blodkärlsnätverket
Blodkärlsnätverket, also known as the circulatory system, is a vital network of blood vessels that transports blood throughout the body. This system is comprised of arteries, veins, and capillaries, each playing a crucial role in maintaining life. 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 tiny, thin-walled vessels that connect arteries and veins, facilitating the exchange of oxygen, nutrients, and waste products between the blood and the body's tissues.
The primary function of the blodkärlsnätverket is to deliver oxygen and nutrients to all cells and organs,
Diseases affecting the blodkärlsnätverket, collectively known as cardiovascular diseases, are a leading cause of mortality worldwide.
