Cardiovascular agents affect the tone of pulmonary arteries and veins in precision-cut lung slices.

PLoS ONE, 2011
IntroductionCardiovascular agents are pivotal in the therapy of heart failure. Apart from their action on ventricular contractility and systemic afterload, they affect pulmonary arteries and veins. Although these effects are crucial in heart failure with

Anatomic Study of Number of Pulmonary Veins Draining into the Left Atrium and Their Variations

Journal of Medical Sciences and Health, 2020
Introduction: Pulmonary veins originate from the alveolar capillary plexus and carry oxygenated blood to the left atrium. The fibrous pericardium is perforated by the pulmonary veins and they drain separately in the posterosuperior aspect of the left ...
