- Mr. Gregory comes to the doctor with high blood pressure. Tests show that he also has elevated levels of renin in his blood and atherosclerotic plaques that have nearly blocked blood flow through his renal arteries. Mr. Gregory is puzzled. Explain to him how decreased blood flow in his renal arteries could cause. renin secretion to increase. Map the pathways through which elevated renin causes high blood pressure for Mr. Gregory.4. The graph in Figure 4 shows changes in blood glucose concentration after a meal.

Clearly identify each stage.After you eat lunch nerve cells in your stomach respond to the distension resulting from the food. They relay this information to
- Perspiration, known more commonly as sweating, is an autonomic bodily response that decreases body temperature. During perspiration, the skin will secrete sweat that will ther- moregulate body tissues in certain conditions. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. In addition, the blood vessels will increase in diameter via a process called vasodilation, which will bring them closer to the skin and allow heat to more easily dissipate from the body. 3 increased blood temperature identified by central receptors vasodilation of peripheral vessels and skin arterioles to transfer more heat to the skin surface 5 A diagram of thermoregulation in the human body. 2 hypothalamus receives input and activates SNS response heat leaves the body and blood temperature lowers Respond to each part in 2 to 3 complete sentences. activation of sweat glands to begin sweating (a) Identify the type of feedback loop presented in the diagram. Justify your…Write a note on negative feedback mechanism and positive feedback back mechanism with two examples of each in the form of flow chart?The diagram in Figure 5 shows the difference between negative feedback and positive feedback. (i)Explain why negative feedback is important in homeostasis. (ii)Explain how negative feedback enables the carotid and aortic bodies and the medulla to maintain a constant blood carbon dioxide level. (iii)It is said that the initiation of an Action Potential is an example of positive feedback. With reference to the process involved, state why you think this statement is accurate?

Regulation of blood clotting Regulation of calcium concentration Regulation of electrolyte concentration Regulation of blood glucose concentrationIdentify the four components of a negative feedbackloop and explain what would happen if secretion of a bodychemical controlled by a negative feedback system becametoo great.when a person receive intravenous fluid to help up blood volume , why is it important to for the fluid to be isotonic?
- Which of the following most likely describes the relationship between protein and decreased blood pressure? O increasing arginine to stimulate nitric oxide O reabsorbing sodium O excreting chloride O providing all the essential amino acidsRead the following scenario and determine the parts of the homeostasis feedback loop. When a human increases physical activity, the amount of fuel burned in its cells also increases, which in turn increases the concentration of dissolved CO2 in the blood. The CO2 reacts with water in the blood to make a weak acid, which lowers the pH of the blood. Sensory cells in the aortic arch register this drop in pH and send sensory information to the medulla oblongata of the brain. The medulla oblongata sends signals to the diaphragm to increase respiration. This will clear the CO2 from the bloodstream. A. Name the stimulus in this scenario. B. Explain what a receptor is in the homeostasis feedback loop and name the receptor in this scenario. C. Explain what an integrating center is in the homeostasis feedback loop and name integrating center in this scenario. D. Explain what an effector is in the homeostasis feedback loop and name the effector in this scenario. E. Name the response in this…One of your patients is diagnosed with nephrotic syndrome in which too much protein is released in the urine.
