Adult Studies: In a double-blind study of three different dosing regimens of ZOFRAN Injection, 0.015 mg/kg, 0.15 mg/kg, and 0.30 mg/kg, each given three times during the course of cancer chemotherapy, the 0.15-mg/kg dosing regimen was more effective than the 0.015-mg/kg dosing regimen.
Peristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward. Earthworms use a similar mechanism to drive their locomotion, and some modern machinery imitates this design.
Peristalsis is the process of the movement of food through the GI tract. So, digestion begins in the mouth when you chew and ends in the large intestine 18 to 20 hours later. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
