AP2 study set
How many segments does the male urethra have
3
Which type of nephrons are the majority?
Cortical
This structure is a capillary bed from which blood is filtered into the nephron
glomerulus
The juxtamedullary nephrons
have a nephron loop that penetrates deep into the renal medulla, and play an important role in concentrating urine
The renal artery enters the kidney at this indented area
hilum
Urine is formed by three processes. In which process do filtrate components that are useful to the body move form the nephron into the blood?
tubular reabsorption.
Which hormone stimulates production of concentrated urine?
ADH
This transports urine from the kidney to the urinary bladder
Ureter
Which is the correct order of filtrate flow
G. capsule, PCT, Nephron loop, DCT, collecting duct
This is the first step of urine formation
Glomerular Filtration
As urine is formed it flows through the collecting ducts to enter, in order, the following structures
Minor calyces, major calyces, renal pelvis, ureter.
This is the last step of urine formation:
Secretion
The vessel that supplies blood to the nephron is called the
afferent arteriole
During filtration in the nephron substances move
from the glomerulus into the nephron
This is the second step of urine formation:
reabsorption
The portion of the kidney that extends between the renal pyramids is called the
renal columns
The outermost portion of the kidney is called the
renal cortex
Calyces merge into the kidney's __________.
renal pelvis
The kidneys release
renin
The micturition reflex is triggered by which of the following?
sacral spinal cord
