.: Immunology:.

Summary:
Immunology is the study of the immune systems structure, functions, disorders, and organ transplantation. This chapter is about the immune system and the types of immunity that we have to things around us. On a daily basis we can run into pathogens but some don't hurt us like others do, because he have become immune to them. Whether it was a vaccination on our bodies produced memory cells to recognize that pathogen so we don't get sick. The immune system is a very complex system with white blood cells that fight against the pathogen we encounter.

How will Immunology help me in the work place?
I will be working in a hospital setting, and eventuality I will probability give vaccination of some sort. The chapter will help me understand just what and why I'm giving that vaccination to my patient. It will also help me understand the importance of keeping healthy and understanding disease that are out there like auto immune diseases and allergies. Immunology will help me explain to people just why there bodies are having the response to either pollen or a simple thing like a bee sting.Diseases of the immune system:Immune system

This you tube explains how pathgens are transmitted and what kind of immunity fights against the pathogens:



Active immunity- Immunity that comes from your own immune system.

-Causes the development of B- cell clones that can provide a secondary response.

-developement of a secondary response = active immunity
vs.
Passive immunity- The person doesn't make the antibodies by its own immune system.

-Immunity that stronger because of a donor transfer antibodies to the recipient.

- happens before and after birth
Innate immunity-inherited genes

- treat all pathogens the same
vs.
Adaptive immunity- Occurs over time

- specific features of pathogens are reconized
produces genetic changes in lymphocytes

- only produced when a pathogen come in contact and need to be destroyed
Cell-Mediated immunity-Actively getting rid of pathogens.
vs.
Humoral immunity- seeps into blood and produces antibodies.
This is what happens when an allergic reaction occurs. Picture 2 is natural and active immunity:

Describe the process of a local inflammatory response.

Local inflammatory response occurs when there is a break in the skin. This is where the pathogen enters the body. The inflammatory reaction is started by the nonspecific mechanisms (phagocytosis) and complement activation. Complement activation is a red flag and attracts phagocytes to the area that is being invaded. Later B cells produce antibodies to fight against the pathogen. The attachment of antibodies to antigens heightens the nonspecific responses and promotes phagocytic activity of other white blood cells( neutrophils, macrophages and monocytes). once this happens the pathogen until it is destroyed. The inflammatory response that we can see is edema, swelling, warmth and redness

This is where local inflammation would occur: 2 days after the abrasion occurred

Fun Fact:The average human body contains enough: iron to make a 3 inch nail, sulfur to kill all fleas on an average dog, carbon to make 900 pencils, potassium to fire a toy cannon, fat to make 7 bars of soap, phosphorous to make 2,200 match heads, and water to fill a ten-gallon tank.
