Term
|
Definition
comprised of joined together lymphatic capllaries
resemble small veins
allow fluid to travel through out the body to the lymph nodes |
|
|
Term
|
Definition
have large amounts of lymphocytes and macrophages to fight invading organisms
less than 2.5cm and bean-shaped
capsule of fibrous connective tissue encloses each node and divides it into compartments called nodules
spaces in the them are called lymph sinus
nodules are the structural unit of the lymph node
can be superficial or deep |

Term
| FUNCTIONS OF THE LYMPH NODE |
|
Definition
filter potentially harmful particles from the lymph
immune surveillance sends macrophages and lymphocytes to make sure that the body is being protected |
|
|
Term
| LYMPHATIC TRUNKS AND DUCTS |
|
Definition
after leaving the lymph nodes, vessels become large tubes called trunks
enter into one of two ducts, thoracic or lymphatic.
Thoracic is longer and larger, gets lymph from the lower and left side of the body. Empties into left subclavian.
Lymphatic recieves lymph from the right side and empties into the right subclavian. |
