This blog is intended for students in the health sciences and other students with an interest in cardiovascular, pulmonary and renal physiology and pathophysiology. It is a compilation of original contributions as well as notes I have taken during lectures on these topics and clinical lectures. At the bottom of each post is a box for comments that you are invited to use. Steve Wood, PhD, swood60@gmail.com teaching website: http://www.cvpulmrenal.com
