Question #06: Basic functions of Renal, CV and Respiratory Systems The question for this week is as follows: Name the physiological responses and/or the relationships among buffers, respiratory, circulatory and renal systems involved in the homeostatic control following a metabolic acidosis. It is an absolute requirement that you answer this question based on the outline below. Precede each section of your answer with its heading, and make sure you answer ALL aspects outlined in each section. Hint: for this question you really have to think on âthe circleâ. The following are the section headings and their requirements: a) the example: which are the physiological responses and/or relationships among buffers, respiratory, circulatory and renal systems on which your answer will be based. Which was the origin of the metabolic acidosis in your example. Be as specific as you can in delimiting the boundaries of your example and the level(s) of organization your example will involve. b) the buffer involvement: how does the buffer system attempt to control the homeostatic variable (blood pH). Which, how and where is the signal to the buffer system recognized as input (receptors, afferent loop, and integration center), and how did the output of the integration center reached their targets (efferent loop, targets). The response this signal elicits is an acute (fast) or chronic (slow) compensatory mechanism. c) the respiratory involvement: how does the respiratory system attempt to control the homeostatic variable (blood pH). Which, how and where is the signal to the respiratory system recognized as input (receptors, afferent loop, and integration center), and how did the output of the integration center reached their targets (efferent loop, targets). The response this signal elicits is an acute (fast) or chronic (slow) compensatory mechanism. d) the circulatory involvement: how does the circulatory system attempt to control the homeostatic variable (blood pH). Which, how and where is the signal to the cardiovascular system recognized as input (receptors, afferent loop, and integration center), and how did the output of the integration center reached the targets (efferent loop, targets). The response this signal elicits is an acute (fast) or chronic (slow) compensatory mechanism. e) the renal involvement: how does the renal system attempt to control the homeostatic variable (blood pH). Which, how and where is the signal to the renal system recognized as input (receptors, afferent loop, and integration center), and how did the output of the integration center reached the targets (efferent loop, targets). The response this signal elicits is an acute (fast) or chronic (slow) compensatory mechanism. f) the integration pathways: how (the sensor, afferent, integrator, efferent, effector and feedback signals) and in which order (buffers, respiratory, cardiovascular, kidney) were the physiological systems involved, and recruited to participate in the homeostatic response to a metabolic acidosis. The most important component of this answer is: Why do you think such a sequential order in this homeostatic response was achieved? Please notice that this subquestion does NOT ask you to tell me what is the order, but it asks why that order occurred.

a) Name the structure and the function on which your overall answer will be based? Be as specific as you can in delimiting the boundaries of your example (the most important part of your answer, since the following b, c, & d sub-questions are based on your answer to this first sub-question, a). Please notice that only 1 item is required (in your answer it should be labeled as âaâ). This answer should look like: âa.- My structure (S) is â¦. and its function (F) is â¦â. In same cases a second sentence might be needed. b) Why do you think that your structure and your function are related? Support your contention based on 3 lines of evidence based on the chemistry, physics, anatomy, or physiology involved in your example. Please notice that 3 items are required (answers should be labeled as âb1, b2, and b3â). One of this answers might look like: âb1.- If I do this experiment and measure this variable using this technique, this result will suggest that my S/F is correctâ. Please notice that MY question does not ask you to tell me what happens since this can be copy from any source, but it asked how do you know that your S/F relationship is true. c) Which are the levels of organization involved in your example (c1)? Cite events occurring at its main level of organization (c2) and indicate how they relate to the whole body level (c3). Please notice that 3 items are required (thus, answers should be labeled as âc1, c2, and c3â). These answers should look as follows: âc1.- molecularâ or any level of organization involved in your âaâ answer (S/F); âc2.- the first event is; the next even is; the middle event is; the next event is; the last event isâ. Five events distributed equidistant from each other is a good summary for the story line of the your S/F named in your âaâ answer. Finally, âc3.- at a whole individual level my S/F described in âaâ plays this roleâ. d) Which are the main feedback mechanisms involved in your example (cite at least two) (d1)? Expand on one of them (d2) and name 2 absolute requirement for that feedback to work (d3). Please notice that 3 items are required (answers should be labeled as âd1, d2, and d3â). These answers should look as follows: âd1.- an increase in this negative feedback ligand must decrease this variable under controlâ. This is how you NAME a negative feedback. For d1 you need to name two negative feedbacks; âd2.- the first event is; the next even is; the middle event is; the next event is; the last event isâ. Five events distributed equidistant from each other is a good summary for the most important negative feedback story line involved as a control of the your S/F named in your âaâ answer, that you named in d1; âd3.- this two components are absolutely necessary for the negative feedback described in d2 to be operational.

True of False: Freshwater environments have a higher concentration of oxygen than saltwater environments.

QUESTION 2 If the difference in partial pressure of gas on either side of the barrier to diffusion is 0, which of these events will occur?

a decrease in the surface area of the capillary

QUESTION 6 Which of the following promotes oxygen release from hemoglobin?

a decrease in temperature

a decrease in carbon dioxide levels

a decrease in pH

QUESTION 7 How does the medulla oblongata sense the amount of carbon dioxide in the blood?

A. Carbonic anhydrase produced by cells performing cellular respiration is exported and travels though the blood, and binds to a receptor on the medullary respiratory center, which causes a signal amplification resulting in a change in gene expression which results in the production of proteins that will cause the diaphragm to contract

B. CO2 produced by cells performing cellular respiration reacts with blood plasma for form an acid, which increases the pH of the blood, which causes the medullary respiratory center to contract the diaphragm

C. CO2 produced by cells performing cellular respiration reacts with blood plasma for form an acid, which decreases the pH of the blood, which causes the medullary respiratory center to contract the diaphragm

D. A and B

E. A and C

QUESTION 10 How does the interstitial fluid return to the bloodstream?

A. Interstitial fluid flows into the capillary where the osmotic pressure driving fluid into the bloodstream is greater than the blood pressure driving fluid out of the blood

B. Interstitial fluid flows into the capillary where the blood pressure driving fluid into the bloodstream is greater than the osmotic pressure driving fluid out of the blood

C. Interstitial fluid leaves the tissue via lymphatic ducts and travels through the lymphatic system, which returns the fluid to the veins. D. A and C

E. B and C
