Lymphatic System Part 5

Question 1

How does Fluid get from the Blood to the Lymphatic system?

Answer 1

Hydrostatic Pressure
Osmotic pressure
Filteration
Reabsorbtion

Question 2

how many Litres per day does the Lymph system turnover

Answer 2

8 Litres

Question 3

What is the main process of fluid exchange and what is it affected by?

Answer 3

Filtration is the main process of fluid exchange. It is affected by Hydrostatic pressure and osmotic absortion

Question 4

Filtration is a type of?

Answer 4

Hydrostatic pressure that forces fluid out of the capillaries

Question 5

What is Filteration (blood capillary pressure) influenced by and where is the pressure greatest?

Answer 5

It is influenced by interstitial pressure and is greatest on the arterial side and less on the venous side.

Question 6

What is Osmosis?

Answer 6

Water movement due to proteins

Question 7

What is active Hyperemia?

Answer 7

Increased capillary permability eg heat, exercise and inflammation

Question 8

What is passiveHyperaemia?

Answer 8

Increased capillary Hydrostatic pressure eg DVT, congestion heart failure, CVI

Question 9

What does Lymphatic Load refer to?

Answer 9

To the amount of substances and fluid that have to be removed from the instertium by the system

Question 10

What is Transport capacity of the Lymphatic system equal to?

Answer 10

The max lymph time volume. Our Lymph system usually works at 10% of it capacity

Question 11

Lymphatic Drainage is determined by?

Answer 11

The Lymphatic circulation and the extrisic muscle pump during exercise.

Question 12

Describe the Process of Lymphoedema

Answer 12

1. Lymphoedema is caused by an accumulation of protein rich fluid in the intersititum.
2. The interstitial fluid stagnates with the accumulation of protein, macromolcules, hyauronic acid, fat, water and cell debris.
3. Hypertension develops causing further damage.
