Answers

Paul
1.Inhalation
Breathing and smoking causes us to inhale substances which enter the lungs.
Substance inhaled into the lungs are readily absorbed into the blood stream.

2.Ingestion
Swallowing a substance causes penetration into the blood stream via the stomach and small intestine.
It also occurs through food chain eg eating toxic animal products.

3.Absorption
Entering the body through the skin causes substances to enter the blood stream at a slower rate than by inhalation or absorption.
However, the resulting entry and distribution within the body is the same.

4.Injection
Injection occurs when substances are forced through this skin. This can occur as a result of such means as compressed air, or by having the skin abraded by a penetrating object.
