One of the first major discoveries relevant to the field of pulmonology was the discovery of pulmonary circulation.Originally, it was thought that blood reaching the right side of the heart passed through small 'pores' in the septum into the left side to be oxygenated, as theorized by Galen; however, the discovery of pulmonary circulation disproves this theory, which had previously been ...
The unit described as the secondary pulmonary lobule is the lobule most referred to as the pulmonary lobule or respiratory lobule. [25]: 489 [31] This lobule is a discrete unit that is the smallest component of the lung that can be seen without aid. [29] The secondary pulmonary lobule is likely to be made up of between 30 and 50 primary lobules ...
Pulmonary interstitial pressure (Pi) rises as lung volume decreases due to reduced radial tethering of the lung parenchyma. Pi is highest at the base of the lung due to the weight of the above lung tissue. Pi can also rise due to an increased volume of 'leaked' fluid from the pulmonary vasculature (pulmonary edema). An increase in Pi causes ...
The posterior fields can be listened to from the back and include: the lower lobes (taking up three quarters of the posterior fields); the anterior fields taking up the other quarter; and the lateral fields under the axillae, the left axilla for the lingual, the right axilla for the middle right lobe. The anterior fields can also be auscultated ...
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [ 2 ] (swelling or hardening of normally soft tissue) of a normally aerated lung.

Most commonly emphysema refers to the permanent enlargement of air spaces in the lungs, [5] [6] and is also known as pulmonary emphysema. Emphysema is a lower respiratory tract disease, [ 7 ] characterised by enlarged air-filled spaces in the lungs , that can vary in size and may be very large.
