Electromagnetic spectrum refers to the full range of all frequencies of electromagnetic radiation and also to the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Devices used to measure an electromagnetic spectrum are called spectrograph or spectrometer.
Another way that alcohol affects the endocrine system is by interfering with how the body absorbs calcium, a chemical needed for strong bones. As a result, people who drink heavily may be at a higher risk for osteoporosis, a disease in which bone density declines.
Upper gastronintestinal diseases, particularly gastritis, ulcer, and cancer, have often and long been blamed on drinking alcohol. For acute gastritis, inflammation of the stomach lining, this is an accepted truth for those who drink large quantities quickly (binge drinking) of high-strength potables, spirits. Chronic gastritis may have an entirely different cause, as we shall see. Chronic alcohol abuse increases the risks of esophageal and, perhaps, stomach cancer.
