ARTERIES are blood vessels that convey oxygenated blood away from the heart. To endure blood pressure, they have robust walls with muscle tissue. They can vary their diameter to regulate blood pressure and manage blood flow because of their unique structure.
The largest vein in the body, the VENA CAVA, carries blood from different parts of the body to the heart. It is divided into two sections: the superior vena cava and the inferior vena cava. Blood is carried from the head, neck, arms, and chest by the former, while blood is carried from the legs, feet, and organs in the abdomen and pelvis by the latter.
VEINS transport deoxygenated blood to the heart. Because the pressure in veins is so much lower than in arteries, they have thinner walls. As the volume of fluid in the veins grows, they can widen (dilate). They use valves to keep the blood moving, notably in the veins of the legs.
