16
Q

Describe outer cortex

A

Continuous layer - renal columns

17
Q

Describe cortex and medulla

A

Multiple functional lobes (5-10 per kidney)

18
Q

What mostly makes up a medullary pyramid

A

Nephrons - tubes that filter blood and create urine

19
Q

Where do the papilla drain

A

Into calyx

20
Q

Where do the calyces join

A

Renal pelvis - narrows to ureter

21
Q

Where does filtration occur

A

Cortex of the kidney

22
Q

What artery supply’s blood to the kidneys

A

Renal artery - from abdominal aorta

23
Q

What happens after blood is filtered

A

Veins return filtered blood from cortex to renal vein to IVC

24
Q

What delivers blood to the glomerulus

A

Afferent arteriole from arteries

25
Q

What makes up the glomerulus

A

Glomerular capillaries - where filtration occurs

26
Q

Where does blood go after the glomerulus

A

To the Peritubular capillaries then to the veins

27
Q

What is the nervous system that supplies the kidneys

A

Renal plexus - network of autonomic nerves and ganglia

28
Q

How do sympathetic nerves affect kidneys

A

Adjust diameter of renal arterioles - regulate blood floe
