A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [1] [2] These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment. Veins and lymphatic vessels drain along the edges of the segment.
Ewart's sign is a set of findings on physical examination in people with large collections of fluid around their heart (pericardial effusions). [2]Dullness to percussion (described historically as "woody" in quality), egophony, and bronchial breath sounds may be appreciated at the inferior angle of the left scapula when the effusion is large enough to compress the left lower lobe of the lung ...
The left bronchus has no eparterial branch, and therefore it has been supposed by some that there is no upper lobe to the left lung, but that the so-called upper lobe corresponds to the middle lobe of the right lung. The left main bronchus divides into two secondary bronchi or lobar bronchi, to deliver air to the two lobes of the left lung ...
The left lung is divided into two lobes, an upper and a lower lobe, by the oblique fissure, which extends from the costal to the mediastinal surface of the lung both above and below the hilum. [1] The left lung, unlike the right, does not have a middle lobe, though it does have a homologous feature, a projection of the upper lobe termed the ...
Bronchial veins are thereby part of the bronchial circulation, carrying waste products away from the cells that constitute the lungs. The bronchial veins are counterparts to the bronchial arteries. However, they only carry ~13% of the blood flow of the bronchial arteries. [1] The remaining blood is returned to the heart via the pulmonary veins. [1]
Consequently the vessels wall are more stretched so the caliber of the vessels increases causing an increase in flow due to lower resistance. Zone 4 can be seen at the lung bases at low lung volumes or in pulmonary edema. Pulmonary interstitial pressure (Pi) rises as lung volume decreases due to reduced radial tethering of the lung parenchyma ...
Given that many chronic health conditions, including arthritis and autoimmune diseases, are driven by high levels of inflammation, physician Mark Harper, M.D., Ph.D. believes cold water immersion ...
The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.
