Lymphatic system Flashcards
A specialized fluid formed in the tissue spaces and transported by lymphatic vessels
Lymph
Five structures of the body that make up the lymphatic system
Nodes
Nodules
Spleen
Vessels
Thymus
Describe the movement or flow of lymph
One way
To terminal vessels of the lymphatic system
Thoracic duct and right lymphatic duct
Lymphatic vessels have a beaded appearance caused by ______ that assists in maintaining the flow of lymph
Valves
An enlarged pouch-like structure of the lymphatic system
Cisterna chyli
Lymph is filtered by the structures
Nodes
Lymph from the right upper extremity, and from the right side of the head, neck and upper torso flows into this
Right lymphatic duct
Part of the lymphatic system located in the mediastinum
Thymus
Parts of the lymphatic system that is important in the maturation of specialized lymphocytes
Thymus
T-lymphocytes, specialized lymphocytes that circulate in the spleen, tonsils, and lymph nodes are developed here
Thymus
Moderate exercise increases or decreases the immune system
Increase
Strenuous exercise increases or decreases the immune system
Decreases
They help protect against bacteria that may invade tissues in the area around the openings between the nasal and oral cavity’s
Tonsils
The largest lymphoid organ in the body
Spleen
This organ holds 1 pint of blood for future needs
Spleen
This organ removes (via filtration and phagocytosis) many bacteria and other foreign substances
Spleen
This organ destroys worn out red blood cells
Spleen
Once red blood cells are destroyed, this organ salvages the iron found in hemoglobin for future use
Spleen
The name for the removal of the spleen
Splenectomy
A breast fed infant is receiving an active or passive immunity?
Passive
A child has just had an inoculation. He has received an active or passive immunity.
Active
Two types of protein molecules that are critical to the immune system functioning effectively
Antibodies and compliments
These are proteins compounds that are normally found in the body; produced to suppress or destroy antigens
Antibodies
Three phagocytes of the immune system
Neutrophils monocytes macrophages
Two types of lymphocytes
T cells & B cells
Two primary cells of the immune system
Phagocytes & lymphocytes
Once, in the tissues, monocytes develop into these phagocytic cells
Macrophages
And some of these phagocytic cells are like police officers; they patrol through the tissues to engulf bacteria wherever they find them
Macrophages
Macrophages found in the spaces between liver cells are called
Kupffer’s cells
Macrophages found in the small air sacs of the lungs are called
Dust cells
These are the most numerous cells of the immune system
Lymphocytes
These are cells responsible for antibody production
Lymphocytes
