, lymph flow Lymphatic Capillaries --> Lymphatic Vessels --> Lymphatic Trunks --> Lymphatic
Ducts --> Subclavian Veins (blood stream)
Aid of lymph flow muscle pump, respiratory pump, contractions of vessel smooth muscle, valves
chyle white or pale yellow substance in lymph that contains fatty substances
absorbed by the lacteals
What causes interstitial fluid to move into a lymph Increased interstitial volume opens the lymph mini-valves, fluid enters the
vessel? lymph vessel becoming lymph, as a result there is a decrease in interstitial fluid
volume so mini-valves close.
plasma Fluid portion of blood
lymph fluid fluid that circulates through the body in lymph vessels and eventually enters
the bloodstream
interstitial fluid fluid found between the cells of the body that provides much of the liquid
environment of the body cells; composed of blood plasma without plasma
proteins
TERM DEFINITION LOCATION
right lymphatic duct drains lymph from right upper arm and right side of head and thorax
into right subclavian vein
TERM DEFINITION LOCATION
thoracic duct arises as cisterna chyli; drains lymph from rest of body. Empties lymph
into venous circulation at subclavian vein on left side of body.
Mechanism of Lymph transport 1. contraction of skeletal muscles
2. pressure changes in the thorax during inspiration
3. presence of valves in lymph vessels
4. pulsations of arteries
5. smooth muscle contractions of lymph vessels
