Lymphatic and Immune System Kyle Dizon P.2
Disorders of the immune system
Sepsis - The inflammatory response that is uncontrollable in which the defenses are very delicate and fragile leading to issues with immune system responses.
Systemic lupus erythematosus - Disorder found in females that is an issue in the autoimmune system that damages kidneys, blood vessels, brain, and synovial membranes.
Hashimoto's thyroiditis - disease that both B and T lymphocytes attack the thyroid gland.
Antigens and antibodies
Y - shaped proteins that helps the body fight the foreign substances.
Substances that signal the creation of antibodies that is a foreign substances such as viruses, bacteria, etc.
Humoral vs. cellular response
T-cell recognition abnormal surface host cells that kill infected kills.
Involves B cells that recognizes and binds with antigens and antibodies. Enhances the creation of B cells.
Innate/natural immune defenses and Adaptive/acquired immune defenses
Innate - nonspecific immunity that is associated with anatomic barriers, inflammatory barriers, and phagocytes. Also have rapid response along with pattern recognition.
Adaptive - slow response with memory and recognition that response B and T cells. Creates defenses for specific targets to kill.
Anatomy of lymphatic system
Thymus which T lymphocytes grow to enhance the protection and responses of our bodies to fight pathogens.
Mucosa-associated lymphoid tissue that protects the body from pathogens in which it consists of tonsils, Peyer's patches, and appendix. The tonsils is in the throat that gather and remove pathogens that are invading. The patches form a wall near the small intestine. The appendix prevents bacteria to enter the wall of patches and create memory cells to fight pathogens.
Spleen which is the large organ of the lymphoid system that allows immune surveillance and response to occur. It also cleans, recycles, and stores the blood. It has the components of both white and red pulp
Lymph Node which is a defense mechanism that is surrounded by capsules from trabeculaes which also has the regions of cortex containing follicles dividing B and T cells. The other region of medulla that has medullary cords.
Major functions of the lymphatic and immune system
Protecting the body from invaders (pathogens) such as viruses and bacteria's and many more.
Contains networks of tissues and organs to remove waste toxic.
Remove wastes in the body and prevents invading pathogens to enter the body.
Contain white blood cells and bring it to the body which also improves the body's ability to response against invaders.
Transport lymph and fluids throughout the networks of the body
