What are the organs of the lymphatic system
Lymph nodes Spleen Thymus Peyers Patches Appendix Tonsils
What is lymph
Fluid in vessels
What is a lymph nodes
cleanses lymph
What does lymphatic vessels do
Return interstitial fluid and leaked plasma proteins back to blood
What kind of system is the lymphatic vessels
One way system
What is the primary lymphoid organs
Red bone Marrow
Thymus
What is the secondary lymphoid organs
Spleen
Thymus
Tonsils
Lymph nodes
What is the lymphoid tissue in the digestive system
Mucosa-associated lymphoid tissue
What is the lymphoid tissue in the throat
Tonsils
What is the other name of the Left lymphatic duct
Thoracic duct
Where does the lymph system start
Lymphatic Capillaries
The lymphoid organs and tissues are what
the structural basis of the immune system
What are the functions of the lymphoid system
Drain excess interstitial fluid and plasma proteins from the tissues and bring it back to the heart via blood stream
Transport dietary lipids and vitamins from the GI tract to the blood
Facilitate immune response
What are the lymphatic capillaries that absorb fat from the small intestines
lacteals
What do lacteals contain
chyle
How does the fluid flow in the lymphatic system
Lymphatic Capillaries
Collecting lymphatic vessels
Lymphatic Trunks
Lymphatic Ducts
Where are the lymphatic capillaries found
Found everywhere besides in bone, Cartilage, and cornea
Structurally, how do lymphatic capillaries bring fluid in but not out
Endothelial cells over lap creating flaplike minivalve
Collagen fliaments anchors endothelial cells to surrounding structures, preventing collapse of lymphatic capillaries
How do lymphatic capillaries bring fluid in but not out
When fluid pressure in the interstitial space is greater vs lymphatic capillaries then minivalve flaps open bringing fluid inside.
Where does the Right side of the head, arm, and chest empty into
Right Lymphatic duct
Where does the left side of the the head, arm, chest and Lower Extremities empty into
Thoracic duct/ Left lymphatic duct
How does the the fluid in the lymphatic system move through the vessels
Milking action via the muscles
Where does the lymphatic trunk drain into
The L/R subclavian veins
What is the importance of the primary lymphatic organs
provide an environment for stem cells to divide and mature into B and T lymphocytes
