Flashcards in Blood Vessels chp 26 and Lymph chp 27 Deck (13):
1

Blood vessels

carry blood from heart to organs and back
space w in BV = lumen

2

Artery

away from heart
walls - smooth muscle and elastic fibers - carries pulse and extension of vessels
branching lead to arterioles (same composition)

3

Capillaries

connections btw arterioles and venules
exchange of nutrients and waste from blood and tissue

4

Vein

from venules, by tributaries, carry blood back to heart
thinner wall than artery
most have valves (one way flow to heart)
blood moves past valves via contraction of surrounding muscles

5

Lymphatic system

takes care of excess fluid filtered out of capillaries which exceeds reabsorbed amt

6

Lymphatic capillaries

pick up excess fluid moving it towards veins, endothelial tubes, begin blindly (not open at both ends)
excess fluid = lymph

7

Afferent lymphatic vessel

several lymphatic capillaries joining together
have folds that form valves
convey lymph to lymph nodes

8

Lymph nodes

filter lymph
have cortex and medulla

9

Efferent lymphatic vessels

leaving lymph nodes
pass lymph to venous system

10

Right lymphatic duct

drains right half of head, neck, chest and right upper limb
end in brachiocephalic or tributaries

11

Thoracic duct

drains rest of body
end in brachiocephalic or tributaries

12

Cisterna Chyli

collects lymph inferior to diaphragm
flows superiorly forming thoracic duct

13

Lymph nodes are prevalent where...

Inguinal, axilla, neck
