Integrated physiology about Houdini
Explain in terms of integrated physiological functions how Houdini was able to modulate his normal physiology and be successful at his amazing stunts. Discuss ONLY the possible modifications. For example, as you know, some functions of the body are involuntary and not meant to be manipulated by the person will. Breath holding would normally result in an autonomic impulse to breathe, to return the body to homeostasis. What did Houdini need to do to overcome this natural response? Please discuss the modifications to each physiological system:
-Muscular
-Nervous
-Endocrine
-Cardiovasular
-Respiratory
-Digestive
-Urinary
-Skeletal
