Lymph System Flashcards
What do lymph vessels do?
transport fluid back into blood
Characteristics of Lymph vessels
- one-way straw-like vessels that take lymph fluid back to the heart
- weave. b/w tissues and capillaries and absorb leaked fluid ( lymph )
- extremely permeable and are low-pressure vessels
Tissue type of lymph vessels
simple squamous epithelial cells
Why are lymph nodes permeable?
so proteins, cell debris, bacteria, and viruses can enter
Can lymph capillaries get inflamed easily ( T/F )
True
How is Lymph returned back to the Nervous System
the Right lymphatic duct/thoracic duct.
What duct drain lymph from the
right arm + right side of the head + Thorax
right lymphatic duct
What duct drain lymph from the rest of the body?
thoracic duct
do both the r lymphatic duct and thoracic duct drain into the subclavian veins (t/f)
True
Which duct drains into the Right subclavian vein
R. Lymphatic vein
Which duct drains into the Left subclavian vein
Thoratic Duct
what does the lymphatic vessles rely on for transport
Skeletal pumps
How do lymph nodes protect the body
- removing foreign materials form lymph
- houses lymphocytes that work with immune sysyem
What do the macrophages in LN’s do
engulf and destroy bacteria + viruses + other pathogens in lymph
What do the Lymphocytes in LN’s do
respond to foreign substances in lymphatic fluids prior to returning to blood.
Lymph node characteriscts
- kidney shaped
- less than 1 inch long
- buried in CT
Where are LN found?
along Vessels
Where are concentrated parts of LN
