Arteries are part of the circulatory system and are responsible for carrying blood away from the heart and around the body. The arterial blood is oxygenated and this process ensures that every tissue around the body will receive oxygen and nutrients through this blood flow.
Veins are also part of the circulatory system and are responsible for carrying the deoxygenated blood from the tissues back to the heart.
Venous pressure is much lower than the arterial pressure. More specifically, venous pressure ranges from 5 to 8 mmHg, while arterial pressure ranges from 15 to 30 mmHg.
