Ch. 26 Renal Filtration – Flashcards

Mike's injury is going to impact his urinary system significantly. Which of the following is NOT a function of the urinary system?

Mike's injury caused his ureter to be torn away at the hilum of the kidney. What internal kidney structures funnel the urine into the renal pelvis of the ureter?

The first step in the formation of urine is the generation of filtrate from the blood plasma by filtration. In what part of the nephron does the formation of filtrate occur?

There are multiple pressures involved in controlling glomerular filtration and the formation of filtrate. Which is the pressure that opposes the formation of filtrate by drawing water out of the filtrate and back into the plasma?

Which of these is NOT a property of countercurrent multiplication?

Which statement best describes the relationship between Type 2 diabetes and the transport maximum (Tm)?

The step in kidney function in which fluid is forced out of the blood includes moving fluid __________.

During filtration, anything that is small enough to pass through all three layers of the filtration membrane will become part of the filtrate. Sometimes, the least porous layer of this membrane becomes clogged and then glomerulonephritis may occur. What is the name of the most porous layer of the filtration membrane?

What triggers the movement of water out of the descending limb?

Antidiuretic hormone (ADH) causes __________.

One of the organic substances not normally excreted by the kidney is __________.

All of the following processes are functions of the urinary system EXCEPT __________.

Which of the following statements about aldosterone is NOT correct?

Which of the following statements about ADH (antidiuretic hormone) is correct?

What is the osmolarity of the filtrate at the end of the proximal tubule?

In overhydration, what would be the levels of ADH (high, normal, or low) and what would be the osmolarity of the urine?

In severe dehydration or blood loss, what would be the levels of ADH and what would be the urine flow rate?

Sheila has been exercising at peak performance for about 60 minutes. She did not hydrate as effectively as she should have and as a result, her urine is deep yellow and low in volume. Which of the following is the most likely mechanism affecting this?

The main site for water reabsorption along the nephron is the __________.

Which of these hormones causes the kidney to increase the body's content of sodium?

A diuretic drug called thiazide increases water loss by reducing ion reabsorption in the proximal and the distal convoluted tubules. Which of the following answer choices correctly pertains to this statement?

The main force(s) opposing glomerular filtration is (are) __________.

A decrease in blood albumin level will cause a decrease in blood colloid osmotic pressure. This will lead to a rise in the net glomerular filtration pressure. Are these two statements true or false?

Besides being very painful, a blockage in a ureter due to kidney stones or external pressure is serious because it leads to an increase in capsular hydrostatic pressure. What is the consequence of this increase in pressure?

Chronic and acute renal failure impairs all of the functions carried out by the kidneys and, as a consequence, the functions of most other body systems. Which of the following renal functions is matched incorrectly?

Some patients with kidney failure regularly undergo a procedure called hemodialysis to cleanse their blood. This procedure thus effectively replaces which of the following kidney components.

Which of the choices below best describes the glomerular filtration rate (GFR)?

Which of the following best describes the passive force that creates filtrate?

What is the primary regulatory mechanism that maintains glomerular filtration rate (GFR)?

Which of the following GFR-regulating mechanisms is initiated by cells of the juxtaglomerular complex?

The myogenic mechanism of renal autoregulation primarily involves smooth muscle in which blood vessels?

In the event of a severe increase in systemic blood pressure, what mechanism would increase GFR?

What enzyme is released by the juxtaglomerular complex to regulate GFR?

Which of the choices below best describes the autonomic mechanism for regulating GFR?
