Question
Chapter 27, Problem 4RAC
Summary Introduction
Introduction:
The extracellular fluid volume can increase or decrease is in order to maintain a narrow range of value. The changes are regulated by the sensory receptor by detecting the change in the blood pressure.

Which of the following is a physiologic response of the kidneys to decreased
plasma volume?
decreased sodium reabsorption
O increased antinatriuretic protein secretion
dilatation of the afferent renal arterioles
increased tubular permeability to water
If plasma osmolarity is the independent variable and vasopressin release is the dependent variable, which graph would best describe their relationship? Please thoroughly explain the effect on the dependent variable if the independent variable increases so I can fully understand the concept.
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.

Extremely rapid weight loss may cause this tissue to shrink so that the kidneys slip from their normal position. On rare occasions, the slippage can put a kink in one or both ureters and block urine flow. Suggest what might then happen to the kidneys.arrow_forwardWhich of these conditions decreases extracellular fluid volume?a. constriction of afferent arteriolesb. increased ADH secretionc. decreased ANH secretiond. decreased aldosterone secretione. stimulation of sympathetic nerves to the kidneysarrow_forward
- In the proximal tubule, the reabsorption of Na+, amino acids, and glucose causes (before water moves): Decreased osmolarity of the tubular fluid but increased osmolarity of the interstitial fluid Decreased osmolarity of the tubular fluid and interstitial fluid O Increased osmolarity of the tubular fluid but decreased osmolarity of the interstitial fluid O Increased osmolarity of the tubular fluid and the interstitial fluid No changes in osmolarityarrow_forwardare both statements correct? In the absence of ADH, the kidneys produce dilute urine; renal tubules absorb more solutes than water. In the presence of ADH, the kidneys produce concentrated urine; large amounts of water are reabsorbed from the tubular fluid into interstitial fluid, increasing solute concentration of the urinearrow_forwardRenin is secreted in response to hypovolemia or to an increase in the osmolality of the blood. Provide three possible mechanisms by which these conditions may stimulate rennin secretion. What are the consequences of increased rennin secretion that lead to increased aldosterone secretion?
