Diuretics are sometimes used to treat hypertension. Explain what a diuretic is, and how
it can help reduce blood pressure.
Patients with kidney disease lose plasma albumin in their urine. This loss of plasma proteins may lead to edema in these patients’ tissues. Use what you know about capillary filtration and reabsorption to explain why this edema occurs. The answer must include an explanation of what edema is.
Compare and contrast the functions of the kidneys and the heart using a table. If both were candidates running for the presidential elections inside your body, which one would choose and why? If you do not want to vote for either the heart or the kidney, which organ would you vote for and why? Think of a way to make your reason more substantial by considering the role of both the heart and the kidneys in blood pressure regulation.

- When blood pressure increases, the baroreceptor reflex is activated, and also kidney response pathways are activated. Which pathway acts faster to achieve a decrease in blood pressure, baroreceptor or kidney? Explain your answerarrow_forwardHypertension is a major health issue in the United States, yet glomerular filtration rate is not autoregulated until mean arterial blood pressure exceeds 180 mm Hg. In contrast, a drop in mean arterial blood pressure of only a few mm Hg sets autoregulation into motion. What does this tell you about the regulation of blood pressure?arrow_forwardAlthough the kidneys are probably best known as filtration organs, they also help control blood pressure. Explain their role in this process. please help with examplesarrow_forward
- High blood pressure often is accompanied by kidney damage. In somepeople the kidney damage is subsequent to the high blood pressure, but in others the kidney damage is what caused the high blood pressure. How would a low-salt diet enable you to determine whether the high blood pressure or the kidney damage came first?arrow_forwardMr. Duderino comes to the doctor with high blood pressure. Test show that he also has elevated levels of renin in his blood and atherosclerotic plaques that have nearly blood blow 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.Gregoryarrow_forwardMr. 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.

- Some patients with hypertension are kept on a low-salt (low-sodium)diet. Propose an explanation for this therapy.arrow_forwardPressure sensing by the kidneys is a better surrogate for: A. Heart rate B. Stroke volume C. Cardiac output D. Differences in water concentration between the intracellular and extracellular compartmentsarrow_forwardDescribe how hormones regulate blood pressure, blood volume, and kidney function.arrow_forward
- A patient has essential hypertension, and with a healthy lifestyle and medication, he is able to maintain normal blood pressure on a single antihypertensive medication. The medication he takes is called an angiotensin converting enzyme inhibitor, or ACE inhibitor, which blocks the activation of angiotensin II. Describe at least two mechanisms by which angiotensin II targets the kidneys to increase extracellular fluid volume and, therefore, increase blood pressure.arrow_forwardWhen Jay had diarrhea his blood pressure dropped so his body took an action to compensate. Which one of the followings would better describe the mechanism Question 64 options: BP drop affects blood vessels baroreceptors and activates renin-angiotensin-aldosterone mechanism leading to increase ADH release BP drop affects blood vessels baroreceptors and activates renin-angiotensin-aldosterone mechanism leading to decrease ADH release BP drop affects blood vessels baroreceptors and inhibit renin-angiotensin-aldosterone mechanism leading to decrease ADH release BP drop affect blood vessels baroreceptors and inhibit renin-angiotensin-aldosterone mechanism leading to increase ADH releasearrow_forwardWhich hormone increases blood volume by increasing reabsorption of water in the kidneys?
