25
If you looked closely at the tip of a renal papilla with a hand lens, the hundreds of little openings you would see on its surface are
openings of papillary ducts.
26
An increase in the permeability of collecting tubule cells to water is due to
an increase in the production of antidiuretic hormone.
27
85% of nephrons are described by this term that relates to their location in the kidney.
cortical
28
Cortical nephrons are different from juxtamedullary nephrons in that
their nephron loop is shorter, with a shorter thin segment.
29
Which of the following is found exclusively in the renal medulla?
nephron loop of juxtamedullary nephrons
30
In the juxtaglomerular apparatus, the macula densa is part of the
terminal nephron loop.
31
The region of the distal tubule that monitors concentration of the filtrate is called the
macula densa
32
Arteries that branch to form the afferent arterioles to the glomeruli are
cortical radiate arteries.
33
How much of the fluid filtered by the kidney actually becomes urine?
1%
34
Ladderlike looping blood vessels within the medulla.
vasa recta
35
An important difference between the peritubular capillaries and the vasa recta in the kidney is that
the vasa recta are in the medulla, whereas the peritubular capillaries are in the cortex.
36
Blood vessel that contains granular cells involved in blood pressure regulation.
afferent arteriole
37
Renin is produced in
the granular cells.
38
Urine passes through the
renal pelvis to the ureter to the bladder to the urethra.
39
The ureters
have a muscularis layer that is stimulated to contract by the stretching of their walls as urine enters them.
40
Which of the following statements about the urinary bladder is false?
In females, the bladder lies posterior to the uterus but anterior to the rectum.
41
The neck, or inferior angle, of the bladder drains into the
urethra.
42
The epithelium lining the urinary bladder that permits distension is
transitional.
43
Contraction of this muscle forces urine from the bladder.
detrusor
44
The name of the inferior of the three openings in the trigone of the bladder is the
internal urethral orifice.
45
Of the following, the only epithelial type that does not line the urethra is
simple squamous.
46
Which of the following statements about the internal urethral sphincter is false?
It is surrounded by the urogenital diaphragm.
47
Which of the following would not inhibit micturition?
relaxation of the internal urethral sphincter
48
In the micturition reflex, the detrusor muscle is stimulated to contract by
parasympathetic fibers.
49
What anatomical difference makes urinary tract infections more common in females than in males?
In females the urethra is shorter than in males.
50
The ________ attaches the liver to the lesser curvature of the stomach.
lesser omentum
51
Attaches the liver to the anterior abdominal wall and diaphragm.
falciform ligament
52
Another name for the serosa covering many organs of the digestive system is
visceral peritoneum.
53
Which of the following correctly describes a function of the greater omentum?
It stores fat.
54
Which of the following is not an accessory digestive organ?
spleen
55
Which of the following is a secondarily retroperitoneal organ?
descending colon
56
Of the basic digestive processes, the one in which nutrients enter capillaries is called
absorption.
57
Layer of the GI tract responsible for segmentation.

20
64
Why are bacteria abundant in the large intestines but not in the stomach?

66
The largest salivary gland is the
parotid
67
Which of the following statements about the large intestine is false?
It is longer than the small intestine.

In mastication, the relative roles of an incisor versus a molar are
biting off pieces of food versus grinding.
72
Which of the following statements about the duodenum is false?
It is more movable than the ileum or jejunum, which are retroperitoneal.
73
Which of the following layers is present in the mucosa of the stomach and intestines, but not in the mucosa of the mouth and pharynx?
muscularis mucosae
74
Which of the following is not a characteristic of enteroendocrine cells?
They are scattered throughout the lining of the rectum.
75
The splenic flexure is the boundary between the
ileum
76
The correct sequence of layers in the wall of the alimentary canal, from internal to external, is
mucosa, submucosa, muscularis, serosa.
77
In the stomach, the undifferentiated epithelial stem cells lie near the junction of the gastric pits and gastric glands. In the intestine, the corresponding stem cells occur
deep within the intestinal glands (crypts of Lieberkühn).
78
Disease of which structure is the most common cause of tooth loss in adults?
periodontal ligament
79
The parietal cells in the stomach produce
intrinsic factor and HCl.
80

storage of bile
