Concept explainers
Interpretation: Drawbacks of having large concentration of any substance in the body needs to be explained.
Concept Introduction: Steroids are generally drugs which are used to relieve swelling and inflammation. Steroids are manmade medicines to boost up the energy and hormones in our body.

Explanation of Solution
Cholesterol serves as the starting material in the body for the synthesis of other steroids. In vertebrae, cholesterol boosts up and forms another steroid.
Having very large concentration of a substance in the body can lead to overdose. This can impact our body in short term or long-term health issues. Coma, trembling muscles and convulsions, high body temperature, heart attack, blood pressure or stroke are the most dangerous symptoms of taking too large concentration of the toxic substances in the body.
There is a limit for the concentration of all the substances or elements in the human body. The more and less concentration than this, can lead to adverse effects on the body.
