ARTERIAL SYSTEM Meaning and
Definition
-
The "arterial system" refers to the network of blood vessels that carry oxygenated blood pumped by the heart to various tissues and organs throughout the body. It consists of a complex arrangement of arteries of different sizes and types that form an essential part of the circulatory system. Arteries are thick-walled, muscular blood vessels that have a high pressure due to the force exerted by the heart during contraction.
The primary function of the arterial system is to distribute oxygen-rich blood to tissues and organs, ensuring their proper functioning and survival. Oxygenated blood leaves the heart through the largest artery, known as the aorta, which branches into numerous smaller arteries and arterioles. Arteries progressively divide into smaller vessels, forming an extensive network that reaches deep into the tissues.
The arterial system also plays a vital role in regulating blood pressure and maintaining homeostasis. The muscular walls of arteries can expand and contract to adapt to changes in blood flow and pressure, allowing them to control the distribution and volume of blood throughout the body.
Diseases or disorders that affect the arterial system can have severe consequences for overall health. Some common conditions include atherosclerosis (narrowing and hardening of the arteries), hypertension (high blood pressure), and aneurysms (weakening and bulging of arterial walls). Understanding the structure and functions of the arterial system is crucial for diagnosing and treating such conditions, as well as for studying the normal functioning of the circulatory system.

Etymology of ARTERIAL SYSTEM
The word "arterial" is derived from the Latin word "arteria", which refers to a blood vessel. The Latin term, in turn, traces back to the Greek word "artēria", which translates to "windpipe" or "artery". The Greeks associated these blood vessels with the windpipe due to their similarity in appearance. The term "system" comes from the Latin word "systema", meaning "whole composition" or "organized body". Therefore, the term "arterial system" refers to the network of blood vessels that transport oxygenated blood from the heart to various parts of the body.
