Anatomy of the Lymph Vessel System

Question 1

What is the most important task of the lymph vessels?

Answer 1

The drainage and transport of interstitial fluid, along with various substances contained in it, into the venous blood circulation.

Question 2

True or False: The goal of manual lymph drainage and complete decongestive therapy is to improve or restore lymph drainage that has become imparied?

Answer 2

True

Question 3

Name three differences from blood vessels in regards to lymph vessels.

Answer 3

They are not a component of a closed circuit, do not have a central pump comparable to the heart, and have interposed lymph nodes.

Question 4

Name the four sub division sections

Answer 4

lymph capillaries, collectors, trunks, precollectors.

Question 5

T or F. Collectors and trunks serve to train the interstitial fluid?

Answer 5

False

Question 6

Name 4 characteristics of lymph capillaries

Answer 6

Cover the body like a net of valveless vessels. They are larger in diameter than blood capilaries. Have flap valves that enable the inflow of interstitial fluid. Begin with finger-like protrusions in the tissue. Consist of endothelial cells, a basal membrane, and so -called anchor filaments. Have no valves insdie the vessels.

Question 7

Where are the prelymphatic channels located?

Answer 7

Between the blood capillaries and the lymph capillaries.

Question 8

T or F: In the framework of a therapeutic session, lymph flows from lymph capillaries can be shifted in a desired direction.

Answer 8

True

Question 9

Describe precollectors

Answer 9

They are connected to the lymph capillaries and function somewhat like capillaires and somewhat like collectors. Like capillaries, they precolectors have sections in which interstitial fluid is reabsorbed. They also transport lymph to the collectors.

Question 10

What is the main function of collectors?

Answer 10

They are the actual lymph transport vessels.

Question 11

T or F. The valves of the collectors are active and not passive.

Answer 11

False.

Question 12

T or F. When a collector is blocked, the lymph can easily be detoured to aother lymph vessels.

Answer 12

True

Question 13

Name two of the three types of of tissues that deep (intrafascial) collectors of the extremeties and trunk drain?

Answer 13

They drain the relevant muscles, joints and ligaments.

Question 14

Describe fluid flow and compare it to vein flow

Answer 14

Unlike the veints, the direction of the fluid flow is pirmarily from below the the surface. Treatment of the surface vesels automatically improves the emptying of the deep vessels. This is a suction or water-pump effect.

Question 15

What are the largest lymph vessels called?

Answer 15

Lymph trunks.

Question 16

Where do lymph trunks take the flow of lymph?

Answer 16

They tank lymph from the inner organs to the extremities and to the sections of the trunk pertaining to them (trunk quadrants).

Question 17

Where is lymph from the lower extremities taken?

Answer 17

As well as the pelvic region. These are taken from the truncus lumbalis dexter and from the truncus lumbalis sinister. These two lumbar lymph trunks join with the truncus gasrointestinalis and then run to the ductus thoracious.

Question 18

What is the largest lymph trunk in the body?

Answer 18

Ductus thoracicus

Question 19

Where is the cisterna chyli located?

Answer 19

It is 3-8 cm long and lies below diaphram at the level of the first lumbar vertebra.

Question 20

What transports intestinal lymph?

Answer 20

Truncus gastrointestinalis

Question 21

What are the three central lymph trunks?

Answer 21

Truncus jugularis, Truncus subclavius, truncus bronchomediastinalis.

Question 22

What region drains from the axillary nodes, receives lymph from the upper trunk quadrants, the thoraci gland, and the arm?

Answer 22

Truncus subclavius

Question 23

What transports lymph from the bronchials, the lungs and the mediastinum?

Answer 23

Truncus bronchomediastinalis

Question 24

The three main lymph trunks come together on the right side to form a thick common trunk called?

Answer 24

Ductus lymphaticus dexter.

Question 25

The three main lymph trunks come together on the left side to form a thick common trunk called?

Answer 25

Ductus thoracicus

Question 26

The vena jugularis interna and the vena subclavia are joined behind the collarbone to the large what?

Answer 26

vena brachiocephalica

Question 27

What is the cutoff point for the lymph of the lower half of the body?

Answer 27

Anything below the diaphram

Question 28

the lymph of the lower half of the body as well as the left upper body quadrant flows through the ductus thoracicus to the left venous angle. T or F

Answer 28

True

Question 29

The right upper quadrant of the body is drained by what into what?

Answer 29

Drained by the ductus lymphaticus dexter into the right venous angle

Question 30

What is the venous angle?

Answer 30

The place where the two veins, vena jugularis interna and vena subclavia are joined.

Question 31

Name 3 characteristics of a lymph nodes structure

Answer 31

Bean shaped, 2 to 3 cm long, internal cell network siilar to a filter, a real organ with its own blood vessel and supply of nerves.

Question 32

True or False. Normally lymph nodes are not palpable.

Answer 32

True

Question 33

Describe efferent vessels and afferent vessels

Answer 33

The lymph enters the node in the afferent lymphatic vessels, and leaves the node in the efferent lymphatic vessel.

Question 34

What is the entrance for the lymph nodes into the veins called

Answer 34

Hilus

Question 35

T or F. The overall diameter of the afferent lymph vessels is smaller than that of the efferent lymph vessels.

Answer 35

False.

Question 36

The legs, outer genitals, and lower trunk quadrant below to the the tributary region of what nodes

Answer 36

Inguinal.

Question 37

The tributary regions are seperated brom one another by what?

Answer 37

Lymphatic watersheds.

Question 38

How many quadrants are created with watershds?

Answer 38

Four. Two above the navel and two below the navel.

Question 39

What does tributary region mean?

Answer 39

Also known as trunks which drain large regions.

Question 40

Describe prelymphatic channels

Answer 40

They bridge lymphatic watersheds whic hconnect blood capilaries to lymph capilaries and run along the connective tissue fibers,
