Describe the functional events in the negative feedback control of low blood volume and low blood pressure by the renin – angiotensin – aldosterone (RAA) system. Include potential causes, and the cascade of enzymes, prohormones and hormones, along with their sources.
Describe the structure and basic functions of juxtamedullary nephrons.
Describe the oxyhemoglobin saturation curve and how hemoglobin dissociation increases with exercise. How does pH, temperature, the partial pressure of CO₂ and 2,3-DPG affect the dissociation curves?

Negative and positive feedback mechanisms used to maintain homeostasis. Describe one negative and one positive feedback regulation (8pts). For each negative and positive feedback: What is the variable? (0.5pt) What is the normal range? (0.5 pt) Which conditions may change the variable? (0.5 pt) How the changes to be detected? (1 pt) What is/are the responses(s)? (1pt) What is the final effect? (0.5 pt)

Draw a negative feedback loop that corresponds to a drop in blood pressure. In a paragraph or two, explain how changes in blood pressure are regulated by the body. Include an explanation of how the RAA system functions to help regulate blood pressure.

Which of the answer choices is an example of negative feedback altering homeostatic control? A person with a bacterial infection runs a fever and his body temperatures rises and stays elevated for several days. The concentration of salt in a person's urine increases after that person eats a large bag of salty chips. A person's heart rate remains elevated over the course of a long run. The production of oxytocin (a hormone) increases in a pregnant woman's body as oxytocin...

Be able to describe the how a positive and negative feedback loop differ in regulating a body’s function. Then using a specific set of hormones, you learned about (you select which ones…a pair) describe how they work in a negative feedback loop. Include in your description where they are released from, what triggers each one of them to be released, what actions they have and if they have specific target tissues or are generally dispersed throughout the body. Finally, how...
