Document Summary
Biob32 lecture 4 can buffer the need for oxygen in the tissue. King penguin and the turtle have huge oxygen storage in the muscle and it. The oxygen that is going to sustain you is what you carry with you. Elephant seal evolved huge oxygen storage capacity so they don"t have the nitrogen. They all have high hematocrit, high blood volume. Can store blood in the spleen and can be released in the need of blood. Elephant seals can hold their breathe and have huge lungs. Weddell seal released all the air out of lungs before they jump into the water. See differences in mammals in the size of medulla or if there are long or short. They have very little liquid water intake and this intake is reliant on metabolic intake. So this means have to minimize their water loss. Loss through the urine is minimized by their ability to concentrate their urine significantly.
