Lymphatic System Flashcards
There is high pressure in both the
- Heart
- Blood vessels
What is the function of the high pressure found in the heart and blood vessels?
It forces fluid out of the vessels
What is the function of lymphatic vessels?
It collects pushed out fluid and brings it back into circulation
Lymphatic vessels lack
A closed loop
Which cells line capillaries?
Endothelial cells
What pulls fluid back into the lymphatic vessels?
The higher osmotic pressure
What is lower in the latter part of the capillary?
Hydrostatic pressure
Lymphatic vessels pull in
- Fluid
- Proteins
How is the size of lymphatic vessels?
They start small and then get larger as they branch
Lymph is able to return to the high pressure system due to
- Location of reentry
- Valves
Lymph enters the circulatory system at the
End of venous circulation system
The pressure in veins is much lower compared to
Arteries + capillaries
Specifically, where does lymph reenter in the circulatory system?
Subclavian veins near the heart
T Cells + B Cells get swept in the lymphatic system and then are swept into
Nearest lymph nodes
What is the function of lymph nodes?
They filter fluid placed back into the bloodstream and prevent bacteria from going back into the bloodstream
