Just as it does with food, the body tries to chemically break down medicines as soon as they enter the body. Most drugs taken by mouth enter the stomach or small intestine and then are sent to the liver. The liver contains protein molecules called enzymes that chemically modify drugs and other non-food substances.
Pluto: The Farthest Planet (Usually) Pluto, the ninth planet in our solar system, was not discovered until 1930 and remains a very difficult world to observe because it's so far away. At an average distance of 2.7 billion miles from the Earth, Pluto is a dim speck of light in even the largest of our telescopes. It takes almost 249 years to make one swing around the Sun, in a long looping orbit that takes it above and below the path of the other planets.
1 Neptune is the furthest planet from the sun and the fourth largest. 2  It has a diameter of 30,775 miles (49,528 km) which is four times larger than Earth. 3  Neptune is 30 times further away from the sun than Earth is. 4  The dwarf planet Pluto moves inside Neptune's orbit every 248 years, for periods of 20 years.t spins on its own axis every 16 hours compared to 24 hours on Earth. Due to its far distance from the sun Neptune has an extremely cold outer atmosphere with temperatures averaging around -220C (-364F).
