What is the use of the lymphatic system?
Draining of excess interstitial fluid
Draining of RBC trapped in the tissues
Immunological response
Fat transport
Amino acid transport
Put the method of lymphatic travel in order A- Lymphatic Trunks B- Lymph Ducts C- Lymph Nodes D-Lymphatic Vessels E- Lymphatic capillaries
E-D-C-A-B
E-C-D-A-B
E-D-C-B-A
What is the name of lymphatic capillaries in the G.I tract?
Lactoles
Vesicles
Vectoles
What makes up the anchoring filaments of the lymphatic capillaries?
Elastic fibres
Actin
Myosin
What is different about the endothelial cells of the lymphatic system?
They overlap
They compete with each other for space
They have holes for R.B.C's
Can epithelial cells lining the lymphatic capillaries move?
Yes
No
Name the deep lymph nodes
Thoracic
Abdomial
Pelvic
Ingurial
Auxillary
Cervical
Name the Superficial Nodes?
Inguinal
Supatochlear
Abodominal
Where are the folicles found in the lymph nodes?
Medulla
Capsule
Subcapsular sinus
Cortex
What is the role of reticular fibres in the lymph nodes?
To trap & filter blood pathogens
To stabilise the B lyphocytes
To hold the nodular capsule together
What is the role of afferent lymphatic vessels?
Bringing lymph to the node
Removing lymph from the node
Binding the node to the surrounding tissue
Why do folicles stain less in the middle?
They are germinal centres, that stain less
They are T lymph aggregates, that stain less
They are aggregated pathogens, that stain less
What are germinal centers?
Where B cells have aggregated in response to pathogens
Where reticular fibres have aggregated
Where the subcapsular sinus has poked through
What are found in germinal centres, other than lymphocytes?
Dendritic cells
Pathogens
Collagen
Epithelial cells
What is the role of the germinal centres?
To bring pathogens into contact with lymphocytes?
To bring pathogens into contact with macrophages
To bring pathogens into contact with reticular fibres
Right Subclavan Trunk, Right Jugular Trunk & Bronchiomediastrin Trunk drain into what duct?
Right Lymphatic Duct
Right Thoracic Duct
Right Abdominal Duct
Which ducts are found on both the left and right sides?
Subclavan
Jugular
Bronchmediastinal
Lumbar
Intestinal
What is the name of the ducts that trunks empty into?
Left/Right Lymphatic
Left/Right Subclavan
Left/Right Lumbar
Name the Primary Lymphatic Organs
Red bone marrow
Yellow bone marrow
Spleen
Thymus
What is the role of primary lymphatic organs?
Where immune cells divide and become immunocompetent
Where immune cells divide and bring pathogens to be destroyed
Where immune cells are destroyed
What is the role of secondary lymph organs?
Where immune response occurs
Where immune response is controlled
Where immune response ends
Name the secondary lymph organs
Lymph nodes
Bone marrow
