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
