Lymphatic System Flashcards
What is the lymphatic system made up of?
Lymph fluid
Lymph vessels
Lymph nodes
Lymph organs and glands
What is the function of the lymphatic system? what does it prevent?
Maintains fluid levels in our body tissues by removing all fluids that leak out of our blood vessels. Prevents tissues from swelling.
Where does the excess fluid from the body’s tissues go?
Drains into small lymph vessels
What do cells use tissue (Interstitial) fluid for?
Cell metabolism
How does the lymphatic system involve the GI tract ?
the breakdown products of fat and fat-soluble materials are absorbed into the lymphatic vessels of the villi in the small intestine
What are lymphatic vessels?
A network of tubes that connect to groups of the lymph nodes throughout the body.
Vessels and capillaries.
Fluid travels through the lymph vessels and drains into the bloodstream (Subclavian vein)

Lymph is the fluid that flows through the lymphatic system, a system composed of lymph vessels and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to be recirculated.
Function of lymph nodes?
Where lymph is cleaned by reticular and lymphatic tissue.
Organic matter is destroyed.
What lymphocytes mature in lymph nodes?
T and B. Antibodies enter lymph and blood draining the node.
What are tonsils?
They are collections of lymphoid tissue.
Where is the pharyngeal tonsil?
A single tonsil at the back of the nasal cavity
