Ricky Garcia-Period 7- Lymphatic/Immune system
innate (natural) immune defenses and Adaptive(Acquired) immune defenses
Natural:
This Defense system is what you were born with.
It involved barriers such as the First line of Defense- Or skin to keep harmful pathogens out of your body.
Acquired:
When a person's Cells react to a foreign substance or pathogen it acquires a form of knowledge that helps the Body remember this specific pathogen if it ever invades again. These are called B cells.
Location of Lymphatic organs and their Functions
Thymus: Near the Thoracic Cavity, located behind the Sternum; The Tymus serves by providing protection against pathogens, antigens, and Tissue Damage.
Spleen: The Spleen is located in the Abdominal region Superior to the right of the Appendix. The Function of the Spleen is to clean out blood and to be a storage container for Platelets, Monocytes, and Iron.
Malt: Malt protects against pathogens and can diffuse lymphatic tissue.
Lymph Nodes: Located in most regions of your body from the pelvic area, to the armpit area near the thoracic cavity. The purpose of Lymph Nodes is to clean the Lymph and act as a site for lymphocyte activation.
Passive vs. Active immunity
Active Immunity: When our body must rely on itself to protect us from pathogens and other deadly diseases that could cause us bodily harm.
Passive Immunity: Passive Immunity is a process that occurs when the protection is given to us.
Example: A mother gives Antibodies to a baby before birth and the child is born with the Antibodies against the Virus. The baby will have Immunity for a short duration.
Humoral response and cellular response
Humoral Response: Produces Antigen specific Antibodies to fight a certain pathogen.
Cellular Response: Antibodies produced by this Response are non specific and attack anything foreign within the general vicinity.
Antigens and Antibodies
Antigens: Large Molecules that trigger immune responses.
Before Birth, They create "Self-Antigen" Which helps detect "non-self" Antigen so that the pathogen can be attacked and dealt with.
Antibodies: proteins that are produced by the body to deal with a specific Pathogen.
Purpose and examples of First,Second, and Third line of Defense.
Second Defense: The second line of defense consists of non-specific immune cells like macrophages and dendritic cells.
Third Defense: The Third line of Defense would be considered the last and it consists of B cells And Killer T cells which all attack a specific target.
First Defense: Skin,Sweat, Mucous Membranes which all act as a physical Barrier against pathogens and there foreign objects.
Artificial vs. naturally acquired Immunity
Active Immunity: Active immunity is gained either through exposure to an Antigen which can lead to long term resistance.
Another way is by the use of vaccines which is the process of injecting a weakened or dead version of the virus so memory B cells can be created.
Passive Immunity: Passive immunity can be gained through pregnancy and through injection of gamma Globulins that contain antibodies.
Both of these do not cause long term immunity.
Disorders associated with the Immune system.
Autoimmunity disorder- Makes Antibodies turn against its own Antigen which damages Bodily tissues.
Can come from Viral infections or faulty T-Cell production.
An Example of this would be Type 1 Diabetes since Insulin is produced but destroyed by the bodies AutoAntibodies since the insulin cannot be recognized.
Major Functions of the Lymphatic & Immune system
Lymphatic: The Lymphatic system is responsible for maintaining the bodily fluids that reside in the system, as well as removing Cellular Waste and keeping fluids such as blood and lymph clean.
Immune system: The immune system is similar to a surveillance system by keeping an eye out for invaders while also keeping them out using a set of defenses to protect us from pathogens.
The immune system also has the Ability to memorize certain pathogens so in the event the same one invades or a strand that it can recognize, the immune system will be able to defend us.
Cells involved in the Immune system and their functions.
2nd Defense Cells:
neutrophil: Trap and Kill the Pathogen
Mast cells: Control the different Immune responses
Macrophage: Attack pathogens on the front line.
Dendritic Cells: Boosts immune system responses.
3rd Defense Cells:
T cells: Help fight pathogens and protect the body from infection.
Helper T cell: Activate B cells and Release Antibodies.
Helper B cell: Cytokin Production
Killer T cells: Only purpose is to kill and die after to avoid hurting the body
