Solisvaltimoiden
Solisvaltimoiden, commonly known as veins, are a critical component of the circulatory system in vertebrates. Their primary function is to transport deoxygenated blood from the body's tissues back to the heart. This contrasts with arteries, which carry oxygenated blood away from the heart. Veins are characterized by their thinner walls and less muscular structure compared to arteries, as the blood pressure within them is significantly lower.
Many veins, particularly those in the limbs, possess valves. These flap-like structures are crucial for preventing
The venous system is extensive, forming a network that encompasses the entire body. From small venules that
