A companyâs inventory turnover ratio refers to how quickly goods enter and leave storage at the business. Itâs most often used in relation to companies that deal in perishable goods, such as foodstuffs, or high-demand retail items. Itâs easy to calculate in theory, but itâs not always easy to interpret.
The retina is the light-sensitive layer at the back of the eye that is responsible for vision. Blood circulation to most of the retina's surface is primarily through one artery and one vein. If either blood vessel or one of their smaller branches is blocked, blood circulation to the retina can be significantly disrupted. The blockage is called an occlusion.
Without adequate blood flow, the heart is starved of the oxygen and vital nutrients it needs to function properly. The most common symptom of coronary artery disease is angina or chest pain. When one or more of the coronary arteries is completely blocked, a heart attack may occur, which damages the heart muscle. If the blockage occurs more slowly, the heart muscle may create small blood vessels that allow the other coronary arteries to reroute the blood flow. In this case, angina may occur. Top of Page.
