Diffusion: How Substances Move In and Out of Cells
This video explains how substances move in and out of cells via diffusion, which is the net movement of particles from an area of high concentration to an area of low concentration. The video first defines diffusion and illustrates it...

HST-AP Introduction to the Respiratory System
The Respiratory System plays a major part in our survival and works hand in hand with the Circulatory System. Respiration for the body can not happen without the circulation of the blood driven by the cardiovascular system. Simply said,...

Exchange and transport systems in animals
Imagine if it took a couple of months for the oxygen we breathed to reach our cells. Well, if we relied on diffusion alone for oxygen to get to the tips of our toes, it would take about this long. By this time, our cells would have died....

Practice Problem: Graham's Law of Effusion
We know that molecules will travel at an average velocity that is inversely proportional to their molar mass. This means that lighter gases travel faster. We can relate the rates of effusion for two gases using Graham's law, and we can...
