varusüsteem

Varusüsteem refers to the circulatory system in Estonian. It is a biological system responsible for the circulation of blood, nutrients, oxygen, and other vital substances throughout the body of an organism. This system is crucial for maintaining life and ensuring that all cells receive what they need to function, while also removing waste products.

The human circulatory system is a complex network composed of the heart, blood vessels, and blood. The heart acts as a powerful pump, propelling blood through the arteries, which carry oxygenated blood away from the heart to the rest of the body. Veins then return deoxygenated blood back to the heart. Capillaries are tiny vessels that connect arteries and veins, forming a vast network where the exchange of gases, nutrients, and waste products occurs between the blood and the body's tissues.

In addition to transporting oxygen and nutrients, the varusüsteem plays a role in regulating body temperature, transporting hormones, and protecting the body against infection through the immune system's components circulating within the blood. Its efficient functioning is vital for overall health, and disruptions to the varusüsteem can lead to various diseases and health conditions.
