Action Potential Physiology (FULL VIDEO)

In this video, we will discuss the absorptive properties of the Loop of Henle's ascending and descending limbs and how the Loop of Henle's set-up drives countercurrent multiplication.

A&P I Lab | Exercise 3a: Diffusion, Osmosis, & Diffusion Rate

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...

Action Potential Physiology (Part 1)

Jaguar vs. Caiman - the ultimate showdown! On this episode, Coyote, Mario and Trent venture deep into the Brazilian Pantanal to capture up close footage of the region's king of big cats: the jaguar! For seven days the team essentially...

The video discusses the factors that affect the rate of chemical reactions. The first factor is the number of collisions with enough energy to react. Other factors include changing the pressure, concentration, surface area, and...

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...

Lactose Transporter How Does it Work

This video explains the difference between electrical conductors and insulators, and how insulators can be charged by friction. It goes into detail about the movement of electrons and how charges can be conserved. The video also...

This type of tissue is found in skeletal muscles and is responsible for the voluntary movements of bones.

Learn the basics about Diffusion of gases. How are gases diffused? What methods are used to diffuse gases? Find out more in this video!

In this video, we will discuss four factors that affect the rate of diffusion: molecular weight, concentration gradient, surface area-volume ratio, and the temperature.

Glucose Transporter (GLUT) How Does it Work

What is it that separates what's inside a cell from what's outside of a cell? Why, that's the cell membrane. What's it made out of? How does it work? How do molecules get in and out of the cell? These are super-important concepts! Let's...

In the first part of this video we looked at diffusion to move gases and osmosis for the movement of water, from high concentration to low concentration down their concentration gradient. Active transport works in the opposite...

In this video we are going to discover how cells take in useful substances and remove waste using three methods of transportation: diffusion, osmosis and then in the second part we will look at active transport. The exchange of materials...

This video explains the concept of active transport, comparing it to the movement of smoke from an area of low concentration to an area of high concentration. This video is part of the 14-part series, Cell Processes.

Small intestine and food absorption Digestion goes hand in hand with absorption… which happens in your small intestine. Which is what we’re going to look at in this video. So keep watching!
