Xena is so hungry, and she is eating all her green root vegetables making her blood quite alkaline for a short time. In a healthy body, sometimes the O2/Hb curve shifts to the right (the green line in the figure above). Give one example of a change to blood chemistry that may shift the curve to the right in a healthy body. Explain what impact this has on O2 delivery to the tissues and explain the importance of this phenomenon in maintaining homeostasis.
