  1. Filters blood
  2. Eliminates nitrogenous wast
  3. Maintains fluid balance
  4. Contols levels of iorn
  5. Regulates blood pH

2

Renin

3

What hormone plays a role in RBC production (erythropoiesis)

Erythropoietin

4

Name 3 processes influanced by the Urinary System:

  1. Urine Formation
  2. Regulation of blood pressure
  3. Regulation of RBC production

5

Name the 4 organs of the Urinary System:

  1. Kidneys
  2. Ureters
  3. Bladder
  4. Urethra

6

The bladder consists of ________ epithelium?

transitional epithelium

7

Name the 5 parts major parts of the Kidneys:

  1. Cortex
  2. Medullla
  3. Calyses
  4. Pelvis
  5. A series of arteries and veins

8

Name the outermost region of the kidney.

Cortex

9

Name the striped, middle pyramid region of the kidneys

Medulla

10

Name the finger-like trough found in the Kidneys.

Calyses

11

Name the basin area, continuous with the ureters found in the Kidneys.

Pelvis

12

What is the smallest functional unit of the Kidney?

The Nephron

13

Name the 2 parts of the Renal Corpuscle:

  1. Glomerulus
  2. Bowman's Capsule

14

The __________ part of the Renal Corpuscle is refered to as a "high pressure capillary bed."

Glomerulus

15

The Glomerulus is fed by ________ arterioles, and drained by ________ arterioles.

fed by afferent,

drained by efferent

16

The diameter of:

- Afferent

or

- Efferent 

areteriols are bigger?

afferent

17

Name the 4 Renal Tubules:

  1. Proximal Convoluted Tubule
  2. Loop of Henle
  3. Distal convoluted tubule
  4. Collecting tubules

18

What type of epithelium are found in the Proximal Convoluted Tubule.

What additional structure is found here?

Simple Cuboidal epithelium

and

Contains microvilli

19

What type of epithelium is found in the loop of Henle?

Simple Squamous epithelium

20

What type of epithiium is found in the Distal convoluted tubule?

 

Simple Cuboidal epithelium

21

What type of epithilium is found in the Collecting tubules?

Symple Cuboidal epithelium

22

What are Peritubular Capilary Beds?

"capillaries that surround tubules"

23

Name 3 carictoristics of the Peritubular Capillary Bed:

  1. They are low pressure and porous
  2. They arises from efferent arterioles
  3. They cling to the renal tubules

24

Name the 3 processes of Unine Formation:

  1. Filtration
  2. Reabsorption
  3. Secretion

25

Where does filtration occure?

By passage from the Glumerulus into the Bowmans capsule

26

Where does reabsorption occure?

Proximal convoluted tubules and loop --> peritubular capillaries

27

Where does Secretion occure?

Peritubular capillaries --> distal convoluted and collecting  tubules
