What is the definition of 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.
What is the definition of absorption in the digestive system?
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 is absorption explain it?
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 simple words?
Absorption is a condition in which something takes in another substance. It is a physical or chemical phenomenon or process, in which atoms, molecules, or ions enter in the inner part (called “bulk”) of a gas, liquid, or solid material. This is a different process from adsorption.
What is absorption in pharmacy?
Absorption is the process of delivering a drug into the blood stream. Absorption can be accomplished by administering the drug in a variety of different ways (e.g. orally, rectally, intra-muscularly, subcutaneously, inhalation, topically, etc.).
What is the absorption answer?
Absorption is a process in which a substance is assimilated in another substance. The substance that gets absorbed is known as the absorbate and the bulk phase in which the absorption takes place is known as the absorbent. In this example, the paper towel is the absorbent and water is the absorbate.
What is absorption process?
The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface. The process of gas or liquid which penetrate into the body of adsorbent is commonly known as absorption.
What is absorb mean in science?
to receive or take in (the energy of an impact) physics to take in (all or part of incident radiated energy) and retain the part that is not reflected or transmitted.
Where is medication 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.
How is medicine absorbed?
The vast majority of medications are taken orally and are broken down within the gastrointestinal tract. Once the medication arrives, it is broken down by stomach acids before it passes through the liver and then enters the bloodstream.
What is absorption explain with example?
Absorption is defined as the process when one thing becomes part of another thing, or the process of something soaking, either literally or figuratively. An example of absorption is soaking up spilled milk with a paper towel. A paper towel takes up water, and water takes up carbon dioxide, by absorption.
What is absorption of a substance?
Physical or chemical absorption is a process in which atoms or molecules enter the bulk phase of a gas, liquid, or solid material and are taken up within the volume.
What does adsorption mean in chemistry?
Adsorption is defined as the adhesion of a chemical species onto the surface of particles. German physicist Heinrich Kayser coined the term “adsorption” in 1881.
What is an example of absorption in science?
Absorption is when a wave comes into contact with a medium and causes the medium’s molecules to vibrate and move. This vibration absorbs or takes some of the energy away from the wave and less of the energy is reflected. One example of absorption is black pavement which absorbs energy from light.
What is the absorption process?
An absorption process occurs when a chemical is removed from one gas or liquid stream by mixing it with another stream. This process can be used in chemical processing, refrigeration to cool foods, human digestion of vitamins and minerals, and when plants take in nutrients.
What is the definition of absorption?
absorption – (chemistry) a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid. soaking up. chemical science, chemistry – the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions.
