AP Biology Lab 10: Physiology of the Circulatory System

Mr. Andersen introduces AP Biology Lab 10, focusing on the physiology of the circulatory system. The lab has two parts: measuring human blood pressure and observing how temperature affects the respiration rate of a goldfish. Blood pressure is measured using a sphygmomanometer and stethoscope, identifying systolic and diastolic pressures through Korotkoff sounds. The goldfish experiment involves changing water temperature and observing the operculum movements to determine respiration rate, highlighting the impact of temperature on ectotherms.

What are the two main activities conducted in the AP Biology Lab 10?

Explain how blood pressure is measured using a sphygmomanometer.

What are Korotkoff sounds and what do they indicate during blood pressure measurement?

How does the physiology of ectotherms differ from that of humans in terms of temperature regulation?

Describe the relationship between temperature and respiration rate in goldfish.
