What are the routes for chemicals to enter the body?

Answer 1

the mouth If you mean into the blood stream, then a chemical may do so through a wound or across the thin wall of the alveoli in the lungs. You may also absorb chemicals as they diffuse from your small intestine into your capillaries

Answer 2

There are four major routes: * Inhalation (breathing) * Skin contact * Digestive system (ingestion or eating) * Injection Breathing of contaminated air is the most common way that workplace chemicals enter the body. Some chemicals, when contacted, can pass through the skin into the blood stream. Less commonly, workplace chemicals may be swallowed accidentally if food or cigarettes (or hands) are contaminated. For this reason workers should not drink, eat, or smoke in areas where they may be exposed to toxic chemicals. Injection is the fourth way chemicals may enter the body. While uncommon in most workplaces, it can occur when a sharp object (e.g., needle) punctures the skin and injects a chemical (or virus) directly into the bloodstream. The eyes may also be a route of entry. Usually, however, only very small quantities of chemicals in the workplace enter through the mouth or the eyes. Regardless of the way the chemical gets into the body, once it is in the body it is distributed to anywhere in the body by the blood stream. In this way, the chemicals can attack and harm organs which are far away from the original point of entry as well as where they entered the body.

Answer 3

1. Ingestion or Oral - you swallow it and it gets to you through your mouth, stomach, and intestines. 2. Inhalation - you breath it in through your mouth and nose and it is absorbed in the lungs. 3. Direct contact or skin contact - you touch it and it is absorbed through your skin. 4. Injection - you somehow get a cut or a needle poke that forces it directly into your bloodstream. Injection is the worst followed by inhalation and ingestion. Direct contact is typically the least harmful.

Answer 4

Depending on the toxin they can be inhaled, ingested, absorbed through the skin or enter through a wound

Answer 5

Ingestion, absorption and inhalation (through the skin, the mouth and nose)

Answer 6

by mouth

by injection through blood

by nose

Answer 7

You ingest (eat) it. Or, if you want to get real technical, you breathe it, since oxygen is a chemical.

Answer 8

Inhalation, absorption, ingestion
