Edema Flashcards
(46 cards)
causes protein wasting including albumin
Kidney disease
hi hydrostatic pressure causes
more fluid pushes out
The two Filarial worms are: BW
1 Brugia malayi
2 Wuchereria bancrofti
Since fluid continuously flows from arterial to venous side
= there are still pressures present (HPC, OPC, HPE, OPE) in venous side BUT only the HPE changed (35 mmHg -> 17 mmHg)
Why did HPE went down?
HPE has low water & hi solute concentration
= creates greater osmotic pressure in venous side
Formula for Net Filtration Pressure:
NFPA = Pressure OUT - Pressure IN
When sphincters closed blood flows through
metarteriole through fare channel & bypasses true capillaries
Where is albumin synthesized?
Liver
Filarial worms in lymphatic vessel causes (1) (2) (3)
(1) cause blockage
(2) making lv highly permeable
(3) fluid can backflow to ee
You pushed out 20 ml of fluid into arterial site when fluid goes back to venous end you will received less, 17 ml. Where did the 3 ml go? It will be taken by lymphatic system, why?
1 it provides proper blood volume
2 it cleanses the blood & returns it back to circulation via thoracic duct -> subclavian vein -> heart w proper heart vol
3 therefor, whatever antigen present it will be clean
WHAT CAUSES EDEMA OUTSIDE INFLAMMATION?
HLiCK:
Hypertension
Liver disease
consider pressure
Kidney disease
If fluid direction is outwards = _____; If fluid direction in inward = _____
(1) positive
(2) negative
regulates the movement of blood to the capillaries (meta arteriole -> true capillaries)
Sphincter
hi number of systolic or diastolic pressure
Hypertension
The system responsible for the ff:
If an antigen or foreign body enters the body, it sequesters fluid & circulates it as lymph
all of these lymph nodes are collected & end up in the thoracic duct it empties in the subclavian vein
lymphatic system
if parasites enters a person that resides in the lymphatic vessels provides antigen
LYMPHATIC SYSTEM
severe enlargement of the limbs, breasts, scrotum
Elephantiasis
cause lower solute concentration -> lowering osmotic pressure results in:
low albumin production
- lowers osmotic pressure
= no pressure to pull back fluid to circulation - cause summation / accumulation of fluid of out ee
= swelling & edema
the ff is due to
low albumin
Pressure in the capillaries, pulls fluid from extra environment going in the true capillaries
choose:
(1) Hydrostatic pressure
of the Capillary
(2) OPC: Osmotic pressure of the Capillary
(3) Systolic Pressure
Osmotic pressure
of the Capillary
Blood is composed of formed elements (1), (2), (3)
LET:
Leukocytes (wbc)
Erythrocytes (rbc) &
Thrombocytes (platelets)
Fluid component of blood that goes out to extracellular environment
Plasma
essential for creating osmotic pressure in venous side of capillary (allowing the pulling of fluid out from the external environment to venous end of the capillary)
function maintain proper blood vol thru sequestering fluid from ee down to the capillary bed in venous side so the proper vol of blood will be re circulated throughout the body
Albumin
Hemo: _____; Dynamic: ______
(1) blood; (2) movement of fluid within the vessels
In plasma ____ % water; ____% protein
(1) 95%
(2) 5%
