An infection occurrs.
When pathogens enter the body, they begin to cause disease. Path=disease+ gen=to make (or generate).
Many pathogens outside the body can be killed with heat or chemicals. Inside the body, pathogens can sometimes be killed with medicine.

for diseases to enter the body they must penetrate the skin
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.
Pathogens (bacteria and viruses that cause disease) can enter the body through various passages. Skin provides good protection against entry from pathogens so your vulnerable areas are your eyes, nose, mouth, ears and open wounds. Your (unwashed) hands can deliver pathogens to these areas. Airborne pathogens will enter through the mouth or nose as you breath them in. Pathogens in food will enter through your mouth into your digestive system. Pathogens can also enter through "vectors" directly into the blood stream - through mosquitos, fleas, ticks or contaminated needles, for example. It is important to remember that the body has many natural defenses to prevent pathogens entering the body, such as blood clotting at wounds, and enzymes in the eyes, nose and mouth that break down harmful bacteria.

There are many types of immunoglobulin within the body. They are part of the immune response which the body activates when a pathogen/bacteria/virus enters the body. The body responds by initiating an innate response in which pathogens are phagocytosed (literally eating) by defense cells. The immunoglobulins help recognise these pathogens and tell the body that they are a foreign material so they can be destroyed.
A fever often occurs as a response to infection because it is part of the body's immune response to pathogens. When tissues are damaged by pathogens, the immune system releases pyrogens, which are substances that signal the hypothalamus to raise the body's temperature. This elevated temperature can enhance the effectiveness of immune cells, inhibit pathogen growth, and create an environment less favorable for the survival of many pathogens. Consequently, a fever can help the body fight off infections more effectively.
Two physical defenses that protect the body against pathogens in a swimming pool are the skin and mucous membranes. The skin acts as a barrier, preventing pathogens from entering the body, while mucous membranes, such as those found in the respiratory and gastrointestinal tracts, trap and help expel harmful microorganisms. Additionally, the presence of chlorine in pool water helps to kill many pathogens, further reducing the risk of infection.
There are many channels are in females body. Your body is always busy moving and making things also your body has to make sure it has the right material cells and how many enter and exit the body.
