Absorption | Process by which drugs are transferred from the site of entry into the body to the bloodstream. |
Anorexia | Lack or loss of appetite for food. |
Anthropometric | Measurements of the body and body parts. |
Aspiration | Misdirection of oropharyngeal secretions or gastric contents into the larynx and lower respiratory tract. |
Basal metabolism | Amount of energy required to carry out involuntary activities of the body at rest. |
Body mass index (BMI) | Ratio of height to weight. |
Calorie | Measure of heat, or energy; kilocalorie, commonly referred to as a calorie, defined as the amount of heat required to raise 1kg of water 1 degree Celsius. |
Carbohydrate | Organic compounds (commonly known as sugars and starches) that are composed of carbon, hydrogen and oxygen; the most abundant and least expensive source of calories in the diet worldwide. |
Cholesterol | Fat-like substance found only in animal tissues; it is important for cell membrane structure, a precursor of steroid hormones, an constituent of bile; high serum cholesterol levels are a risk factor in the development of atherosclerosis. |
Digestion | GI system's breakdown process of food into particles small enough to pass into the cells and be used by the cells. |
Dysphagia | Difficulty swallowing or inability to swallow. |
Ketosis | An abnormal accumulation of ketone bodies that is frequently associated with acidosis. |
Lipid | Group name for fatty substances, including fats, oils, waxes and related compounds. |

NPO | Nothing by mouth. (Latin: nil per os) |
Nutrient | Specific biochemical substance used by the body for growth development, activity, reproduction, lactation, health maintenance, and recovery from illness or injury. |
Nutrition | Study of the nutrients and how they are handled by the body, as well as the impact of human behavior and environment on the process of nourishment. |
Obesity | Weight greater than 20% above ideal body weight. |
Protein | Vital component of every living cell; composed of carbon, hydrogen, oxygen, and nitrogen. |
Recommended Dietary Allowance (RDA) | Recommendations for average daily amounts of essential nutrients that healthy population groups should consume over time. |
Trans Fat | Partially hydrogenated liquid oil, trans fat raises serum cholesterol. |
Triglycerides | Predominant form of fat in food and the major storage from of fat in the body. |
Vitamins | Organic substances needed by the body in small amounts to help regulate body processes; are susceptible to oxidation and destruction |
Waist circumference | A numerical measurement of the waist, used to assess an individual's abdominal fat and establish ideal body weight. |
Acid | Substance containing a hydrogen ion that can be liberated or released. |
Acidosis | Condition characterized by a proportionate excess of hydrogen ions in the extracellular fluid, in which the pH falls below 7.35. |
Active Transport | Movement of ions or molecules across cell membranes, usually against a pressure gradient and with the expenditure of metabolic energy. |

Base | Substance that can accept or trap a hydrogen ion; synonym for alkali. |
Buffer | Substance that prevents body fluid from becoming overly acid or alkaline. |
Capillary Filtration | Passage of fluid across the wall of the capillary; results from the force of blood "pushing: against the walls of the capillaries. |
Cation | Ion that carries a positive electric charge. |
Colloid Osmotic Pressure | Pressure exerted by plasma proteins on permeable membranes in the body; synonym for oncotic pressure. |
Dehydration | Decreased water volume in body tissue. |
Diffusion | Tendency of solutes to move freely throughout a solvent from an area of higher concentration to an area of lower concentration until equilibrium is established. |
