Cells of the Lymphatic System
These are the three types of lymphocytes in alphabetical order.
What are B-cells, NK cells, and T-cells?
B cells = antibody production
T cells = defend against disease & control immune response
Natural killers = attack infected and abnormal cells, secrete perforins
What are lymphocytes?
The lymphocytes have the ability to recognize specific invaders and then take appropriate measures to protect the body
Physical (intact), Mechanical, and Chemical
What are the three types of barriers in the first line of defense?
extra: give an example of each
Innate (nonspecific) defenses deny pathogens access to the body or destroy them without distinguishing among specific types
These are the 4 forces that propel lymph through the lymphatic vessels.
What are the Abdominal pump, Respiratory pump, Skeletal pump, and Valves.
Forces that move blood in veins (skeletal muscle, contraction, breathing movements, and contraction of smooth muscle in the walls of vessels) are also the forces that propel lymph through lymphatic vessels
The 3 important lymphatic organs.
What are the lymph nodes, thymus, and spleen?
These are the types of cells in which MHC ll molecules are expressed.
What are antigen presenting cells?
B cells, macrophages, dendritic cells
These are the 4 primary types of T cells arranged in alphabetical order.
What are Cytotoxic T cells, Helper T cells, Memory T cells, and Suppressor T cells?
All types of T cells work together and coordinate for specific defenses.
Cytotoxic T cells attack, helper T cells aid in activation of the cells, memory T cells respond to antigens previously encountered, and suppressor T cells moderate the immune response by releasing chemicals to calm the situation.
The four qualifications for inflammation in English and Latin.
What are Redness (Latin rubor), Heat (calor), Swelling (tumor), and Pain (dolor)?
These are what make the structures of lymphatic capillaries different from blood capillaries.
What is a larger diameter size and closed ends?
Lymph capillaries are slightly bigger and have fibers that allow them to close off one end that allows interstitial fluid to flow into but not out of them
The area where the spleen is located.
What is the upper left abdominal cavity?
(Left Hypochondriac Region)
These are the amounts of fatty tissue in the thymus ranked in age from most to least.
What are old, adult, child?
These are the 4 properties of adaptive immunity.
What are Memory, specificity, tolerance, and versatility?
Memory refers to the ability to remember antigens, specificity is the activation of appropriate lymphocytes, tolerance is not responding to all antigens, and versatility is the readiness to encounter any antigen at any time.
A rise in the level of interferon in the body are a sign of this kind of condition.
What is a viral infection?
Interferon does not help an infected cell, but “interferes” with the replication of the virus and thus the virus’s ability to infect other cells
These are what make lymphatic vessels similar to veins.
What are the three tunics and semilunar valves?
Have the same three layers in their walls and valves that prevent backflow
Create antibodies when prompted.
What are B cell?
Extra: who instructs the B cells to create antibodies?
The three types of cells housed in the red pulp of the spleen, in reverse alphabetical order.
What are Macrophages, Lymphocytes, and Erythrocytes?
This is what results after the activation of a complement.
What are opsonization, chemotaxis, inflammation, or lysis in target cells or antigens?
Created in the brain to insight a fever.
What are pyrogens?
extra: what part of your brain do they affect?
This is done by stimulating the temperature control area of the pre-optic nucleus of the hypothalamus.
When you get a scrape on your right knee, lymph would drain into this lymphatic duct.
What is the Thoracic Duct?
The thoracic duct collects lymph from the body inferior to the diaphragm and from the left side of the body superior to the diaphragm. The smaller right lymphatic duct collects lymph from the right side of the body superior to the diaphragm.
translates to “Large Eater”
Predecessors were originally created in the fetal liver and then the bone marrow.
What are macrophages?
Extra: Where do their predecessors rank in terms of abundance?
The lymphocytes released from bone marrow during fetal development mature into, placed in order, from highest percentage to lowest.
What are T cells, B cells, Natural killers?
70-80% become T cells
25% become B cells
5% become NK cells
Known as the four types of acquired immunity.
What are Artificial active, artificial passive, natural active, and natural passive immunity?
Artificial active occurs from a vaccine, artificial passive would be from a seasonal shot, natural active would be exposure to antigen, and natural passive would be passed from mother to child.
This type of interferon attracts and stimulates NK cells as a way to enhance viral resistance to viral infection.
What is interferon Alpha?
This drives the entry of lymph into lymphatic capillaries.
What is Hydrostatic pressure of tissue fluid?
What occurs when two non-matching blood types interact.
What is agglutination?
