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.
No. Advil, or ibuprofen, is NOT safe for dogs or cats. Though relatively safe for people, ibuprofen can be toxic for dogs and has a relatively narrow margin of safety, meaning that it is safe for dogs only within a very narrow dosage range. Source: http://m.petmd.com/dog/condition...
