Jul 15, 2021 · Absorption Definition and Examples. Absorption occurs when ions, atoms, or molecules pass into a bulky material. These particles (the absorbate) diffuse or dissolve into the absorbent substance. A familiar example is a paper towel picking up water. Eventually, water evenly permeates the paper.
Table of Contents. Absorption can be defined as the process of assimilating substances across the intestinal epithelial cells or the tissues and organs through the process of active or passive transport. This can be facilitated through diffusion or osmosis and always follows the digestion process and never precedes it.

Keywords. Digestion - Digestion is the process of breaking down large food molecules into smaller molecules that can be absorbed into the blood. Enzyme - An enzyme is a biological molecule that is a catalyst that speeds up the rate of a reaction. Carbohydrate - A carbohydrate is a molecule made of carbon, hydrogen and oxygen, and provides energy.
Keywords. Blood - Blood is a liquid which transports nutrients and waste around the body. Absorption - Absorption is the process of moving nutrients from the digestive system into the blood. Surface area - Surface area is the area of a surface. Diffusion - Diffusion is the net movement of particles from an area of higher concentration to an ...
An example of this is the absorption of water into a sponge. Chemical Absorption: In this type of absorption, the absorbed substance is chemically bonded to the absorbing material. An example of this is the absorption of carbon dioxide by a strong base to form a carbonate compound.

May 11, 2018 · docx, 621.12 KB. This resource is for KS3 Science (Biology). It is intended to ask students to summarise the digestion and absorption of food. The power point pictures are given letters and students must number them in order to sequence the processes. They can also briefly describe each process.
