Coronary Artery Disease. The coronary arteries are the blood vessels that supply the heart with oxygen and nutrients. When there is build up of cholesterol (plaque) inside the walls of the coronary arteries, the blood flow to the heart decreases.Usually there are no symptoms when the blockage is small.his completely blocks the flow of blood in the artery. The area of heart muscle supplied by that artery then becomes damaged due to lack of oxygen and nutrients. Blockages of any size can cause a heart attack (myocardial infarction).Coronary artery disease is very common throughout the world.
A function key is a key on a computer or terminal keyboard which can be programmed so as to cause an operating system command interpreter or application program to perform certain actions, a form of soft key. On some keyboards/computers, function keys may have default actions, accessible on power-on.
I am in a bit of a pickle. I am using a Dell keyboard with Mac OS X, and I would like access to my function keys while I'm using Terminal. A friend of mine has a new Mac keyboard which has a Fn key right on it, but when I press the same location on my keyboard my cursor simply turns into a question mark, apparently this is treated as the 'help' key from older model mac keyboards.
