Artery under the Microscope

Arteries are blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined with smooth tissue that has three layers:

1. The intima is the inner layer lined by a smooth tissue called endothelium.
2. The media is a layer of muscle that lets arteries handle the high pressures from the heart.
3. The adventitia is a connective tissue anchoring arteries to nearby tissue.

The largest artery in the human body 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 referred to as arterioles and capillaries. The pulmonary arteries carry oxygen-poor blood from the heart to the lungs under low pressure, making these arteries unique.
