STRUCTURAL AND MORPHOLOGICAL CHANGES OF PULMONARY CIRCULATION ARTERIES IN EXPERIMENTAL METABOLIC CONDITIONS

It is well known that the circulatory system integrates all organs and tissues of the body into a single functional whole. It transports essential nutrients, removes metabolic waste products, and provides protection against foreign substances. Metabolism (from the Greek metabole — change) represents a complex of enzymatic reactions occurring within cells. As a result of metabolism, substances and energy necessary for organic life are produced. The activity of the cardiovascular system plays a crucial role in the implementation of these processes.
