Why it matters
What is the main function of the lymphatic system
return fluids that have leaked from the vascular system back to the blood
How does the lymphatic system help maintain fluid balance in the body?
collecting excess lymph from tissues that leaks from blood capillaries and returns it back to the blood steam, through the subclavian veins.
function of Lymphatic nodes
cleanses lymph and activates the immune system
how does lymphatic system work with the cardiovascular system?
the lymphatic system maintain fluid balance by collecting excess interstitial fluid from tissues and returns it to the blood stream via the subclavian veins preventing tissue swelling
what are the names of the cells in the primary lymphoid organs
T cells, B cells
What are the main structures of this system?
lymphatic vessels, lymph, and lymph nodes
What else do the lymphatic vessels do
- return leaked proteins to the blood
- carry pathogens and cancer cells to lymph nodes
- carry absorbed fat from the intestines to the blood
what are dendritic cells
cells that bring antigens to lymph nodes
how does lymphatic system work with the immune system
the lymphatic system acts as defense network, the system transports lymph containing WBCs through lymph nodes, which filter out bacteria, viruses and toxins. The Spleen also filters blood to remove old RBCs
what are lymphocytes
WBC that are essential for the immune system. They destroy pathogens, fight bacteria and tumor cells.
What are the lymphatic vessels?
Lymphatic Vessels form a ____ system
oneway
what are macrophages?
they destroy pathogens and debris so they aren't delivered to the blood and then spread elsewhere (eaters)
how does the lymphatic system work with digestive system
the system absorb fats and fat soluble vitamins from digestive tract transporting fluid into blood stream
which bone marrow is in the thymus
red bone marrow
Purpose of the lymph
protein containing fluid that moves through lymphatic vessels
where do the lymphatic vessels unite?
lymphatic trunks
What does the Spleen do for this system?
cleanses blood and removes defective RBCs, debris and foreign substances in the red pulp tissue
how does lymphatic system work with CNS
lymphatic vessels connect the brain and spinal cord to the immune system managing the flow of cerebrospinal fluid
Function of the THYMUS
where t cells mature so they can defend against pathogens
Which are apart of the Lymphoid Organs?
spleen, thymus and tonsils
What is the correct way the lymph nodes to the heart
lymphatic capillaries --> collecting lymphatic vessels --> lymph nodes ---> lymphatic trunk ---> lymphatic duct ---> heart
how is lymphedema connected to lymphatic system
lymphedema is chronic swelling, usually in legs or arms causes by malfunction or damage to lymphatic system
how does lymphatic system work with musculoskeletal system
lymphatic vessels remove waste products from tissues, while muscle contraction and breathing help push lymph through vessels as the system lacks its own pump
What is MALT
mucosa associated lymphoid tissue
