ANATOMY OF THE CARDIOVASCULAR SYSTEM

Abstract

This article analyzes the anatomical and functional structure of the cardiovascular system from a systematic perspective. The topographical position of the heart in the thoracic cavity, the layers of its wall, the structure of the atria and ventricles, the valvular apparatus, the conduction system, coronary circulation, and the morphological features of the major blood vessels are discussed in sequence. The main purpose of the article is to explain the anatomy of the heart and blood vessels to dentistry students not only descriptively, but also through clinical and functional reasoning. The analysis shows that a profound knowledge of cardiac anatomy is important not only for understanding cardiovascular diseases, but also for making correct dental decisions related to anesthesia, arterial pressure, hemodynamic stability, the risk of infective endocarditis, and systemic diseases. The heart is a four-chambered muscular organ whose valves maintain one-way blood flow, while its conduction system ensures rhythmic contraction. Variations in the anatomy of the coronary arteries and major vessels are of considerable clinical significance. For this reason, the relationship among anatomical norm, morphological variation, and clinical relevance is presented as the central idea of the article
