When a pathogen enters the body, it first encounters the body's physical and chemical barriers, primarily the skin and mucous membranes. These barriers provide a first line of defense by preventing the pathogen from entering deeper tissues. If the pathogen breaches these surfaces, it then encounters immune cells and proteins in the innate immune system, which act quickly to identify and combat the invader.
reproduce. The more there is the more likely they are to survive x
During subsequent exposures to the same pathogen, the immune system is able to respond rapidly and activity reaches higher levels. The secondary immune responses can usually prevent disease, because the pathogen is detected, attacked and destroyed before symptoms appear.
It is called a pathogen! it carries the bacteria fugus disease or whatever else into the body!
The TB pathogen enters the body through inhalation of airborne droplets containing the bacteria. These droplets are released when an infected person coughs, sneezes, or speaks. Once inhaled, the bacteria can travel into the lungs and cause infection.
A very broad answer to a very broad question... A "pathogen" as defined by a dictionary would be, "any disease-producing agent, esp. a virus, bacterium, or other microorganism." First- a "pathogen" in drinking water will cause nothing unless someone or something drinks the water or if the "pathogen" enters the body/host by some other means... Second- even once the "pathogen" enters the body it may still cause nothing, as the quantity of the "pathogen" must be sufficient to cause the would be disease... Third- because a "pathogen" could be any one of millions of things, what disease would be caused by your hypothetical "pathogen in the drinking water" would depend entirely on what it is... You should seriously consider being more specific about your question. If you are interested in a specific pathogen and the associated disease, please try again.
Yes, contagious diseases are infections. Infections are occur when a pathogen (germ) enters the body and reproduces.
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
The second link in the chain of transmission in the body typically refers to the portal of entry for pathogens. After a pathogen is introduced through the first link (the infectious agent), it enters the body through specific routes such as respiratory passages, broken skin, or mucous membranes. This entry point allows the pathogen to establish infection and spread within the host. Understanding this link is crucial for implementing effective prevention and control measures.
During the second exposure to a pathogen, the immune system can mount a quicker and more targeted response due to immunological memory. This is because the immune system has already encountered the pathogen before and has memory cells ready to recognize and respond more efficiently to the pathogen. This results in a faster and more effective clearance of the pathogen from the body.
A microbe that attacks body cells is called a pathogen. Pathogens can include viruses, bacteria, fungi, and parasites that invade host cells and cause diseases.
