What is the relationship between the circulatory system and the cardiovascular system?
The phrase circulatory system and the cardiovascular system are often used interchangeably to describe the body system that pumps blood from the heart throughout the body. Although it is a general function of the cardiovascular system, it is only one function of the circulatory system. The circulation system is a system that circulates not only blood but lymphatic, hormones and nutrients between the body tissues and eliminates the by -products of cellular metabolism. The cardiovascular system and the lymphatic system are therefore subdivision of the circulatory system that includes heart, blood vessels such as arteries and veins, and blood itself, as well as lymphatic vessels, lymph nodes and water fluid known as a lymph. Both are usable in discussing blood and nutrient circulation. The purpose of the blood circulation is to distribute oxygen, glucose, electrolytes such as sodium and potassium and other nutrients to organs, muscles and other body tissues through arteries and capillaries. At the same time, the blood that has been exhausted from these nutrients is returned by capillaries to the veins andThey go back to the heart. The heart then pumps this blood into the lungs to destroy carbon dioxide, the main metabolic by -product and obtain a fresh oxygen supply.
These are the primary functions of the circulatory system and the reason why the circulatory system and the cardiovascular system tend to mean the same, while the lymphatic system tends to differentiate from the cardiovascular system. It can be because the cardiovascular system can be considered a closed loop system, which means that blood circulated inside is limited to heart and blood vessels. Therefore, it cycles continuously through the system without input or output.
Thelymphatic system, on the other hand, is an open system, which means it consists of a network of lymphatic vessels and nodes or organs that emit lymph from the system and into the bloodstream. Its function is to eliminate waste products that accumulate in the body tissues, from pathogens and toxins to water and other excess tecutins. The lymphatic system also contributes to the function of the cardiovascular system. Specifically, it transmits hormones, nutrients and oxygen found in the blood to tissues that require it when the waste produced during the metabolism of these substances back into the bloodstream. For this purpose, the lymphatic system is often considered to be the division of the circulatory system.
