Flashcards in Final Exam Deck (13):
1

Capillary Bed

extensive branching networks formed by the capillaries

2

Capillary filtration (bulk flow0

Mass movement of fluids and solutes between the blood and if as a result of the hydrostatic and asmotic pressure gradients that exist across the walls of the capillaries

3

Starling forces

Bulk flow or filtration across the capillary walls is driven by 4 forces collectively

4

Capillary hydrostatic pressure

the blood pressure in the capillary bed that varies depending on arterial pressure. Exerted on vessel walls by fluids

5

Interstitial fluid hydrostatic pressure

extremely low throughout the capillary bed under normal conditions. Exerted on the vessel walls by fluids

6

Plasma colloid osmotic pressure

created by the pressure of non-filterable proteins in the plasma. 25mmHg

7

Interstitial fluid colloid osmotic pressure

created by the non-filterable proteins in the plasma. 0 mmHg

8

Ultrafilteration

a positive net exchange pressure on the arteriolar end of the capillary bed

9

Reabsorption

a negative net exchange pressure on the venular end of the capillary bed

10

Net Exchange Pressure

(Pc + pieIF) - (PIF + pieP)
Capillary Hydrostatic pressure + Interstitial fluid colloid osmotic pressure - interstitial fluid pressure + plasma colloid osmotic pressure)

11

Edema

Excessive accumulation of interstitial fluid in a tissue

12

Lymphatic capillaries

smallest vessels of the lymphatic system. Closed-ended vessels found widely dispersed in the capillary beds of most tissues

13

Lymph

When interstitial fluid containing its solutes, cells and particulates enters the lymphatic capillaries
