 Module 8 Quiz    

•  Question 1 The glomerular filtration rate is about 120-125 mL/min in a healthy adult and increases drastically during kidney failure.

True

False

•  Question 2 In healthy kidneys, which of these substances is NOT a common substance filtered out of the glomerulus?

1.            Vitamin C

2.            Glucose

3.            Sodium ions

4.            Erythrocytes

•  Question 3 Which of the following statements is true about urine?

1.            It is mainly composed of glucose

2.            WBCs are commonly found in microscopic examination of normal urine sediment

3.            Urea is the highest solute concentration in urine

4.            Red blood cells and proteins are normally found in urine

•  Question 4 Aldosterone’s main effect is to the raise the blood pressure by increasing sodium ion absorption in the nephrons leading to increased water absorption and increased water volume.

True

False

•  Question 5 Diuretics are a class of drugs that increase the activity of antidiuretic hormone.

True

False

•  Question 6 Which of the following choices is the correct sequence of the nephron?

1.            Loop of Henle, Proximal Convoluted Tubule, Glomerulus, Distal Convoluted Tubule

2.            Glomerulus, Loop of Henle, Proximal Convoluted Tubule, Distal Convoluted Tubule

3.            Glomerulus, Proximal Convoluted Tubule, Loop of Henle, Distal Convoluted Tubule

4.            Proximal Convoluted Tubule, Loop of Henle, Distal Convoluted Tubule, Glomerulus

•  Question 7 Water can only be reabsorbed in the distal convoluted tubule portion of the nephron.

True

False

•  Question 8 The nephrons drain the filtrate into the minor and major calyxes that converge to form the renal pelvis.

True

False

•  Question 9 The kidneys secrete a hormone that influences red blood cell production.

True

False

•  Question 10 Which of the following is true of urine formation?

1.            Glomerular filtration depends on the blood flow from the vasa recta

2.            Items/substances in excess, such as excess vitamin C, will be reabsorbed by the renal tubules

3.            The glomerulus technically consists of three filtration membranes to prevent larger items such as proteins from being filtered out

4.            The nephron loop or Loop of Henle function is influenced by antidiuretic hormone

•  Question 11

Renal pyramids are found in the:

1.            Ureters

2.            Renal pelvis

3.            Renal medulla

4.            Renal cortex

•  Question 12 Which of the following statements is true regarding the renal blood vessels?

1.            The vasa recta vessels primarily surround the collecting duct

2.            The glomerulus is a group of blood vessels that surrounds the Loop of Henle

3.            The peritubular vessels surround the collecting duct only

4.            The afferent arteriole provides the blood flow into each glomerulus

•  Question 13 The blood vessels surrounding the Loop of Henle are called the:

1.Afferent arterioles

2.Efferent arterioles

3.Peritubular capillaries

4.Vasa recta

•  Question 14 Which of the following statements is true of the urinary bladder?

1.            The bladder is controlled by a single urethral sphincter

2.            It is located posteriorly to the naval (belly button)

3.            It has thick smooth muscle layer called the detrusor muscle

4.            Bladder infections are more likely in males than females

•  Question 15 The internal urethral sphincter is under conscious control.

 True

 False

•  Question 16 Tubular secretion occurs when:

1.            In the nephron loop only

2.            When the blood vessels secrete larger molecules, such as proteins, into the renal tubules

3.            Atrial natriuretic peptide hormone causes the glomerulus to secrete proteins into the Bowman’s capsule

4.            The renal tubules secrete proteins into the blood vessels

•  Question 17 Which of the following statements is true of hormonal control on the nephron?

1.            Atrial Natriuretic Peptide will decrease blood volume and blood pressure

2.            Aldosterone, Atrial Natriuretic Peptide, and Antidiuretic hormone will both lead to increase water absorption in the collecting duct

3.            Aldosterone increases sodium reabsorption in the distal convoluted tubule and collecting duct

4.            Antidiuretic hormone is secreted when there are high water levels in the body

•  Question 18

A healthy adult kidney filters roughly 2 liters of filtrate each day.

True

False

•  Question 19

The glomerular filtration rate (GFR) is highly regulated because if GFR increases, the amount of urine output decreases.

True

False

•  Question 20 Which of the following statements is true of a nephron?

1.            The collecting duct primarily reabsorbs the nutrient glucose

2.            The blood is filtered in the renal tubule section.

3.            Nephrons are the structural and functional units of the kidneys

4.            Nephrons are only found in the cortex of the kidneys

•  Question 21 The process of tubular reabsorption reabsorbs 99% of the filtrate produced.

True

False

•  Question 22 Which of the following statements is NOT true of the urethra?

1.            Incontinence can occur due to weaken pelvic muscles

2.            The female’s urethra is much shorter than a males and therefore doesn’t have an external urethral sphincter

3.            If there is urinary retention, then a catheter is inserted within an individual

4.            The male’s urethra passes through the prostate gland

•  Question 23 For micturition to occur, you have to consciously relax both the internal and external urethral sphincters.

True

False

•  Question 24 The Loop of Henle is a tuft of capillaries that are very porous.

True

False

•  Question 25 Substances, such as excess ions, can leave the body through a process called tubular secretion.

True

False
