BSC 160 1nd Edition Lecture 26 Outline of Last Lecture 1. Immunity Continued…2. Self vs. NonSelfOutline of Current Lecture 1. Immune System2. Lymphatic System3. Inflammation Current LectureImmune System Basics- Immune Cells- Oxygen carrying. Can create up to 8 cells- Mejakaryocyte- Role in innate system- Platelets- clot formation- NLMEB- Nutrifills- fagositic Lucacytes- B & T Cells - B Cells- Memory cells (previous exposure)- T Cells- Regulation of immune responseMonocytes Emonofils Basafills - Related to Mast Cells- Related to unallergic responsesLymphatic System- Separate vascular systemThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Not part of circulatory system- Starts in dead end capillaries. Areas that are first place to find invading pathogensFunctions- Role in returning excess fluid back into cardiovascular circulation- Absorbing fat. Lactilles- Moves immune cells throughout bodyLymph Fluid- Pushed out at arterial end at capillary system and not absorbed. Mostly Plasma, white blood cellsMALT- Moist epithelial tissueWhite pulp- Lymphocytes; monitoring liquids in our bodyPeople without spleen- more susceptible to infection over lifetimeAdaptive- Antibodies, cell mediatedInnate (Nonspecific Immunity)- Provides general reactions to potential in pathogenic invasion. Nothing specific in response, Preventing colonizationBody fluids- have chemical barriers to protect from pathogensComplement System & 3 pathways- know big picture1. Classic pathway- 2. Lectin pathway-3. Alternative pathway-NK Cells- Natural killer cells, perfornisPoke hole in pathogen- Protect against viruses & cancer- ApoptosisInflammation- Response to anything disrupting immune system. - Heat- Redness, swelling, pain- Loss of function
