SYSTEMIC HEART Meaning and
Definition

Systemic Heart:
The term "systemic heart" refers to a specific organ found in some animals, primarily invertebrates and lower vertebrates, that functions as the main pump for circulating oxygenated blood throughout the entire body. This type of heart is distinct from a "pulmonary heart," which is involved in pumping blood exclusively to the lungs. The systemic heart plays a crucial role in maintaining the overall circulation of oxygen, nutrients, and waste products within the organism.
Typically, the systemic heart consists of one or more chambers that contract rhythmically to pump blood out of the heart and into the systemic circulatory system. In most animals, the systemic heart receives oxygenated blood from the respiratory organs or gills and delivers it to the systemic arteries, which then distribute it to various tissues and organs. Simultaneously, the deoxygenated blood returns to the heart through systemic veins to undergo oxygenation again.
The systemic heart ensures a continuous flow of blood necessary for cellular respiration, providing vital oxygen and nutrients to different organs and eliminating metabolic waste. This organized and coordinated pumping action ensures efficient circulation throughout the body, enabling proper functioning of diverse physiological processes. The systemic heart's structure and functionality may vary across species, reflecting evolutionary adaptations and the specific metabolic requirements of different organisms.
In summary, the systemic heart is a specialized organ responsible for pumping oxygenated blood to supply various tissues and organs within an organism, playing a crucial role in maintaining systemic circulation and overall physiological well-being.

Etymology of SYSTEMIC HEART
The term "systemic heart" does not have a specific etymology, as it is a combination of two words, "systemic" and "heart".
The word "systemic" derives from the Late Latin word "systemicus", which comes from the Greek word "sustēmatikós", meaning "relating to a whole". Over time, the term evolved in English to refer to something related to or affecting the entire system or body.
On the other hand, the word "heart" has Old English roots, deriving from the Proto-Germanic word "khertan" and ultimately from the Proto-Indo-European base "kerd". It has long been associated with the organ responsible for pumping blood in humans and animals, and by extension, it is metaphorically used to represent emotions, love, or core essence.
