An arterial line is usually inserted into the radial artery in the wrist, but can also be inserted into the brachial artery at the elbow, into the femoral artery in the groin, into the dorsalis pedis artery in the foot, or into the ulnar artery in the wrist.
Arterial walls have three layers: 1  The endothelium (pronounced: en-doh-THEE-lee-um) is on the inside and provides a smooth lining for blood to flow over as it moves through the artery. 2  The media is the middle part of the artery, made up of a layer of muscle and elastic tissue.
