How – and why – do snakes regulate blood flow?

PhD defense, Friday 27 January 2017. Renato Filogonio.

From a physiological perspective, reptiles are captivating organisms because of their fascinating cardiovascular design that allows oxygen rich and oxygen poor blood to mix inside the heart. Though this is hazardous as for warm blooded, metabolically demanding organisms like humans, reptiles have been suggested to benefit from this seemingly inneficient anatomical design or, at the very least, seem not to care about it! Using snakes as study organisms, Renato Filogonio investigated how the vascular system is controlled in reptiles, and how it relates to different oxygen demands.

It has been shown that the nervous system tightly controls the vascular system and the patterns of blood flow. This indicates that the vascular system of reptiles is indeed well adapted to provide adaptive advantages to this group.

The PhD degree was completed at the Section for Zoophysiology, Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
