Hey!
Diffusion is an essential function in living organisms. Diffusion is the random but directional movement of molecules from a place of high concentration to a place of low concentration. This simple concept describes the process by which cells exchange toxic gases for life-sustaining gases. It also describes how nerve cells are able to send electrical signals to each other cells. Diffusion tells embryonic cells where to crawl and when they have arrived. Diffusion also makes it possible to reduce the loss of body heat to the surrounding environment.
The lungs have tiny empty grape-like sacs that are the hub of gas exchange. The cells of the body are constantly making energy molecules to sustain their daily activities. Not only does this process, called cellular respiration, require oxygen gas in order to work, it produces carbon dioxide gas, which is toxic to cells. The carbon dioxide produced by cells throughout the body is carried in the blood to the lungs. In the lungs, the carbon dioxide diffuses out of the blood and into the grape-like sacs. Oxygen gas that was breathed into the lungs goes in the opposite direction. Oxygen enters the blood. This vital exchange of gases happens by diffusion across thin layers of cells in the blood vessels that surround the grape-like sacs.
Nerve cells called neurons communicate with other cells by sending electrical signals along their cell membrane. At rest, the inside of the neuron’s membrane is negatively charged, while the outside is positively charged. An electrical signal is generated when the membrane lets ions from outside flow into the cell. This inflow changes the charge on the inside of the membrane from negative to positive. This switch in charge is an electrical signal that moves down the length of a neuron’s arm. The movement of ions that generates the electricity is diffusion.
