I'm emphatic about Lymphatic
The characteristics of lymphatic vessels
Thin wall, valves to prevent back flow, thin layer of epithelial cells
T & B cells do what for the body
Protect against foreign invaders
The role of the mucus membrane of the respiratory tract
Physically traps pathogens
The largest lyphatic organ
Spleen
Enlarged lymph node
Lymphadenopthy
Where Immune cells recognize bacteria and other harmful substance - (they are throughout the body)
Lymph nodes
The body routinely makes its own antibodies or T cells against a pathogen.
Active immunity
What do Veins and Lymphatic vessels have in common
Valves
These cells that are important in immunity develop in the Thymus
T lyphocytes (or t cells)
When our body treats part of our own body as an antigen
Autoimmune disorder
Guard against pathogens entering the body through nose and throat
Tonsils
Possible to achieve immunity after receiving antibodies from another organism.
passive immunity
name a sign of inflammation.(there are many correct answers)
Swelling. Redness. Heat. Pain.
Substance capable of triggering an immune response
Antigen
The eyes produce what enzyme to protect against antigens (Bacteria)
Lysozyme
Known as the Gut-Associated Lymphatic Tissue (GALT)
Peyer's Patches
Directed against a specific pathogen
specific immunity
Group of proteins produced by cells as a "warning" of infection by a virus
Interferon
The human immune system can produce billions of different of these.
Antibodies.
This lymphatic organ gets smaller as we age
The Thymus
Thymus
Is the lymphatic system an open or closed system?
Open - it starts with a blind ended lymph capillary
They help our immune system causing cells to lyse (explode) by punching holes i the membranes of bacteria
Complement proteins
Name the lines of defense
External barriers, Nonspecific immunity, specific immunity
The key function of the lymphatic system
Immunity, absorption of fats, the maintenance of fluid balance
