Lymphatic System Flashcards
Lymph that flows into vessels
AFFERENT vessels
Lymph that flows out of vessels
Efferent vessels
Walls of lymphatic capillaries contain
Fatten adipose tissue
Which cells produce antibodies
B cells
Cells that destroys directly
Killer T cells
Cells that stimulate other cells
Helper cells
Chemical
Non Specific
B cells
Specific
T cells
Specific
Inflammation
NonSpecific
Nonspecific is also known as
Inate
Specific is also known as
Adaptive
Which ways do lymph move?
Muscle contraction, massage, compression, breathing, and smooth muscle
Lymphocytes multiply lymph nodes
True
Lymph nodes that are in shoulders and armpits?
Axillary
Breast lymph nodes
Mammary
Lymph creates absorption of fat
True
The spleen serves as a reservoir for blood and produce red blood cells before birth.
True
Left thoracic duct
Lymph lower extremities
Right thoracic duct
Lymph upper extremities
T cells are regulated by which gland?
Thymus
What are lymph chemical and mechanical barriers?
Skin, mucous, cilia and sweat
Lymph tissues
Adenoids, palatine, label & tonsils
Immunity that involves production of antibodies and memory cells by the individual is termed
Active immunity
Immunity acquired as a result of the transfer of antibodies to an individual from outside source
Passive immunity
Three functions of the lymphatic system?
Fluid balance, protection, and absorption of fats
The vessels are very permeable, permitting the passage of large proteins
Lymphatic capillaries
Lacteals are one example of this type of vessel
Lymphatic capillary
Fluid moves from the interstitial space into lymphatic capillaries by the process
Bulk flow
A ____ gradient promotes fluid movement into lymphatic capillaries
Pressure
The concentration of proteins in lymphatic capillaries are ___than protein concentration in the interstitial fluid
Less than
An area of lymphoid tissue specifically found in small intestinal wall
Peyer patch
The indented area of a lymph node where efferent lymphatic vessels exit the node
Hilum
An oval lymphoid body located at the side of the soft palate
Palatine tonsil
Lymphoid tissue associated with mucous membranes, such as the tonsils and appendix
MALT
A granular leukocyte that participated in inate defenses
Neutrophil
A cell that reduces an immune response by inhibiting of destroying activated lymphocytes
T reg cell
Produce substances that cause the cell to “ self destruct”
Cytotoxic t cells
The type of B cell that produces antibodies
Plasma cell
The type of B cell responsible for the secondary immune response
Memory b cell
A set of blood proteins that carry out many different immune activities
Complement
Two types of white blood cells in lymph nodes are
Macrophages and lymphocytes
The internal structure of lymph nodes include:
Reticular fibers, macrophages, and lymphocytes
Protect the body from all foreign invaders regardless of type or location
Nonspecific defenses
First line of defense that includes mechanical barriers such as skin and mucous membranes
Nonspecific
Secrets acid or enzymes to inhibit bacterial growth
Mucous membranes
Small proteins secreted by virus infected cells that protect other cells nearby from being infected ?
Interferons
Two divisions of the immune system
Humoral and Cellular
Antibody-mediated immunity
Humoral
Cell mediated immunity
Cellular
Antibodies are also called
Immunoglobulins
