Mammalian Diving Reflex

Cardiovascular System Functions: Supply needed materials Remove Wastes Prevent disease Example: Blood carries oxygen from your lungs to your other body cells

The Heart

Metabolism Metabolism: the processes that keep you alive Why do your cells need oxygen?

Metabolism Supply vs. Demand Supply: How much is available Demand: How much you need

Apnea Apnea: temporary stop in breathing When does apnea happen?

Response to Apnea Supply of oxygen is limited Reduce metabolic demands 1. Lower heart rate 2. Restrict blood flow “Mammalian Diving Reflex”
