Many pathogens outside the body can be killed with heat or chemicals. Inside the body, pathogens can sometimes be killed with medicine.
how did the miwok and the hupa use their environment to survive
Most human pathogens belong to the mesophile group because they are able to survive and grow best at moderate and human temperatures.
The immune system needs to destroy the pathogens. Other wise the pathogens will multiply in the body of host. The pathogens will multiply by geometrical proportion. With in very short time the pathogens will occupy the whole body. You can no longer survive in that case.
The stomach protects the body from pathogens by producing highly acidic gastric juice, which kills most bacteria and viruses that enter the stomach. This acidic environment helps to break down food and prevent the growth of harmful microbes. Additionally, the stomach lining produces mucus that acts as a barrier to protect the stomach wall from damage and infection.
Intracellular pathogens. These types of pathogens rely on living host cells to survive and reproduce, making them more challenging to treat with certain types of medications or treatments.
no organisms adapt to the environment to help them survive
To survive to their environment

Natural selection favors the evolution of drug-resistant pathogens because when a population of pathogens is exposed to antibiotics, those that have genetic variations allowing them to survive and reproduce will pass on these resistance traits to future generations. Over time, this can lead to the emergence of drug-resistant strains as the surviving pathogens multiply.
Stomach acid is a chemical barrier against pathogens. The low pH of the acid creates an environment in which pathogens are unable to survive and will often kill them. Mucous is a physical barrier against pathogens. It acts to trap pathogens to prevent them from entering the body any farther.
