#circulatory system

• Angiology — A branch of internal medicine and specialized anatomy that deals with the structural study, diagnosis, treatment, and prevention of disorders affecting the well-defined circulatory system, encompassing arterial, venous, and lymphatic networks. This clinical discipline plays a fundamental role in managing peripheral vascular pathologies, such as atherosclerosis obliterans, deep vein thrombosis, chronic lymphatic insufficiency, and systemic vasculitis.
• Aoria — A rare medical term used to describe the congenital absence, severe atrophy, or lack of structural development of the aorta, the primary artery of the human body. This extremely severe pathological phenomenon directly affects the systemic circulation and requires complex surgical intervention immediately after birth to ensure organism survival.
• Aorta — The largest artery of the human and mammalian body, originating from the left ventricle of the heart and distributing oxygenated blood throughout the organism via its branches. Its resilient, elastic paired structure allows it to withstand high cardiac ejection pressures, making it essential for maintaining systemic blood flow.
• Artery — A blood vessel with elastic and contractile walls that carries oxygenated blood away from the heart to the peripheral tissues and organs of the body (with the exception of the pulmonary artery, which carries deoxygenated blood). In an extended or figurative sense, the term designates a main line of communication, a street of great urban importance, or a major transport route (road, rail, river) that ensures the intense and vital circulation of goods, people, or information flows within a region.
• Artery — An elastic and muscular blood vessel through which blood is conducted from the heart toward the periphery of the organism; (figuratively) a main communication route, road, avenue, or transport path of major structural importance ensuring the intense circulation of goods, vehicles, or people within a region or urban network.
