How do decreases in PCO2, pH, temperature and organic phosphate modulators (i.e. 2,3-DPG) shift the oxygen equilibrium curve of animals? If the oxygen equilibrium curve shifts to the right, how does that change an animal’s P50? How does it change its oxygen affinity?

Breathing 100% oxygen will:

A. Increase p02 and the rate of oxygen unloading at the tissues.

B. Cause a right shift in the oxygen-hemoglobin dissociation curve.

C. Significantly increase oxyhemoglobin saturation.

2. All of the following play a role in increasing the oxygen unloading at tissue in someone with iron deficiency anemia except?

A. Respiratory acidosis

B. An increase in 2-3 DPG

Bae just knocked over a jewelry shop, making off with a couple of bars of 24K gold. On the lam from the cops, they run toward a river. Noting a patch with many reeds (hollow-centered plants), they cut a piece of reed approximately 2’ long. With the gold bars in their pockets, they submerge themselves 1&1/2 feet into the river and begin to breathe, confident they will escape the cops. Within seconds, they were captured, and their one phone call is to you for some bail money.

Why were they caught so soon? What changes in arterial blood gases would occur as a result?

Sketch what a davenport curve would look like at the moment of capture, showing what their acid-base status would be? Why?

Your grandmother has had several episodes of acid-reflux recently. In order to enjoy the gastronomical celebrations of your commencement (yay! By the way, she's the one that brought that ginormous boquet of balloons just for you...), they consume a heaping helping of Tums (which contain alkaline ingredients and are often taken as an antacid.)

1. What effect would consuming a heaping helping of Tums have on acid-base balance?

2. What effect would this have on their digestive processes? Please be specific about the processes and the locations affected. What symptom(s) (other than a stomach ache) would they exhibit?

• Distinguish between water-soluble (hydrophilic) and lipid-soluble (hydrophobic) hormones. List examples of each. Describe how each are secreted from cells, travel via the circulatory system, receptor location on target cells, and mechanism(s) for eliciting cellular responses.

• What are endocrine glands? List several examples. (Contrast these with exocrine glands. You learned about several of these when you studied digestion.) Note that many endocrine glands are also organs with other functions.
