Outline and diagram the effects of Vasopressin (ADH) on the nephron, and how it promotes water conservation in the kidneys. Be sure to EXPLAIN the cellular mechanisms of action.

I want to reach out and grab my cup of coffee. Name and describe the three steps involved in accomplishing this task. What brain region(s) are most closely associated with Step 2? Provide evidence that details how Step 2 appears to be accomplished by the brain.

3. Carla (200 lbs) is a 27 year old female that decides to start a fitness program. She decides to walk on a treadmill at an average pace of 3.3 mph and an incline of 10%. Use the ACSM metabolic equation for walking.

1. Calculate the GROSS oxygen cost (ml/kg/min) (2 points)

2. How would you classify her CRF at this stage? Is this her VO2max? Why or why not? (2 points)

4. Greg Lemond-a world level professional cyclist- cycles on a Monark ergometer at a pedal cadence of 80 RPM and a resistance setting of 5 kg. He weighs 70 kg.

1. What is his power output/work rate (kpm/min)? (1 point)

2. Using the ACSM metabolic equation, calculate Lemond's predicted GROSS oxygen cost (ml/kg/min) for this work rate (2 points).

3. Convert this oxygen cost to METs (1 point)

5.) What is the predicted relative VO2 for a 225 lbs man cycling at a resistance of 98 watts (2 points

After Julien was stabilized and had been given antivenom, the attending physician came to talk to the Brahims. She explained that the mechanism of action for Chironex fleckeri, commonly known as the box jellyfish, is not well understood. However, based on what is known, it seems the toxin has multiple effects. One component of the toxin is thought to function as a calcium pore-forming protein that is inserted into the membrane of autorhythmic cells (and possibly other cells). Tanya thought back to her physiology course and remembered that intracellular calcium concentrations are much lower than extracellular concentrations. She knew that this ion plays a large role in cardiac cells and in muscles. When stung, Julien had felt lethargic and was having trouble breathing, and noticed something off with his heart rate. Tanya started to wonder about the pathophysiology of this venom. While she sat next to Julien she began running through various physiological scenarios in her head.

Question

11. Based on what the physician stated, how do you think this toxin would impact the action potentials and function of autorhythmic cells and the activity of the heart? State your hypothesis, and then draw a graph to accompany your predicted outcome.

1. Is it important that there is a genetic basis to weight and obesity?
2. Is obesity a disease?
3. Does labeling something as a “disease” or “disorder” or “genetic” change how we should view that person or condition?
