Digestion
Mechanical and chemical processes necessary to convert food to an absorbable state
Fats
Lipid organic substances composed of carbon, hydrogen, and oxygen
Fiber
Component of food that adds bulk to the diet and is not broken down by digestion
Gastric residual volumes (GRVs)
Volume aspirated from the stomach as a way to assess tolerance of eternal feeding
Macronutrients
Carbohydrates, proteins, and fats; used by the body in large amounts
Metabolism
a) Chemical reactions in the cells that produce heat as a by-product; (b) Breakdown of a drug (usually in the liver) to an inactive form

Small-bore feeding tubes
Flexible tubes of small diameter designed for comfort during tube feeding./Small-bore tubes are placed into the stomach (e.g., NG, gastrostomy) or small bowel (e.g., ND, NJ, jejunostomy, percutaneous endoscopic jejunostomy, needle-catheter jejunostomy) and are used for feeding or administering medication.

Unsaturated fats
Fats with a single hydrogen atom missing from each of two side-by-side carbon atoms
(Double bond)
Vitamins
Organic compounds that do not supply energy but are necessary to the body in small amounts for growth, development, maintenance, and reproduction
