Pathogens can enter the body through various routes such as inhalation, ingestion, direct contact with broken skin, or through insect bites. Once inside, they can multiply and cause infection by evading the body's immune defenses and damaging tissues.
The largest organism that can enter the body and cause infection is typically a parasitic worm, such as tapeworms or roundworms. These worms can enter the body through contaminated food or water, and cause infections in various organs.
Pathogens are microorganisms that can cause disease in a healthy host, whereas opportunistic organisms are typically harmless, but can cause infection in hosts with weakened immune systems. Pathogens are generally more virulent and cause disease more readily than opportunistic organisms.
Some pathogens are naturally present in the environment, such as in soil or water sources. These pathogens can also be found in the human body as part of the normal microbiota. While some of these pathogens are harmless in healthy individuals, they can cause illness if they enter the body through a cut or wound.
Infection refers to the invasion and multiplication of pathogens within the body, often leading to tissue damage. Inflammation is one of the body's responses to infection, characterized by redness, swelling, heat, and pain at the site of infection.
The term for acquiring an infection through mucosal tissue is mucosal transmission. This occurs when pathogens enter the body through the mucous membranes lining the respiratory, gastrointestinal, or genitourinary tracts.
An infection occurrs.
The largest organism that can enter the body and cause infection is typically a parasitic worm, such as tapeworms or roundworms. These worms can enter the body through contaminated food or water, and cause infections in various organs.
The two mechanical barriers to infection are the skin, which acts as a physical barrier that prevents pathogens from entering the body, and mucous membranes, which line the respiratory, digestive, and urinary tracts and trap pathogens before they can enter the body.
yes
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.

Pathogens cause Infectious Diseases by pathogens getting into your body and caused harm.
they enter the bloodstream. when you get cut for example, the capillaries are broken, so there, the pathogens enter.

Antigens: BUT that is only true if the antigens cause a harmful reaction when they invade.
When pathogens enter the body, they begin to cause disease. Path=disease+ gen=to make (or generate).
