How the Circulatory System Delivers Oxygen: The Importance of the Heart and Lungs
The video explains the anatomy and physiology of the circulatory system and how the organs within it work together to deliver oxygen to cells and remove carbon dioxide. The video also goes into detail about the structure of the lungs and...

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....

The Consequences of Declining Human Capital
In part 2 of INET's interview with Giovanni Dosi, he talks about how decaying education standards are causing direct economic and psychic inequality -- and will ultimately erode the fabric of society

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...

Water and Diffusion - The Chemistry of Life
In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.
I also deal with diffusion and go into the 3 factors that affect...

Understanding Osmosis: Diffusion of Water Through a Partially Permeable Membrane.
The video is about osmosis, a type of diffusion in which water molecules move from a dilute solution to a concentrated solution through a partially permeable membrane. The video explains what a partially permeable membrane is and how it...

Gas Exchange In Different Animals
Respiration is carried out by all living things. Animals need oxygen to carry out aerobic respiration and they need to get rid of the waste product called carbon dioxide. This is called gas exchange. Swapping one gas for another. Animals...
