Usually they use one of the leg veins (saphenous vein), but they can also other veins or the radial artery. They usually do it all (harvesting of the vein and the heart surgery) all in one surgery. CABG's are reserved these days for patients with severe coronary disease and heart failure. In the old days, they used to crack the chest all the way open to operate on the heart, but these days, they are using their fancy machines (with robot arms and cameras, that's how an internist would describe it anyways 😉 ) to make even this procedure less invasive.

CABG (coronary artery bypass graft) surgery uses healthy blood vessels to bypass diseased coronary arteries. Since it's such an invasive procedure, usually the surgeon will bypass any arteries that would cause trouble in the future.
The first "bypass" is the LIMA (left internal mammary artery), which is typically grafted to the LAD (left anterior descending [coronary] artery), distal to the occlusions. Portions of saphenous veins are usually used next, to jump over diseased parts of other coronary arteries.
During the procedure, another kind of "cardiac bypass" is used. The heart is stopped (so the surgeon can sew blood vessels), and a heart-lung machine is hooked up that oxygenates and pumps blood. Catheters are placed in the superior and inferior venae cavae and the ascending aorta to effectively bypass the heart and lungs during surgery.
The best experience I've had in medical school is when I got to perform a median sternotomy... cardiac surgery is awesome.

The LAD is a coronary artery which provides oxygenated blood to a large part of the left ventricle and interventricular septum. Since it is a large caliber artery, it's also a prime target for atherosclerosis and is easy to bypass.
Innervation of the heart is a totally different kettle of fish.
