Question 1

They are microscopic lymph vessels, which weave between the tissue cells and blood capillaries in loose connective tissue of the body.

Answer 1

LYMPH CAPILLARIES

Question 2

Lymph capillaries are found almost everywhere blood capillaries occur except in:

Answer 2

bone, teeth, bone marrow and CNS

Question 3

Two unique structural modifications that causes Lymphatic capillaries became very permeable:

Answer 3

Endothelial cells

Bundles of fine filaments

Question 4

___________ forming the walls of lymphatic capillaries are not tightly joined. Their edges are loosely overlapped forming mini-valves.

Answer 4

Endothelial cells

Question 5

_____________ anchor endothelial cells to surrounding structures so that any increase in _________________ separates the cell flaps exposing gaps in the wall therefore the lymph capillaries will not ________ .

Answer 5

Bundles of fine filaments
interstitial fluid volume
collapse

Question 6

These modification resemble one way swinging doors in the lymphatic capillary wall. When pressure is ____________ the ‘doors’ they ___________ and lymph moves into capillaries.

Answer 6

greater outside

swing open

Question 7

These modification resemble one way swinging doors in the lymphatic capillar y wall. When pressure is ___________ the
‘doors’ they _______ so lymph can not leak backwards.

Answer 7

greater inside

close

Question 8

When tissue becomes inflamed, lymphatic capillaries develop openings that permit larger particles into the lymphatics such as:

Answer 8

debris, pathogens and cancer cells

Question 9

They have the same tunics (layers) as veins but have thinner walls and more internal valves.

Answer 9

Lymphatic Collecting Vessels

Question 10

What vessels in skin travel along with superficial veins?

Answer 10

Collecting vessels

Question 11

What vessels of the trunk and digestive viscera travel with the deep arteries?

Answer 11

Deep lymphatic vessels

Question 12

___________ - vessels of the vasa vasorum become congested with blood due to lymphatic vessels becoming severely inflamed, and the pathway of the associated ___________ become visible through the skin as red lines that are tender to the touch.

Answer 12

Lymphagitis

superficial lymphatics

Question 13

These trunks are formed by a union of the largest collecting vessels and drain fairly large areas of the body.

Answer 13

Lymphatic Trunks

Question 14

The trunks are named for the region from which they collect lymph:

Answer 14

Paired lumbar 
Paired bronchomediastinal 
Paired subclavian 
Paired jugular  
Single intestinal trunk
