Passive diffusion involves?
Ultrafiltration is bulk flow through a?
Ultrafiltration involves starling forces such as?
Colloid Osmotic Pressure
Hydrostatic pressure gradient favors?
Capillary hydrostatic pressure averages?
17 mm Hg
Interstital hydrostatic pressure averages?
-3 mm Hg
Colloid Osmotic Pressure favors?
Capillary COP averages?
28 mm Hg
Interstitial COP averages?
9 mm Hg
Colloid osmotic pressure is a function of the?
Plasma proteins include?
Calculated colloid effect is?
19 mm Hg
Actual colloid effect is?
28 mm Hg
What increases colloid osmotic effect?
Large plasma proteins carry negative charges which attract positive ions. This increases the osmotic effect by?
Capillary walls can range from
Tight junctions to discontinuous
Glomerular capillaries in kidney have?
Filtration Slits (Fenestrations)
Only the protein that cannot cross capillary wall can exert?
What expresses how readily protein can cross capillary wall?
Reflection coefficient ranges between?
0 to 1
If reflection coefficient is 0, all colloid proteins freely cross wall, none are reflected therefore?
No colloid effect
If reflection coefficient is 1, all colloid proteins are reflected, none cross capillary wall, therefore?
Full Colloid Effect
What drains excess fluid from interstitial spaces?
No true lymphatic vessels are found where?
Superficial portions of skin
Endomysium of muscle and bones
What drains the lower body and left side of head, left arm and part of chest as well as left leg?
What drains the right side of the head, neck, right arm and part of the chest?
Right Lymph Duct
There are not true lymphatic vessels in the?
What contains CSF and communicates with subarachnoid space?
Plasma filtrate and escaped substances in perivascular spaces are returned to vascular system in the CSF via?
