Left heart simulation for applications in teaching and scientific research. A model is a logical description of how a system works or how their components behave. The tools of the dynamic modeling facilitate the construction of the models. The aim of this article is to show the development and results of the operation of an interactive model of the cardiocirculatory system physiology for the use of students and others interested in cardiovascular physiology. The model used is a simple model of four components, and simulates the following variables and parameters: a) volume variations of left atrial (LA) and left ventricle (LV); b) pressure variations in LA, LV and aorta (Ao); c) the flow across mitral (MV) and aortic valve (AoV), and d) imitates the "Windkessel effect" in Ao. The modeling environment "Extend" was used, which provides an integrated structure for the simulation models construction and the development of new simulations tools. The right heart and the pulmonary circulation are not considered. The model's results simulate the general characteristics of the left heart and of the arterial circulation, considering different physiological and pathological situations.
