heart/lungs/abdominal cavitites
2 serous membranes
Parietal = wall
visceral = lines organs
ultrainfiltrate

20

pericardia
and peritoneal is

A

pleural - lungs
pericard - heart
periton - abdominal

21

continuous hydrostatic pressure/oncotic pressure

22
Q

Describe Effusion

A

accum of serious fluids (too much)

23
Q

Describe transudate

A

systemic disorder distrupts fluid filtration

24
Q

Describe exudates

A

occurs with inflamation and damage to walls

25

locations (paretal/viseral)
how much fluid

transudates
exudates

A

systemic (paretal)
bronchial (viseral)
3-20ml of fluid

Transudates: secondary to remote

Describe pericardial fluid

A

similar to lungs
effusions around the heart and almost always EXUDATES
<50ml of fluid

29

Describe Peritoneal fluid
how much is disease
excess is called
what is the primary

A

> 50ml disease
excess fluid = ascities
primary is exudates
untrasounds
