2) Ivan Urtleg took a well deserved trip to Tahiti withhis family after a long semester. While there, he discovered thatthe resort offered a \"Snorkel With Sharks\" activity. In a moment ofpoor decision making, he thought that it would be fun to swim withsharks. While swimming with the large predators, he decided toantagonize one by sticking his tongue out and goading it into afight. The shark immediately bit his right leg in the superiormedial region. As a result, two large blood vessels were severedand Mr. Urtleg began to bleed profusely. Thankfully, he stayed calmand made it back to the boat where he made and applied a tourniquetfashioned from a length of anchor rope and snorkel tube. On the wayto the ER, Ivan complained of intense thirst.

Explain how Ivan’s blood osmolarity, blood volume, andblood pressure have changed (or not changed) due to his extremeblood loss (3 pts) Which hormone pathways will be triggered bythese changes (Note this should only include pathways directlytriggered by the changes in blood, NOT pathways triggered by otherhormones) (2 pts)? How do these pathways cause the symptom ofintense thirst and why would drinking fluid help Ivan (what effectsdoes drinking water have in the blood) (4 pts)? What other ways dothese hormones try to account for massive blood loss (what effectsdo they have and how do these impact blood volume, pressure, and/orosmolarity) (9 pts)? Note that nowhere in this question do we askfor you to brain dump an entire hormone step by step pathways...weare asking about specific effects of the pathways! 2 pts for essayformatting, grammar, spelling.
