Artic Ground Squirrels
1. Describe I/R injury in your own words
I/R injury is when tissue is damaged due to lack of oxygen.
2. Describe mammalian hibernation, making sure to include specifics on body temperature drops, metabolic rates, and respiratory rates.
Mammalian hibernation is a process the body undergoes when trying to protect against extreme weathers and to help conserve energy for a few weeks or an extended period of time while a food source is scarce. Hibernation is a state where metabolic rate is low or inactive, low heart rate and, slowed breath. Those animals that have small body weights drop drastically in body temps while larger mammals have a smaller change and do not drop as low as an artic ground squirrel can.

This gives the researches a broader view of animals that do not go through what the artic ground squirrel do.
7a. What is troponin?
Troponin is a globular protein that assists in muscle contraction.
7b. What do levels of troponin in the blood suggest?
If there are high levels of troponin suggest that the heart has been damaged. When the heart is damaged this proteins are released into the blood.
8a. In figure 2A, are the results what you would expect to see comparing the arctic ground squirrel (ASG), the Brown Norway rat (RAT (BN)), and the Dahl rat (RAT (SS))? Discuss the results in your own words!
The results are what I would have expected to see comparing the artic ground squirrel, and Brown Norway rat and Dahl rats. The graph shows that rodent with the least amount of heart damage is the artic ground squirrel that hibernates during the winter and that the Dahl Salt sensitive rat has the most levels of troponin in the blood levels meaning that the Dahl Salt sensitive rate had the highest about of heart damage. The artic squirrel is able to provide the most protection for their
