Lymph moves out of the lymphatic trunks into one of the two ducts.
Lymphatic Ducts
What are the two Lymphatic ducts?
Right lymphatic duct
Thoracic duct
The duct that drains lymph from upper right arm and right side of head.
Right lymphatic duct
___________ - drains lymph from rest of body.
Thoracic duct
Two junction that each terminal duct empties the lymph into the venous circulation:
internal jugular vein
subclavian vein
Thoracic duct has enlarged pouch-like structure called: ________ which is a storage area for lymph.
cisterna chyli
The cisterna chyli collects lymph from the two large__________ that drain the lower limbs and from the ____________ that drains the digestive organs.
lumbar trunks
intestinal trunks
Complete the Lymph Transport
_________ is pumpless. It relies on movement of skeletal muscle, pressure changes within.
the ________ during breathing and valves to move lymph and prevent back flow.
Smooth muscle in the walls of the___________and___________contracts rhythmically, which helps to move lymph along.
When physical activity or passive movement _________, lymph flows much more rapidly
Anything that prevents the normal return of lymph to the blood such as a blockage of lymphatics by tumors results in ________________ .
If ___________ are removed surgically, lymph drainage will eventually re-establish itself by re-growth from the vessels still remaining in the area.
Lymph system thorax lymphatic trunks thoracic duct increases severe localized edema lymphatics
What consists the Lymph Cells?
Lymphocytes
Lymphoid Macrophages
Dendritic Cells
Reticular Cells
Lymph cells that arise from red bone marrow is called:
Lymphocytes
Two varieties of immunocompetent cells.
T-cells
B-cells
What is the main function of T-cells and B-cells?
They act to protect the body against antigens
_____________ manage the immune response and some of them directly attack and destroy foreign cells.
Activated T-cells
How does B - cells protect the body?
B - cells protects the body by producing plasma cells, which secrete antibodies into the blood.
Lymphoid Macrophages protects the body by phagocytizing foreign substances and by ____________________.
helping to activate T-cells.
