Stimulated Diving And Heart Rate Lab Report
Laboratory 10 & 11: Stimulated Diving and Heart Rate Prelab Questions:
1.) If the peripheral blood vessels were constricted without making any other further adjustments in the cardiovascular system then the blood vessels could potentially burst due to the built up pressure and no further decrease in heart rate. The vessels would be smaller due to the constriction but the heart would continue to pump the blood with the same or greater force. The dive response prevents this from happening because it lowers the heart rate so that a lesser quantity of blood is pumped out through the constricted arteries. 2.) Order of animals based on how well developed the dive response should be, with reasoning:
1.)Tadpole-should not have an exaggerated
