Q

It is fine to work the lateral territory on the upper arm area that is swollen due to removal of axillary lymph nodes because the lymph collectors drain also into the supraclavicular lymph nodes.

Q

What are the four main components of the Lymphatic Load?

A

42
Q

What represents the beginning of the lymphatic system?

A

Lymph Capillaries

43
Q

What percentage of water is reabsorbed from the interstitial tissues back into the blood capillaries in a healthy body?

A

80-90%

44
Q

What percentage of water remains in the interstitial space and becomes Lymphatic Load of water?

A

10-20%

45
Q

How much lymph fluid is normally returned to the venous system in 24 hours?

A

2-4L

46
Q

What percentage of the total circulating blood proteins leave the capillaries and move into the interstitial space in 24 hours?

A

50%

47
Q

Where do the proteins end up after leaving the blood capillaries?

A

Interstitial space

48
Q

How do proteins get back into the blood?

A

Lymphatic system

49
Q

Which lymphatic structures filter lymph fluid?

A

Lymph nodes

50
Q

Where does the fat portion of the Lymphatic Load come from?

A

Chylous vessels of the small intestine

51
Q

Which structures comprise the superficial lymphatic system?

A

Initial lymph capillaries, precollectors, and lymph collectors

52
Q

Where is the deep lymphatic system located?

A

Beneath the fascia

53
Q

What is the purpose of the deep lymphatic system?

A

Drains the muscles and tendons
Drains the joints
Drains the inner organs

54
Q

Which structures first pick up the Lymphatic Load and thus begin the lymphatic system?

A

Initial lymph capillaries

55
Q

What is the purpose of the initial lymph capillary?

A

Lymph formation

56
Q

What is the purpose of pre-collectors?

A

Connect superficial capillaries to superficial collectors

57
Q

Where are the superficial collectors located?

A

In the superficial fatty tissue, above the fascia

58
Q

What is the purpose of the collectors?

A

Transport lymph to lymph nodes and lymphatic trunks

59
Q

What do perforating pre-collectors do?

A

Connect the superficial and deep lymphatic system
