érrendszeren

érrendszeren is a Hungarian term that translates to "circulatory system" in English. It refers to the complex network of organs and vessels responsible for transporting blood, nutrients, oxygen, carbon dioxide, hormones, and other essential substances throughout the body. This system is vital for maintaining life, as it ensures that every cell receives what it needs to function and that waste products are efficiently removed.

The primary components of the circulatory system include the heart, which acts as a powerful pump, and a vast network of blood vessels. These vessels are broadly categorized into arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart to the rest of the body, while veins return deoxygenated blood back to the heart. Capillaries are the smallest blood vessels, forming a network within tissues where the exchange of gases, nutrients, and waste products occurs between the blood and the cells. The circulatory system is also closely linked with the lymphatic system, which plays a role in fluid balance and immune function. Its continuous operation is crucial for overall health and well-being.
