Breaking these large molecules into smaller components involves: 1  movement: propels food through the digestive system. 2  secretion: release of digestive juices in response to a specific stimulus. 3  digestion: breakdown of food into molecular components small enough to cross the plasma membrane.
Over-the-counter pain relievers, like Advil (ibuprofen), Aleve (naproxen sodium) and Tylenol (acetaminophen), are presumed to be safe. Since they don't require a prescription, directions and warnings aren't always taken seriously.
â AdvilÂ® is a registered trademark of Wyeth, LLC. 1  Aleve has less frequent dosing and fewer pills than other common, over-the-counter pain relievers when pain persists. 2  Compare it! 3  Aleve is available without a prescription, so itâs easy to get pain relief that can last all day.
