CIRCULATORY SYSTEM Meaning and
Definition
-
The circulatory system refers to the complex network of organs, vessels, and tissues that play a crucial role in transporting blood, nutrients, gases, hormones, and waste products throughout the body of an organism. This system is essential for the overall functioning and survival of numerous organisms, including humans.
At its core, the circulatory system consists of the heart, blood vessels (including arteries, veins, and capillaries), and blood. The heart acts as a vital pump that propels the blood through the vessels and ensures its circulation. The blood vessels, branching throughout the body in an intricate network, facilitate the flow of blood and transport it to various organs and systems.
Within this system, there are two major components: the systemic circulation and the pulmonary circulation. The systemic circulation refers to the pathway through which oxygenated blood is transported from the heart to the different tissues and organs of the body, providing them with vital nutrients and oxygen. In contrast, the pulmonary circulation involves the circulation of deoxygenated blood from the heart to the lungs, where it is oxygenated and then returned to the heart.
Working in harmony, the circulatory system maintains a delicate balance in the body by regulating blood pressure, delivering oxygen and nutrients to cells, removing metabolic waste, enabling immune responses, and facilitating the transportation of hormones to their target sites. Without a fully functioning circulatory system, the body would not receive the necessary resources to sustain life.

Etymology of CIRCULATORY SYSTEM
The word "circulatory" comes from the Latin word "circulatorius", which means "pertaining to a circle". This word is derived from the Latin word "circulus", meaning "circle" or "ring". The term "system" comes from the Latin word "systema", which originated from the Greek word "sustēma" meaning "a whole compounded of several parts". Therefore, the etymology of the word "circulatory system" combines the Latin word for circle with the Greek term for a whole composed of different parts.
