Primary Organs
This organ is where blood cells are produced, including lymphocytes
What is bone marrow
Thin-walled vessels that carry lymph from tissues toward the heart
What are lymphatic vessels?
Chemicals are sent out by injured cells, which result in inflammation
These microscopic vessels collect interstitial fluid from tissues
What are capillaries?
Site of antigen presentation and lymphocyte activation
What are lymph nodes?
Where T-cells migrate after development in the bone marrow
What is the thymus
Main function of the lymphatic system is to return this to the circulatory system
What is interstitial fluid?
Any of the white blood cells that ingest a pathogen
what are phagoctyes
returns lymph from the right side of the head and neck, the upper right quadrant of the body, and the right arm;
What is the right lymphatic duct?
Filters blood and responds to blood-borne antigens
What is the spleen?
What is the thymus?
This type of white blood cell is the most abundant in lymph and essential for immune defense
What are lymphocytes?
any part of a pathogen that generates the production of antibodies (often a protein produced by a bacteria or virus)
What is an antigen?
collecting channels that carry lymph from the lymph nodes to the veins
What are lymph ducts?
Located in the pharynx and traps pathogens entering through the mouth or nose
What are the tonsils?
Where the process of hematopoiesis happens
What is bone marrow
What is the right lymphatic duct?
Y shaped protein created by B-cell attaches and immobilizes pathogens so they can be phagocytized.
Lymphatic vessels help move fluid in this one direction
What is toward the heart?
The system of soft tissues is found in the mucous membranes and protects the mucosal surfaces
What is mucosa-associated lymphoid tissue?
Where B-cells and precursors are produced
These structures are found in clusters along lymphatic vessels and filter lymph
What are lymph nodes?
These types of vessels bring fluid toward a lymph node.
What are afferent lymphatic vessels?
Contains valves to prevent backflow of lymph
what are lymphatic vessels?
