TY - CHAP M1 - Book, Section TI - Gastrointestinal Drugs A1 - Ciccone, Charles D. PY - 2016 T2 - Pharmacology in Rehabilitation AB - The gastrointestinal (GI) tract is responsible for food digestion and the absorption of nutrients and water. Dietary constituents undergo a series of digestive processes as they progress through the GI system. Under normal conditions, the transit time of food and water is adequate to allow the processes of digestion and absorption to take place. Indigestible and nonabsorbable products are eliminated by defecation. SN - PB - F. A. Davis Company CY - New York, NY Y2 - 2024/03/29 UR - fadavisat.mhmedical.com/content.aspx?aid=1135036823 ER -
