Question 1

Toxicology

Answer 1

Studies the effects of chemicals, such as drugs, alcohol, poisons, metals and gases on the human body.

Question 2

Toxins

Answer 2

A naturally occurring poison produced by living organisms such as bacteria, fungi; plants, insects and algae.

Question 3

Toxicant

Answer 3

Manufactures and extracted chemicals (pesticides, cleaning agents, industrial emissions or by-products, mining by-products, etc.) that are in our environment and produce adverse biological effects of any nature.

Question 4

What makes a poison?

Answer 4

The dose

Question 5

Safe dosage

Answer 5

Depends on height, weight, and other substances present in the body. Some are only harmful with large doses.

Question 6

Nutrient

Answer 6

A substance that the body needs to maintain life and health. (proteins, lipids, vitamins, minerals)

Question 7

Molecules

Answer 7

A group of atoms held together by chemical bonds.

Question 8

Digestive System

Answer 8

Breaks food into nutrients and molecules. Removes waste that is not needed from food.

Question 9

Extracted molecules are used for:

Answer 9

Building body parts, such as creating new cells for wound repair. Driving chemical reactions (aerobic respiration), and supplying energy to the body.

Question 10

Physical Digestion

Answer 10

The mechanical act of breaking down food into smaller parts.

Question 11

Chemical Digestion

Answer 11

The body’s use of acids and enzymes to break down foods into smaller molecules. Example, enzymes in saliva and lipaes in the small intestine.

Question 12

Digestive System

Answer 12

1. Oral Cavity, Teeth, Tongue, Salivary Glands (where food enters)
2. Esophagus (transports food to stomach)
3. Stomach (contracts to break down food)
4. Small Intestine (further absorption, further breakdown)
5. Large Intestine (reabsorbs water, forms feces)

Question 13

Metabolism

Answer 13

The chemical process of breaking down molecules for energy and of using simple building blocks to build up more complex molecules needed for growth and repair.

Question 14

Metabolites

Answer 14

Small molecules produced as byproducts during metabolism (found in blood, sweat, urine, skin, hair, nails, other cells/tissues).

Question 15

Forensic Chemistry

Answer 15

A field of chemistry that tests non-biological samples, such as powders, pills, and other substances, to identify them, and quantify them.

Question 16

Presumptive Tests

Answer 16

Marquis - purple color change when positive

Question 17

Confirmatory Tests

Answer 17

Gas Chromatography

Question 18

What they test for:

Answer 18

Acetylsalicylic Acid
Acetaminophen
Oxycodene
Ecstasy

Question 19

Forensic Toxicologist

Answer 19

Analyzes the samples that the medical examiner has given to look for substances that may have contributed to death. Forensic toxicologists play an important role in determining how a person died.
