The animal circulatory system transports oxygen and other nutrients to all cells and carries carbon dioxide and other waste products away. Various factors can affect the rate of circulation.

In this laboratory, you will:

1. Learn to take pulse and blood pressure in a human subject and gather data for a fitness index
2. Measure the effect of temperature on the heart rate of a small invertebrate, Daphnia magna
