Research Article: Effects of Hydrostatic Pressure on Carcinogenic Properties of Epithelia

Date Published: December 30, 2015 Publisher: Public Library of Science Author(s): Shinsaku Tokuda, Young Hak Kim, Hisako Matsumoto, Shigeo Muro, Toyohiro Hirai, Michiaki Mishima, Mikio Furuse, Kjetil Tasken. http://doi.org/10.1371/journal.pone.0145522 Abstract The relationship between chronic inflammation and cancer is well known. The inflammation increases the permeability of blood vessels and consequently elevates pressure in the interstitial … Continue reading

The Interaction of Hydrostatic and Osmotic Pressures

OpenStax Anatomy and Physiology The normal unit used to express pressures within the cardiovascular system is millimeters of mercury (mm Hg). When blood leaving an arteriole first enters a capillary bed, the CHP is quite high—about 35 mm Hg. Gradually, this initial CHP declines as the blood moves through the capillary so that by the … Continue reading
