Ch. 20 Lymphatic System & Immunity Flashcards
What is the Lymphatic System’s Purpose?
Regulate Interstitial Fluid Volume
What is Interstitial Fluid?
The Fluid Between Cells
What is the fluid outside your cells?
Extracellular Fluid that is made of two subdepartments: Plasma and Interstitial fluid.
What is the fluid inside your cells?
Intracellular Fluid
What are the Lymphatic systems’ tissues and organs?
Bone Marrow,Tonsils, Thymus, Lymph Nodes, Spleen, and Mucosa-associated lymphatic tissue
What do Lymphatic systems’ tissues and organs do and contain?
They all play an important role in immune response and contain lymphocytes, a certain type of white blood cell.
After Lymphocytes are produced in the bone marrow, where do they go?
They go to the Thymus
What are the Lymphocytes’ job?
Their job is to protect our immune system by being able to distinguish what is ours vs. not ours, self vs. nonself
What is Interstitial Fluid?
It is fluid that filters out of the bloodstream and is put between cells. It has to be circulated by Lymphatic vessels or there will be swelling.
What two sections are Lymphoid organs/tissues broken down into?
Central which is bone marrow and thymus, and Peripheral which is tonsils, spleen, lymph nodes, and mucosa-associated lymphatic tissue
What does bone marrow do for the Lymphatic system?
Creates Lymphocytes
What does the thymus do for the Lymphatic system?
It is the “basic training” for the lymphocytes, where they are tested to see if they are immunocompetent, or if they can distinguish self from nonself
What do the tonsils do for the Lymphatic system?
If any foreign antigen tries to have oral/nasal entry, it would encounter lymphocytes here
What does the spleen do for the Lymphatic system?
If any foreign antigen is found in the blood or is blood-borne, it would encounter lymphocytes here
What do the lymph nodes do for the Lymphatic system?
If any foreign antigen is found in any lymphatic fluids, it would encounter lymphocytes here
