|
single layer of endothelium. Closed-ended. In interstitial spaces
|
|
|
structure of lymph capillaries: thre are flaps that are like _______________ ____________. And filaments to _____ space ____.
|
one way doors so fluids get in, but can't get out. filaments to hold space open.
|
|
|
Fluid inside the lymph system is called _________. Outside the lymph system is called _________.
|
lymph. extracellular fluid.
|
|
|
lymphatic pathway
|
capillary>lymph vessel>lymph node> lymph vessel>lymph trunk>collecting duct>subclavian vein.
|
|
|
lymph movement (like in veins) list the 4
|
1. skeletal movement 2. respiratory movement. 3. smooth muscle in larger lymph vessels 4. valves in lymph vessels
|
|
|
there are collections of lymph tissue thru out the body: these are NOT ________-_____.
|
lymph nodes
|
|
|
function of lymph nodes name the 3
|
1. filter the tissue fluid
2. Immune surveillance (on the lookout for trouble.) 3. lymphocytes and macrophage proliferation. |
|
|
Name the location of the 7 lymph nodes
|
1. thoracic cavity 2. axillary 3. inguinal 4. cervical 5. supratrochlear 6. abdominal 7. pelvic
|
|
|
thymus is located in ___________ and makes __-lymphocytes. The thymus is ____ in infants, ____in children and _____ in adults.
|
thorax, T-lymphocytes, large in infants, smaller in children, and adipose tissue in adults.
|
|
|
Spleen does for the _____ what lymph nodes does for lymph.
1. 2. 3. 4. |
blood
1. filters blood 2. immune surveillance 3. removes old RBC's 4. is a little bag of blood. |
|
|
2 types of body defenses in immune system. Name them.
|
1. Innate and 2. Specific
|
|
|
Innate defenses: list the 7
1 S_____ R________ 2. M________ barriers 3. C_________ barriers 4. F 5. N________ K_______-cells 6. I_________ 7. P___________ |
1. species resistance (can't get kitty leukemia) 2. Mechanical Barries (skin) 3. Chemical bariers (lysosomes) 4. Fever 5. Natural killer cells (make perforin 6. inflammation (barrier to spreading infections) 7. Phagocytosis (removes particles from lymph and blood).
|
|
|
Specific body defense: 2 types
|
T-cells
Antibody response (B Cells) |
|
|
B cell is activated by presence of ______. B cell becomes a ______ cell and makes ________.
|
antigen. plasma cell, makes antibodies.
|
|
|
types of antibodies
lgM lgG lgA lgE lgD |
lgM-1st responder
lgG memory lgA found in secretions/breast milk lgE allergies lgD is a B-cell receptor and aid in its activation. |
|
|
classification of immunity
Active/passive and Natural/artifical 2 ?'s 1. who makes it? 2. how did process happen. |
who makes it? you-active. someone else-passive
How did process happen? natural or artificial-medical intervention (U got a shot).vaccination is artificial but active. (hep A ex. in class artificial and passive because someone else gave U the antibody and someone else made the antibody) breast feeding: natural, passive |
|
|
allergy is an ________ immune response to something that is not ________. It is your own immune response (massive amounts of histimine that make you sick)
|
inappropriate, not harmful
|
|
|
tissue rejection happens because the tissue is not ____.
|
self, it has markers just like RBC's.
|
|
|
Helper T cells present the T-cell with an ____ and tells the T-cell to ______ and tells self to ______ as well.
|
antigen, replicate, self replicate as well.
|
|
|
Polyclonal response
|
the antigen has many receptors so it activates an antibody for "a square", a "circle" a triangle and many others, and all those activate their own antibody and it clones itself many times.
|
|
|
Antibody actions 4 kinds
1. D___ A_____ 2. N________ 3. O_________ 4. C_________ |
1. Direct attack-clumping
2. Neutralization (like putting a cap on the dangerous part so it's not a danger anymore. 3. Opsonization - coating the antigen so its easier to see and macrophage can eat it. 4. Complement-proteins that poke holes in cell membranes (like perforin w/ T cells) |
