arteriosum, that is located at the bifurcation of the pulmonary trunk into the pulmonary arteries.
Branch from the pulmonary trunk and deliver deoxygenated blood to the pulmonary capillaries of the lungs.
Pulmonary arteries
Transport oxygenated blood from the pulmonary capillaries to the left atrium of the heart.
Pulmonary veins
Arise from the aorta to supply the bronchial tree parenchyma.
Bronchial arteries
Lymph from the lobes of the lungs drains into _________ and _______________ _____ and then into the ____________ ______ and into the ___________ ______.
Pulmonary, bronchopulmonary nodes, tracheobronchial nodes, paratracheal nodes.
Lymph enters the systemic circulation through either the _____ __________ ____ or the ________ ____.
right lymphatic duct, thoracic duct
The _________ _______ of nerves follows the trachea and bronchial tree, providing parasympathetic and sympathetic innervation to the smooth muscle and glands of the lung.
pulmonary plexus
Which type of innervation causes bronchoconstriction and bronchial gland secretion; supplied by branches of the vagus nerve (CN-X)?
Parasympathetic
Which type of innervation causes bronchodilation and inhibition of bronchial gland secretion; supplied by postganglionic fibers from T1-T4 and cervical ganglia?
Sympathetic
