Passage of a substance into the interior of another substance.
Passage of fluids or substances through tissues.
Attenuation of radiation energy by the substance through which it passes.
Retention or holding or incorporation of oil or fat by a food product which has been fried.
Transport of the products of digestion from the intestinal tract across the cell membranes that comprise the gut, and into the blood.
The process by which substances are absorbed through the intestinal tract into the bloodstream to be used by the body.
In nutrition, the movement of digested food from the lumen of the intestine into intestinal cells, and from there, into the bloodstream for distribution to other parts of the body.
The process by which a liquid is taken into a solid.
The process of taking into the body substances such as proteins or fats which have been digested form food and enter the bloodstream form the stomach and intestines.
The process by which nutrients are taken up by the intestines and are passed into the bloodstream.
The process by which the body assimilates nutrients via the digestive tract to the bloodstream for nourishing the cells of the body.
Nutrients in the diet are absorbed by cells lining the gastrointestinal tract (enterocytes) by one of three mechanisms: (1) active transport, (2) facilitated diffusion, and (3) passive diffusion. The absorption of both micro- and macronutrients is described as separate entries.
Absorption is the movement of a nutrient or other substance from within the lumen of the gastrointestinal tract to the bloodstream via either the portal circulation or the lymphatic system. In general, water- soluble nutrients are absorbed via the portal circulation and lipid- soluble nutrients are absorbed via the lymphatic system. The primary mechanisms of nutrient absorption are diffusion, facilitated diffusion, and active transport.
Incorporation of matter by other matter, as in the dissolving of a gas in a liquid or the taking up of a liquid by a porous solid; the passage of substances into tissues, as in the passage of digested food into the intestinal cells.
Process by which digested food nutrients move through villi of the small intestine into the blood.
The uptake of fluids or other substances by the tissues of the body. Digested food is absorbed into the blood and lymph from the alimentary canal. Most absorption of food occurs in the small intestine, in the jejunum and ileum, although alcohol is readily absorbed from the stomach. The small intestine is lined with minute fingerlike processes, which greatly increase its surface area and therefore the speed at which absorption can take place.
Uptake by the body tissues of fluids or other substances. For example, food is absorbed from the digestive tract into the blood and lymph systems. Food is absorbed mainly in the small intestine (jejunum and ileum) which is lined by multiple villi that increase its surface area.
The physiological mechanism of drug absorption involves the movement of the drug into the biological system with the intention of delivering it to a specific tissue or organ.
The phenomenon wherein radiation transfers a portion or its entire energy to another material as it traverses through is known as energy deposition.
It involves the transportation of a vitamin from the digestive system to the bloodstream.
The mechanism through which fluids or other substances are assimilated into bodily tissues is referred to as absorption. This term is frequently used to describe the uptake of nutrients (derived from digested food) into the bloodstream and lymphatic system from the digestive tract.
The primary location where absorption takes place is within the small intestine, which is lined with countless tiny finger-like structures called villi. These villi play a crucial role in significantly augmenting the surface area of the intestine, thereby enhancing the efficiency and speed of absorption.
The absorption of a substance through the skin or a mucous membrane.
