Verenkiertoaan

Verenkiertoaan is a Finnish term that translates to "blood circulation" or "blood flow." It refers to the continuous movement of blood throughout the body, which is essential for life. This process is driven by the heart, a muscular organ that pumps blood through a network of blood vessels, including arteries, veins, and capillaries.

The circulatory system has two main parts: the pulmonary circulation and the systemic circulation. Pulmonary circulation involves the movement of blood between the heart and the lungs. Here, blood releases carbon dioxide and picks up oxygen. Systemic circulation then distributes this oxygenated blood from the heart to the rest of the body's tissues and organs, delivering nutrients and removing waste products. Deoxygenated blood then returns to the heart to begin the cycle again.

Efficient verenkiertoaan is crucial for maintaining overall health. It ensures that all cells receive the oxygen and nutrients they need to function and that waste products are effectively removed. Disruptions to blood circulation can lead to various health problems, highlighting its vital role in the body's physiology.
