Carbon dioxide and methane are potent greenhouse gases. They cause heating of the lower atmosphere, by trapping sunlight, that results to climate change. Due to the higher melting and boiling temperatures of phosphorus, it is rare that it occurs as gas in room temperatures. Phosphorus, therefore, does not pose a great threat of climate change.
The coronary arteries supply blood to cardiac tissue. The left ventricle chamber of the heart requires the greatest amount of blood supply to keep it working.
Coronary arteries
The heart muscle receives blood from the coronary arteries. The heart muscle needs oxygen-rich blood in order to operate, just like all other bodily components do. Blood that lacks oxygen must also be transported away. Outside of the heart, the coronary arteries encircle the organ.
The coronary artery that is blocked the most frequently is the LAD artery. The interventricular septum, and therefore bundle branches of the conducting system, receive their primary blood supply from it.
