-
lymphatic cells
floating around the body to see if we have any invaders
-
lymph nodes are
holding space for the invaders
-
Invaders are
bacteria, virus, fungus
-
why do do we get invaded.
because our body is warm, dark and moist
-
Promote growth and development of lymphocytes
bone marrow,lymph nodes,lymphatic vessels, thymus, spleen, tonsils, appendix, blood(transports)
-
bone marrow does
creates cells
-
Lymph nodes do
hold lymph cells and invaders
-
Lymphatic vessels do what
passageways for lmphatic fluid
-
What is Major Histocompatibility Complex (MHC)
- It is in each in every one of your cells
- -Individual DNA marking in cells
- -Allows cell to recognize and communicate with each other
- - Allows cells to recognize any cells with our markings
- - Creates your immunities
-
*The invaders cannot communicate with you that’s how they know they are a invader. Our cells can only speak a certain language…. They attack them and Then they take em to the the lymph nodes. The lymph nodes swell because they r filling up with the invaders.They swell in the area where the infection is. Then they get all types of information to kill em.
Purpose of MHC
-
What is able to remember encounters with foreign cells and record how to respond
immune cells
-
Types of lymphatic cells
lymphocytes,bcells, t cells
-
lymphcytes are
white blood cells
-
formed from stem cells and hold the antibody markers for future encounters with invaders (they actually make your antibody)
Will divide to create “clone” antibody cells
b cells
-
directly interacts with unwanted cells
-Assists with cellular immunity
t cells
-
helper t cells
they activate b cells
-
attacks infected and malignant cells
Cytotoxic T
-
what is da disease that now works with the body
antibodies
-
types of lymphatic cells
intergeron, natural killers (nk), cytokines
-
intergeron
fights viruses
-
natural killers (NK)
type of lymphocytes that targets tumors and contain deadly chemicals
-
cytokines
– regulate immune response -Encourage cell growth -Gathers info from other cells
-
The greatest concentration of lymph nodes are where
in the openings of your body
-
allows fluid to enter the lymph node
afferent lymphatic vessel
-
– exit the lymph node
Efferent lymhatic vessel
-
Immunoglobins are called
antibodies
-
that enter lymph nodes to “ remember” invaders and response
antibody compley cells
-
– guards the entrances of the body ( anus, penus, vagina, ears, nose, eyes,mouth)
IgA
-
IgD
regulates cell activities
-
IgE
triggers allergic response
-
IgG
coats organisms to speed up immune response
-
-
immune response
an invasion
-
Recognition of the invador
Growth of defenses
Attack of invaders
Decrease immune response after death of invader
invasion
-
(sensitivity) to substances in your environment – pollen, cat hair
allergic responses
-
-Hypersensitivities to environment
-igE is triggered
-effects skin, lungs and nasal
allergic response
-
actual invasion to your body
pathogen responses
-
two types of immunity
artificially acquired and naturally acquired
-
immunity after shots given
Vaccines – cause the porduction of antigen antibody complex and memory cells
Ready made antibodies – temporary treatment used to prevent diseases
artificially acquired
-
immunity after contracting disease
Active Immunity – a result of infection
Congenital immunity – immunity passed from mother to fetus or mother to infant through breast milk temporary immunity
naturally aquired
