The Visible Heart
This animation focuses on the gross anatomy of the human heart. The model of the heart is semitransparent, allowing you to see through the thick cardiac muscle into the four heart chambers.

The job of the human heart—in fact of all vertebrate hearts—is to pump oxygenated blood throughout the cells of the body and to return deoxygenated blood to lungs or gills for replenishment.

Heart Size in Mammals
Explore the relationship between heart size and rate in this multimedia demonstration by one of HHMI's high school interns from Thomas Edison High School of Technology in Montgomery County, Maryland.
Heart Size in Mammals (HHMI)
A quick tutorial on the basics of the electrocardiogram machine. Created by one of HHMI's high school interns from Thomas Edison High School of Technology in Montgomery County, Maryland.

The Vertebrate Circulatorium
In the Veterbrate Circulatorium you can compare the circulation patterns of different vertebrates. Click on the different animal names on the left to see the overall circulation patterns in "systemic view." More detailed views of the hearts are available by clicking on "To heart detail."

Vital Signs: Understanding Cardiovascular Diseases
This virtual exhibit has been adapted from the exhibit that complemented the 1998 Holiday Lectures on Science. Drs. Richard P. Lifton and Christine E. Seidman, both HHMI investigators exploring the genetic basis of disease, delivered the 1998 lectures, "Of Hearts and Hypertension: Blazing Genetic Trails." We hope you will find the experience of this virtual exhibit to be rich and compelling and that it will serve as a valuable resource to you for science research projects or as a source of background information about cardiovascular disease.
