Detailed explanation-1: -The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
Detailed explanation-2: -Generally, veins carry deoxygenated blood from the body to the heart, where it can be sent to the lungs. The exception is the network of pulmonary veins, which take oxygenated blood from the lungs to the heart.
Detailed explanation-3: -As cells use the oxygen and nutrients delivered by the arteries they create waste products, such as carbon dioxide. The veins then pick up this waste and deliver it around the body for it to be disposed of and then deliver the deoxygenated blood back to the heart.
Detailed explanation-4: -Arteries carry blood away from the heart and veins carry blood back to the heart.
Detailed explanation-5: -The valves open and close to help blood move along its path: Blood that needs oxygen flows from your body into the right atrium. It then flows through the tricuspid valve to the right ventricle. The right ventricle pumps the blood through the pulmonary valve and into your lungs, where it picks up oxygen.
