Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries.

Together with the Amsterdam albatross, it forms the wandering albatross species complex, which some began referring to more recently as "snowy" [3]. The snowy albatross is one of the two largest members of the genus Diomedea (the great albatrosses), being similar in size to the southern royal albatross. It has the greatest known wingspan of any ...
The Galapagos albatross is critically endangered with a declining population. Today, there are estimated to be around 50,000 to 70,000 individuals in the species.
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
