What you mean by absorption?

Absorption is a chemical or physical phenomenon in which the molecules, atoms and ions of the substance getting absorbed enters into the bulk phase (gas, liquid or solid) of the material in which it is taken up. Absorption is the condition in which something gets mixed or absorbed completely in another substance.

What is absorption in biology?

Absorption is the movement of digested food molecules through the wall of the intestine into the blood or lymph . The small intestine is the region where digested food is absorbed. ... The small intestine has a large internal surface area for absorption to happen quickly and efficiently.

What does absorption mean in digestion?

Absorption. The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.

What does absorption mean in chemistry?

Updated on July 03, 2019. Definition: Absorption is the process by which atoms, molecules, or ions enter a bulk phase (liquid, gas, solid). Absorption differs from from adsorption, since the atoms/molecules/ions are taken up by the volume, not by surface. Examples: absorption of carbon dioxide by sodium hydroxide.

What is absorption pharmacokinetics?

The most important principle in pharmacokinetics theory is drug absorption which is defined as the transportation of the unmetabolized drug from the site of administration to the body circulation system. ... The bioavailability of a drug product is known as the rate and extent of its absorption.

What is drug absorption?

Drug absorption is the movement of a drug into the bloodstream after administration. (See also Introduction to Administration and Kinetics of Drugs.

What does absorption mean in physics?

absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it. ... If there is only a small fractional absorption of energy, the medium is said to be transparent to that particular radiation, but, if all the energy is lost, the medium is said to be opaque.

What is absorption in digestion Class 10?

What is absorption? The process by which digested food molecules are absorbed into the bloodstream and transported to different parts of the body is known as absorption. 2.

What is absorption in digestion Class 7?

Absorption is the process by which digested food passes through the blood vessels in the wall of intestine. The inner wall of small intestine has finger like projections called villi which increases the surface area for absorption of food.

What is the difference between absorption and adsorption?

The main difference between absorption and adsorption is that absorption is the process in which a fluid dissolves by a liquid or a solid. ... In adsorption, the molecules are held loosely on the surface of the adsorbent and can be easily removed.

What is absorption in the small intestine?

Virtually all nutrients from the diet are absorbed into blood across the mucosa of the small intestine. In addition, the intestine absorbs water and electrolytes, thus playing a critical role in maintenance of body water and acid-base balance.

What is absorbed in large intestine?

The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.

What is the difference between absorption and bioavailability?

It is suggested that absorption be defined as movement of drug across the outer mucosal membranes of the GI tract, while bioavailability be defined as availability of drug to the general circulation or site of pharmacological actions.

Where are drugs absorbed?

For these reasons, most drugs are absorbed primarily in the small intestine, and acids, despite their ability as un-ionized drugs to readily cross membranes, are absorbed faster in the intestine than in the stomach (for review, see [1.

What is ionized and unionized drugs?

Most drugs are weak acids or bases that are present in solution as both the ionized and unionized forms. Ionized molecules are usually unable to penetrate lipid cell membranes because they are hydrophilic and poorly lipid soluble. Unionized molecules are usually lipid soluble and can diffuse across cell membranes.
