Frog Dissection

Click here to watch a video of a frog dissection. How do the organs or the frog compare to that of the human? How are they different?

Antibody Animation

This 3D medical animation shows how antibodies stop harmful pathogens from attaching themselves to healthy cells in the blood stream. The animation begins by showing normal red and white blood cells flowing through the blood stream. A single pathogen appears onscreen slowly moving toward its destination on the surface of a cell. The tubular extensions on the pathogen are surface proteins which attach to corresponding surface proteins on a white blood cell, or leukocyte. As the animation continues, more pathogens continue to attach to the white blood cell, rendering it ineffective.

During the immune system response, Y-shaped antibodies begin attacking the pathogen, binding to its surface proteins as the pathogen attempts to anchor to the blood cell. The antibodies completely block the pathogen from attaching to the blood cell, "tagging" the pathogen so that one of the immune system's leaner cells, a macrophage, appears onscreen to engulf and digest the pathogen.

Allergies

Allergies are part of your body's non-specific immune system. Watch this animation to learn more.

What types of allergies do you suffer from?

Vaccines

Vaccines are used to expose the immune system to harmful antigens and teach the body how to fight back. After fighting off the vaccine, the body retains a lasting memory of how to fight off that particular type of attack. Watch the animation to learn more.

Click here for a detailed animation of how the nervous system processes information.  Be patient, the animation moves rather slowly, but there is a great deal of useful information about how messages are carried throughout the body, specifically through nerve cells. 

How does diffusion play a part in the transmission of nerve impulses?
