Lymphatic system consists of three parts.
1) A network of three parts
2) Lymph 3) Lymph nodes |
Similar to blood capillaries, except
Very permeable Endothelial cells overlap to form one-way minivalves.
Absent from bones, teeth bone marrow and the CNS
|
Drains the right upper arm and the right side of the head and thorax.
Right Lymphatic duct
|
Two main types of Lymphocytes
T Cells And B Cells
|
Two main types of Lymphatic tissue.
Diffuse Lymphatic tissue and Lymphatic follicles
|
Functions of the Lymphatic system.
Returns interstitial fluid and leaked plasma proteins back to the blood.
|
Specialized lymph capillaries present in intestinal mucosa.
Lacteals
|
arises from the cisterna chyli and drains the rest of the body.
Thoracic duct
|
What protects against antigens
Macrophages
|
Diffuse lymphatic tissue
comprises scattered reticular tissue.
|
Together with lymphoid organs and tissues, provide the structural basis of the ______ _______.
immune system.
|
Similar to veins, except Have thinner walls, with more internal valves.
Lymphatic collecting vessels
|
Right Lymphatic and Thoracic duct
each empties lymph into venous circulation at the junction of the internal jugular and subclavian veins on its own side of the body
|
Dendritic cells
Cells that capture antigens and deliver them to lymph nodes.
|
Lymphatic follicles
Germinal center
|
One way system,lymph flows toward the heart.
Lymphatic vessels.
|
Lymphatic trunks
Formed by the union of the largest collection ducts.
|
What is lymph propelled by
Pulsations of nearby arteries and Contractions of smooth muscle in the walls of the lymphatics.
|
Reticular cells
produce stroma that supports other cells in lymphoid organs.
|
Lymph nodes
Principal lymphoid organs of the body
|
what are the types of lymphatic vessels.
Lymphatic capillaries
Lymphatic collecting vessels Lymphatic trunks and ducts. |
Lymph
is delivered into one of two large ducts
|
Lymphocytes
The main warriors of the immune system
|
Lymphoid tissue
Houses and provides a proliferation site for lymphocytes
|
Functions of lymph nodes
Filter lymph and Immune system
