Q

What is the name of the cells that produce renin and that the macula densa communicates with?

A

Juxta-glomerular cells

14
Q

T/F the glomerulus is the capillaries only

A

True

16
Q

What is the name of the outer part of the kidney?

A

Cortex

17
Q

Describe the macula densa cells

A

Condensed and regularly alined

18
Q

What feature do the epithelials of the proximal tubule have?

A

Brush border with long microvilli

19
Q

What is the structure of podocytes?

A

They surround glomeruli capillaries and give up interdigitating fingers (pedicles) that assist in filtration

21
Q

What type of cell make up the wall of the thin loop of Henle?

A

Simple squamous cells

22
Q

What is the name of the cells the surround the capillary of the glomerulus and provide support and filtration?

A

Mesangial cells

Podocytes

23
Q

Which has more mitochondria, the proximal or distal tubule?

A

Distal

25
Q

What is the difference between interlobular vessels and interlobar vessels?

A

Interlobular are given off at right angles to the arcuate vessels while interlobar run in between medulla towards the cortex

26
Q

What is the name of the vessels that lie at hte boundary of the cortex and medulla?

A

Arcuate vessels

27
Q

T/F there is peristalsis in the ureter

A

True - regulated by autonomic nerves

28
Q

Describe the epithelials of the collecting duct

A
