Video: The Sensory System: Definition, Parts & Functions. This lesson will examine how the sensory systems are integrated and how they function as a whole. Instead of telling you ears hear and eyes see, we will examine how these systems are actually very similar in terms of reception, signals, and translations.
Mercury is a silvery-white metal element that is liquid at ordinary room temperature; it has no taste or smell. It occurs as metallic mercury (Hg), as cinnabar (HgS) and in perhaps 25 other in organic mineral compounds. The elemental form (Hg) vaporizes at any temperature down to almost 40Â° below zero. The vapor also has no taste or smell. The specific gravity of mercury is 13.546; therefore, it is heavier than lead and, like lead and other heavy metals, it is a potent poison. Exposure to metallic mercury or mercury compounds, even in small quantities over a period of time, can cause severe poisoning.
Mercury: Get This Heavy-Metal Poison Out of Your Body. IF YOU ARE HEAVY, it could be making you sick and tired and age prematurely. And I donât mean heavy with fat â¦ I mean heavy with heavy metalsâlike mercury. Unfortunately, toxic mercury problems are common. Along with polar bears, beluga whales, ducks, otters, panthers, and all river fish as well as most large ocean fish, we humans are poisoning ourselves with mercury at ever increasing rates.
