Question 9

Interstitium

Answer 9

Space between tissue compartments

Question 10

Where does tissue edema accumulate

Answer 10

Interstitium

Question 11

Starling equilibrium

Answer 11

Equation to show fluid movement due to filtration across the capillary walls, balance between filtration and absorption pressure

Question 12

Colloidal-osmostic pressure

Answer 12

Oncotic

Question 13

Filtration pressure

Answer 13

Difference between hydrostatic and colloidal osmotic pressure in arterial end of capillaries

Question 14

Absorption pressure

Answer 14

Difference between hydrostatic and colloidal osmotic pressure in venous end of capillaries

Question 15

What compensates for the difference between the filtration and absorption pressures

Answer 15

Lymphatics

Question 16

What systems work together to maintain fluid balance

Answer 16

Circulatory and lymphatic

Question 17

What happens when water and electrolytes escape the circulatory system faster than they can return

Answer 17

Edema

Question 18

In edema, there is a decrease in ____ and and increase in ____

Answer 18

Plasma colloidal-osmotic pressure; hydrostatic

Question 19

Colloidal-osmotic pressure

Answer 19

Effect of large molecules in solution on the chemical potential of water

Question 20

What exert the main osmotic pressure to oppose the hydrostatic pressure in capillary beds

Answer 20

Proteins, specifically albumin

Question 21

Hypoalbuminemia

Answer 21

Low albumin, leads to low colloidal-osmotic pressure and edema

Question 22

If the hydrostatic pressure increases in the venous end of the capillary…

Answer 22

Fluid filtered at the arterial end fails to return to circulation, results in edema

Question 23

Ascites

Answer 23

Swelling of the abdomen

Question 24

Pathophysiology of edema

Answer 24

Decreased PCO pressure, increase blood hydrostatic pressure, lymphatic obstruction, vascular permeability

Question 25

Lymphatic filariasis

Answer 25

Obstructive edema, blockage of lymph drainage

Question 26

Edema of inflammation causes what?

Answer 26

Increased vascular permeability

Question 27

Edema in pigs

Answer 27

Proliferation of E. coli in intestines, STEC, Stx2e toxins, edema in submucosa of stomach, causes damage to CNS

Question 28

Hydrallantois

Answer 28

Edema in allantois, caused by placental/uterine dysfunctions

Question 29

Hydramnios

Answer 29

Edema in amniotic space

Question 30

Udder edema

Answer 30

More common in heifers, in the winter, high K and Na, low Mg intake during dry period
