January 25th 2016 Epidemics and AIDS Homeostasis complete balance Our health depends on what we eat our behavior and our feelings If our hormonal system comes out of balance it can throw everything in your body off We can take care of these things by taking care of our emotional health properly Questions she asked for revision What s an epidemic What s a pandemic What s an endemic What s a cell What s a eukaryotic cell structure CDC Center for Disease Control This institution collects all kinds of information all over the country and they do their own statistics and you can plug into said statistics so you can see what s going on in your area and any other area in the country General information for general public Scienti c information which is limited to the scientists and the medicals Prokaryotic cells have a very distinct structure Morphology structure of any cell ology study The bacterial cell wall is very thick because it has a very plump sugar This is where antibiotics work Antibiotics will break the sugar cell walls and the bacteria will die Antibiotics are not risk free because they will also kill your normal cells as well Bacterial cell also has nucleus the DNA sits inside but this nucleus isn t visible because it s embedded in the cytoplasm Antibiotics only work on bacteria not on virus Prokaryotic before nucleus There are many types of bacterias Bacterias that cause disease are called pathogens Pathology the study of pathogens Some are round and they are called coccuscocci Other are rod shaped and they are called bacillusbacilli Lastly there are spiral they are called spiral or spirulum There are good bacterias too Bacterias are important for our lives as well Cheese silk wine yogurt All of these things need bacteria Probiotic inoculating bacteria to your gut infusing bacteria that will generate in different kinds of food Not fond of probiotics because the best way to generate good digestion is to enhance your OWN bacteria instead of introducing new bacteria into your body Also bacteria called symbiotic bacterias they are very important because they aid into our food chains Legumes have bacteria that stays in their roots what they do is absorb nitrogen from that plant and make it an essential food for their own survival This also fertilizes the soil Virus derives its name from the roman word poison It s a noncellular kind of a structure Virus NEED to grow in a host It will NOT survive or grow by itself They are kind of a parasite they cannot generate by themselves Caspid very thick protein coat Inside there will be DNA or RNA It needs a hosts DNARNA to manifest its own They are very tiny particles smaller than bacterias they cannot be seen even under microscope Since their protein wall is so strong the antibiotics won t work on them We call the virus either DNA or RNA virus they are split into two subdivisions Within the protein coating they will have enzymes and etc but not DNA or RNA Ex of DNA virus Pox EBV Not able to make RNA unless it gets into the host Ex of RNA virus Myxovirus retrovirus rubella Not able to make DNA unless it gets into the host The immune system is your bodies defense mechanism As a system we have everything in our body body is a very beautiful mechanism of nature and no body cures us the body cures itself The medicine that we take only aids into that healing but healing is done by your own body The immune system is defending the body from ANY incoming processes that could be harmful to you Food is the most arti cial thing that comes into our being our immune systems is also very good friends with our stomachs Two kinds of immunity Innate immunity the immunity that we are born with Adoptive or Acquired immunity we are adopting the system by immunizing ourselves building up tolerance through exposure Autoimmune diseases when your own immune system is attacking yourself Our blood cells are called immune cells Blood cells are connective tissues the function of them is transportation oxygenation transport nutritionist and other things stabilizes pH balance keeps body temperature in check and ghts infection Two kinds of blood cells red and white CBC Complete blood count Different kinds of white cells these are called neutrophils lymphocytes monocytes and macrophages esonophil and basophil THESE WILL BE ON THE EXAM In grown ups they are generated in the bone marrow Inside the stem cells can generate different kinds of cells Bone marrow is the primary immune organ it can give birth to all of these cells Lymphocytes are of two types one type will be B cells the other type of lymphocytes is called Thymocytes these thymocytes have to go to the Thymus to mature this journey is called homing In Thymus with the help of thymus hormones they will transform into t cytotoxic TC or t helper cells TH The generation of all of these cells is called ontogenesis If she asks about ontogenesis this is what we will be giving her Lymphocytes B cells nutrophils monocytes MO Esonophil Basophil gt Plasma cells gt Antibodies Phagocytosis is when macrophages engulf the foreign particles the projections are called pseudo pods Antibodies will hit incoming particles and destroy them 5 different types of antibodies IgG IgM IgA IgD IgE gee G made is an easy way to remember it When babies are in gestation they get IgG from mothers placenta into the babies system That is the rst defense mechanism that mother disposes to the child The second line of defense comes from breast milk which is very very rich in IgA and IgM in very small quantities Baby is still not making its own immune cells because the Thymus doesn t exist in babies it doesn t develop until around ages 7 8 then the thymus disappears by the time you re 17 19 Your immune system is already made for your entire life by the time you re a young adult You must maintain yourself by taking good care of your body good food good behavior good lifestyle Humoral immune system plasma cells and antibodies Cellular immune system Thymus TC and TH Cytokines are immune hormones and all of the cells make different kinds of cytokines but the T Helper cell Will make an array of cytokines and that array of cytokines Will help the entire immune system If you kill the TH cells the immune system is almost dead because there s no stimulation left Active immunity When you are infected yourself you body defense mechanism recognizes the array of invaders coming into your system and they make memory cells so the second time the infection comes they are prepared to attack Passive immunity When the immunity is acquired from outside Vaccines put a little bit of virus inside of you and the memory cells become eXposed to the incoming pathogen When it comes again they recognize it and kill it No vaccine is 100 safe or guarantees you Will not have infection However Even if you have the infection it won t be as severe if you have the vaccine Never fool proof but it Will guarantee the activity and strength of your memory cells Your body is usually prepared and kills most invasions immediately before symptoms even arrise Ig immunoglobulin Homework Reproduce the ontogenesis chart WILL BE QUIZED ON THIS
