The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue and has three layers, those three layers are:

The intima: is the inner layer lined by a smooth tissue called endothelium.

The media: is a layer of muscle that lets arteries handle the high pressures from the heart.

The adventitia: is the connective tissue anchoring arteries to nearby tissues.

The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries. The pulmonary arteries carry oxygen-poor blood from the heart to the lungs under low pressure, making these arteries unique.

Veins are blood vessels located throughout your body that collect oxygen poor blood and return it to your heart. Veins are part of your circulatory system. They work together with other blood vessels and your heart to keep your blood moving. Veins hold most of the blood in your body. In fact, nearly 75% of your blood is in your veins.

Artery vs Veins:

Arteries carry blood away from the heart

Veins carry blood towards the heart.

Arteries carry oxygenated blood

Veins carry deoxygenated blood.

Arteries have thick walls with muscle tissue.

Veins have thinner walls and use valves to keep your blood flowing.

With the exception of pulmonary blood vessels: Carry blood from the right side of the heart to the lungs.
