Lymphatic Capillaries | Random | Lymphatic Vessels | Lymphatic Trunks | Lymphatic Ducts |
---|---|---|---|---|
Lymphatic capillaries to vessels, to trunks, then to the ducts.
The order in which lymph travels
|
10% of fluid that exits capillaries isn't absorbed by capillaries; it is termed lymph fluid once absorbed by lymphatic vessels.
When does interstitial fluid become lymph fluid?
|
They both have 3 tunics & valves
Why do lymphatic vessels resemble small veins?
|
Jugular trunks
Drain lymph from the head & neck
|
Thoracic duct
The largest lymphatic vessel
|
Lacteal
A type of capillary that transports dietary lipids, lipid soluble vitamins, & interstitial fluid
|
Venous circulation
Where does the lymphatic vessels return this excess fluid before blood returns to the heart?
|
Pooling in the vessel & help prevent lymph backflow.
Valves prevent lymph from
|
Subclavian trunk
Drains lymph from upper limbs, breasts, & superficial thoracic wall.
|
Cisterna chyli
Receives chyle from the small intestine
|
Cell margin pushes back to the adjacent endothelial cell & now fluid is trapped in the lymphatic capillary. Fluid cannot be released back into the interstitial space.
What occurs when pressure increases in a lymphatic capillary
|
body tissues would swell (edema). It would also accumulate outside the circulatory system causing blood volume to drop.
What would happens if the excess isn't absorbed?
|
Lymph nodes
Some lymphatic vessels connect directly to
|
Bronchomediastinal trunks
Drains lymph from deep thoracic structures
|
Right lymphatic duct
Returns lymph into the junction of the right subclavian vein & the right internal jugular vein
|
A lymphatic capillary is larger, lacks a basement membrane, & has overlapping endothelial cells.
What is the difference between a blood capillary and a lymphatic capillary?
|
Lipids; chyle
The lymph from the GI tract has a milky color b/c of? What is it called?
|
Afferent lymphatic vessels
______ transport lymph to a lymph node where it is filtered for foreign or pathogenic antigens.
|
A single intestinal trunk
Drains lymph from most abdominal structures
|
Cisterna chyli
Left & right intestinal trunks drain into the
|
Lymph
combo of interstitial fluid, solutes, & sometimes foreign materials that enter the lymphatic vessels
|
Lymphatic vessels
Lymphatic capillaries merge to form
|
efferent lymphatic vessels
Once filtered, lymph exits lymph nodes via ______
|
Lumbar trunks
Drains lymph from the lower limbs, abdominopelvic wall, & pelvic organs.
|
From most regions of the left side of body, the junction of the left subclavian vein & left internal jugular vein
The thoracic duct receives lymph from & drains lymph to?
|
