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.
In large quantities or over time, alcohol causes severe disruption to the endocrine system, upsetting the delicate balance of such critical hormones as estrogen, testosterone, prolactin and progesterone. These four hormones must be precisely regulated if the male or female reproductive system is to work correctly.
