Three. two for ureters and one for urethra.

Question 12

Folds in mucosa are called:

Answer 12

rugae

Question 13

Answer 13

prevent backward flow of urine into the ureter.

Question 14

How many sphincters are there and where are there?

Answer 14

Two sphincters and they are where the urethra exits the bladder.

Question 15

Internal Schphinter is composed of:

Answer 15

smooth muscle and is involuntarily controlled.

Question 16

External Sphincter is composed of:

Answer 16

skeletal muscle and can be voluntarily controlled.

Question 17

When urinary bladder fills with urine, what is activated and what do they do?

Answer 17

stretch receptors and they send sensory nerve signals to spinal cord.

Question 18

Nerve impulses cause the urninary bladder to:

Answer 18

contract and causes the sphincters to relax.

Question 19

Urethra tends from:

Answer 19

the urinary bladder to an external opening.

Question 20

Question 21

Answer 21

Kidney structure:

Answer 22

Renal Cortex: outer layer
Renal medulla- inner layer and consists of tissue masses called renal pyramids.
Renal pelvis- central space that is continuous with the ureter.

Question 23

Kidneys are composed of which type of cell and what do they do:

Answer 23

nephrons. they filter the blood and produce urine.

Question 24

Several neurons empty urine into:

Answer 24

one collecting duct. these collecting ducts empty into renal pelvis.

Question 25

Blood supply of nephron passageway:

Answer 25

renal artery to afferent arteriole to blood to glomerulus to glomerular capsule. Then the efferent arteriole to peritubular capillary network.

Question 26

Efferent arteriole carries blood in which direction?

Answer 26

away from glomerulus.

Question 27

Blood pressure is highest in glomerulus because:

Answer 27

the efferent arteriole is narrower than the afferent arteriole.
