Innate Immunity Research Paper

The immune system depends on the body’s structures to help it function. For instance, the skin acts as the “body’s first line of defense.” If a pathogen finds a breach in the skin barrier, it is the circulatory system that must now signal the immune system of the invader. Shortly after, white blood cells will be notified of the infection and will target and destroy the pathogen.

The innate immune system is effective to a certain degree. That said, if the environment is regulated then the body is less likely to get ill. Innate immunity is effective as once the patient matures his immune system will mature due to the B and T memory cells. The memory cells will help the body prepare for the virus once it has arrived. The memory cells will send specialised lymph nodes to the invading pathogen. The B and T memory cells are key to immunity of a virus.

The body’s protection against viruses, bacteria and other types of invasions is our immune system (Tortora, 2014).

Innate Immune System – Nonspecific and abrupt first response; comprised of epithelial surfaces (physical barriers), neutrophils, and macrophages.

Defense mechanisms are said to be specific because depending on which one they focus on one specific part of the body or a specific type of pathogen.

Background: Innate immunity is the first line defense against invading microbes pathogens. Human blood is full of cells that express immune system such as Neutrophils. The most important operation that Neutrophils do in this lab is phagocytosis. Phagocytosis is normal reaction white blood cells doing when human body is under attack from bacterial pathogens.

The Innate Immune System and Pattern Recognition Receptors – The innate immune system, which is also known as the non-specific immune system, is an important component of the immune system that recognizes and responds to potential pathogens in a “generic” fashion. In contrast to the adaptive immune system, the innate immune system does not confer long lasting/protective immunity. The innate immune system is typically considered the first line of defense and displays the ability to discriminate against “self” (host) vs. “non-self” (non-host/potential pathogens). In order to recognize non-self molecules the innate immune system utilizes a range of pattern-recognition receptors (PRRs) to detect molecules associated with potential pathogens.

The immune system consists of a defense system that guards the body against invasion from infections and other diseases. Normally, a healthy person's immune system has the capability to differentiate between its own cells and cells that represent threats to the health of the body. (Craft and Kanter, 2002). Autoimmune disease refers to a broad range of over 80 acute, long-lasting diseases that affect nearly every organ in the body. (Wrong Diagnosis.com, 2000).

The first line of defense include structural, mechanical and chemical defenses. Structural defenses that people have are their skin, since the skin it’s dry it doesn’t allow bacteria to survive in the skin. It also doesn’t allow pathogens to enter the body. Mucous membranes also help fight back disease by the cilia grabbing into particles and trying to take out anything when your sneeze. The normal flora is another way we fight pathogens. The bacteria that are in our system push out the pathogens and they can also release acids that some pathogens may not like. Some mechanical ways our body protects include movement of bodily fluids. When we urinate we can flush out bacteria. Other mechanical ways are by our body releasing tears and saliva.

Innate immunity refers to antigen-nonspecific defence mechanisms that a host uses immediately or within several hours after exposure to an antigen. This is the immunity that you are born with, and is the initial response by the body to eliminate

Normally the body is protected by the immune system. When the immune system detects an unwelcome visitor such as fungi, bacteria and or viruses

The immune system is comprised of two responses: the adaptive immune response and the innate immune response. The first line of defence against invading organisms is classified as the innate immune response and the second line of defence and protection against re- exposure to the same pathogen is known as the adaptive immune response.

The human body is a complex system, embedded with defense mechanisms to prevent the invasion of the unknown. Not only does it protect itself from the external breaches, but also has to beware for all the potential things that can go wrong within the system. When a potential threat is detected, a trained army of cells will immediately reach the site and work towards achieving balance; this is called immunity.

Have you ever wondered how your body works? Did you ever think about how your body defends itself from outside invaders? Remember the last time you were sick. Did you know how your body fought and killed the sickness? All these questions can be answered by learning about one of the most important systems in your body, the immune system.

Our immune system is made up of two parts that work together to keep us healthy. The first part is called the innate immune system, it is made up mostly of ‘scavenger’ and ‘killer’ cells that fight off bacterial infections and give the body a general defense against harmful substances. The second part of the immune system is called the adaptive immune system. This part
