There are 3 barriers of protection
1st barrier is called the physical barrier
This includes:
·Skin
·Hairs
·Mucus
·Tears
2nd barrier is to heal the wound/cut as quickly as possible
This includes
·Scabs
The 3rd barrier is called white blood cells
This includes
·The white blood cell Phagocytes
·The white blood cell Lymphocytes

∙ 13y agoThe immune system fights off the pathogen by Leukocytes also known as white blood cells. When a pathogen enters the body the immune system becomes alert to it and sends out sends out the Phagocytes (a type of Leukocytes) which engulfs the pathogens. If the body has a weak immune system, the pathogens eventually overtake the body which can result in a disease. Some diseases as AIDS (Acquired immune deficiency syndrome) caused by HIV (Human immunodeficiency virus) may cause weakening of immune system.

∙ 14y agoThere are three ways :)
Phagocytosis Humoral response And Cell Mediated response
Phagocytosis involves Phagocytes , phagocytes become attracted to the pathogen due to the pathogen inadvertently releasing chemoattractants, the pathogen binds to the surface of the phagocyte, next the phagocyte engullfs the pathogen using its psuedopods ( 'arms' created from membrane) and is now called a phagosome ( pathogen within a vesicle/vacuole) Lysosomes within the phagocyte migrate towards it and fuse with the phagosome.Lytic enzymes within the phagocyte digests the pathogen and the soluble products are absorbed by the phagocyte,waste products are egested by exocytosis.
Cell Mediated response - Involves cells that have been invaded by pathogens- T lymphocytes are involved-type of white blood cell
A pathogen invades a body cell such as a phagocyte and its antigens presented on its surface as a sign of distress - T cells with complimentary receptors to the antigen bind to the antigens on the antigen presenting cell , this activates the T cells to divide by mitosis, Cloned T cells will either kill infected cells by creating holes in their membranes/Stimulate phagocytes to proceed with phagocytosis/Stimulate B cells to divide ( type of white blood cell) or simply circulate the blood as memory cells for the response of the invasion of the same pathogen at a latter date.
Humoral reseponse- Involves fluids such as blood plasma invasion of pathogens - Involve B lymphocytes- Type of white blood cell
A pathogen is engulfed by a B cell and its antigens presented on the surface of the B cell. A T helper cell which has complimentary receptors to these antigens bind with an antigen which stimulates the B cell to divide by mitosis. Clones will either become Memory or plasma cells. Plasma cells will produce Antibodies which will attach to the pathogen and destroy it, this is the primary response.
Memory cells circulate in the blood in readiness for a future invasion of the same pathogen.When the same pathogen does invade again memory cells are stimulated to divide into Plasma cells and produce antibodies to destroy the pathogen again- This is the secondary response. Hope that helps :) && was what you were looking for.

What colorless blood cells protect the body from disease?
the white blood cell protects the body against invading pathogens.
What is toxoid?
Toxoids are inactivated toxins from pathogens. They are used to stimulate the production of antibodies. Though many pathogens are not harmful themselves, the toxins they are produce cause sickness. Toxoids can be used to protect the body against such illnesses. Both tetanus and diphtheria immunization use toxoids.
What is the difference between pathogens and opportunistic organisms?
Pathogens infect the body when it is in good health while opportunistic organisms infect the body after it has been compromised.
What is the function of the respiratory mucosa?
As with all mucus in the body, its a lubricant to keep the lungs moist, prevents the lung lining from sticking to itself and prevents foreign body's like bacterium and dust from in bedding into the lungs causing infection.
What function does the immune system provide for the human body?
The function of the immune system is to protect your body from infections and illnesses. Your immune system works to identify pathogens and tumor cells that could cause disease and to eliminate them from your system. Your body's immune system has an incredibly difficult task in doing this because these pathogens and bad cells are sneaky: they can redesign themselves and adapt to changes your body makes to get rid of them. answer by Diamond Madison
How does resident normal flora protect the body against pathogens?
how does residental normal flora protect the body against pathogens
How does the pores in your skin protect you?
The pores on your skin help to prevent harmful pathogens from entering. Pathogens cause disease, infection and Cancer. By keeping these pathogens out, this is how pores protect you.
Where in the body do acids protect us from invading pathogens?
Immune system,
How does the body protect itself when such an accident happen?
the body protect itself when such an accident happen by it's recovering materials that can protect it from any accident .
One way white blood cells can protect the human body from pathogens?
they attack it
State one specific way white blood cells help to protect the human body from pathogens?
They don't defend pathogens. They defend *against*pathogens. They poison them, they burn them with ozone / hydrogen peroxide / sodium hypochlorite / chorine dioxide, and then they eat them whole if necessary.
How does your body protect itself from pathogens?
Firstly if your body gets infected with an unknown pathogen then it will build a memory so next the pathogen that infect the body will automatically eliminated and second how the body gets rid of the pathogen is by sending antibodies or whiteblood cells to kill the invaders
Why it is important that your body has several different defenses to protect you from pathogens?
Your body is really a possible large dinner table for pathogens that are found everywhere. You need as many defenses as you have to fend them off.
What group of pathogens do natural killer cells protect the body from?
Viral infections and cancerous cells
What is one way skin helps protect the body from infection?
Serves as a physical barrier to keep pathogens out.
What is the ability of the body to protect itself from its environment?
The ability of the body to protects itself from its environment is called homeostasis.
What can protect you from pathogens?
tears
