EXPOSURE
Contact
You can be exposed to a hazardous material by:inhalation - breathing it in so it can damage the lungs or be passed to the blood for circulation through the bodyingestion - swallowing itskin contact - coming in direct contact with something that damages the skinskin absorption - coming in contact with something that does not damage the skin but moves through it and is then circulated through the body to sites where it can cause damageinjection - having it inserted into the muscle or blood through a needle or a cut or other damage to the skin
Conduction is the transferring of heat from one substance to another. Therefore, conduction usually occurs when one hot object comes into contact with another object that is not as hot.
Radiation injury, tissue damage or changes caused by exposure to ionizing radiation-namely, gamma rays, X-rays, and such high-energy particles as neutrons, electrons, and positrons.A chemical injury occurs where someone is exposed to a hazardous substance, either in the atmosphere or through direct contact with the skin.
A contact exposure would typically be in your system immediately after contact occurs. The duration it remains in your system can vary depending on the type of contact and the substance involved. It's important to wash the affected area thoroughly after contact to minimize any potential absorption into the body.

There different from each other because contact metamorphism is a local effect that occurs when molten rock meets solid rock, but on the other hand hydrothermal metamorphism occurs when very hot water reacts with rock, altering its mineralogy and chemistry.
Immunity occurs when the system recognizes a foreign substance and responds by producing : antibodies.
