Place these vessels in the correct order as blood flows into and through the kidney. 1. afferent arteriole 2. arcuate artery 3. efferent arteriole 4. glomerulus 5. interlobar artery 6. interlobular (cortical radiate) artery 7. renal artery 8. segmental artery
7,8,5,2,6,1,4,3
A glomerulus is:
a set of capillaries within the renal corpuscle
What external covering protects the kidney from physical shock?
adipose capsule
What is NOT a true statement about the cortical nephrons?
cortical nephrons are wrapped by the vasa recta
Simple squamous epithelium is located in the:
descending limb of the nephron loop (loop of Henle).
Filtrate traveling through the renal tubule travels from the thick ascending limb to the:
distal tubule
What increases the permeability of the glomerulus by making the capillaries "leaky"?
fenestration
Which of the following is the capillary bed fed by the afferent arteriole and drained by the efferent arteriole?
glomerular capillaries
What is NOT a major function of the kidneys?
hematopoiesis
The indentation on the medial surface of the kidney is the:
hilum
distal tubule
identify the circled structure
The right kidney sits ________ to the left kidney due to the position of the liver.
inferior
Where does blood in the arcuate artery travel next on its journey toward the glomerulus?
interlobular (cortical radiate) artery
The cells of the macula densa and the juxtaglomerular (JG) cells form the:
juxtaglomerular apparatus (JGA)
The functional units of the kidneys are:
nephrons
The portion of the renal tubule through which filtrate initially flows is known as the:
proximal tubule
Which portion of the renal tubule has a brush border created by the presence of many microvilli?
proximal tubule
Erythropoietin is produced by the kidneys to:
regulate red blood cell production by the bone marrow
The process of filtration occurs at the:
renal corpuscle
What are the two main subdivisions of the nephron?
renal corpuscle and renal tubule
In which kidney region are the renal pyramids located?
renal medulla
Urine drains from a major calyx into __________.
renal pelvis
What are the three main regions of the kidney?
renal pelvis, renal medulla, renal cortex
Which vessel is present in the arterial pathway but missing from the venous pathway?
segmental
Which of the following is NOT part of the urinary system?
spleen
Urine is transported from kidney to the urinary bladder by the:
ureter
