The vagus nerve is used to regulate the heartbeat and the muscle movement necessary to keep you breathing. This nerve also regulates the chemical levels in the digestive system so that the intestines can process food and keep track of what types of nutrients are being gained from the food that is taken in.he vagus nerve is used to regulate the heartbeat and the muscle movement necessary to keep you breathing.

which group of elements are niether metals or nonmetals these are te metalloids boron silicon germanium arsenic antimony tellurium these elements in the solid state have characteristics of both metals and non metals their chemistry also has similarities to both metals an non metals 1 person found this useful answered by the wikianswers community
The metalloids or semimetals are located along the line between the metals and nonmetals in the periodic table. The metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Polonium is often considered a metalloid, too.Properties of the Semimetals or Metalloids.The electronegativities and ionization energies of the metalloids are between those of the metals and nonmetals, so the metalloids exhibit characteristics of both classes.Silicon, for example, possesses a metallic luster, yet it is an inefficient conductor and is brittle.roperties of the Semimetals or Metalloids.
