a ____________________ reaction occurs when chemicals enter the bloodstream through the skin, eyes, mouth, or lungs. your entire body can be damaged.

The blank is “systemic”. A systemic reaction occurs when chemicals enter the bloodstream through the skin, eyes, mouth, or lungs and are carried throughout the body, so your entire body can be damaged.

Quick Scoop

When a harmful chemical only irritates or burns the spot where it touched you (like a splash on the skin), that’s called a local reaction.

When it gets into your blood and travels all over your body, affecting organs such as the liver, kidneys, brain, or nervous system, that is a systemic reaction.

How the chemicals get in

Chemicals can enter your body through four main routes:

• Inhalation (breathing it in through lungs).
• Absorption through skin.
• Absorption through eyes.
• Ingestion (through the mouth, swallowing).

Once inside, many chemicals can cross into the bloodstream and be transported to different organs, causing widespread harm rather than just a surface burn or rash.

So the completed sentence is:
“A systemic reaction occurs when chemicals enter the bloodstream through the skin, eyes, mouth, or lungs. Your entire body can be damaged.”
