Final answer:
Pesticides can enter the body through the mouth, skin, nose, and eyes, leading to potential internal organ damage after entering the bloodstream.
Step-by-step explanation:
Pesticides can enter the body through various routes of exposure: the mouth, skin, nose, and eye. When pesticides enter through the mouth, they enter the digestive tract.
Contact with the skin or eyes can lead to absorption into the bloodstream, potentially reaching vital organs like the lungs, liver, kidneys, or nervous system. Inhalation through the nose is another way for chemicals to access the bloodstream and damage internal organs.
Special attention is needed in occupations such as agriculture, manufacturing, and emergency response where exposure risks are enhanced. Protection and prevention are critical to avoid the adverse health effects that can result from pesticide exposure.
