100
A unit within a cell that carries out a particular function; like "organs" for cells
What is an organelle?
100

Includes reproduction, transportation, nutrition, respiration, excretion, growth, response to stimuli

What are the essential life functions?

100
This results when essential nutrients are missing from a diet
What is malnutrition?
100
The property of a system in which internal conditions remain stable and balanced
What is homeostasis?
100
A particular abnormal condition; a disorder of structure of function, that affects all of part of an organism
What is disease?
200
Scientific study and explanation of cells, what they are and how they function
What is cell theory?
200
The process by which plants make their own food from light energy, carbon dioxide, and water
What is photosynthesis?
200
the primary energy source for the human body, in the form of sugars and starches
What are carbohydrates?
200
A change in external environment triggers these, causing your body to maintain internal balance
What are response mechanisms?
200
Known as the "silent killer" because there are often no symptoms; an illness that damages blood vessels
What is high blood pressure?
300
Organelle that controls all of the activities of the cell and contains the DNA
What is the nucleus?
300
Organ system that pumps fluid and transports nutrients and waste products throughout the body
What is the circulatory system?
300
The amount and type of food you eat every day (this word is often used incorrectly)
What is diet?
300
The pancreas responds to increased blood sugar levels by releasing this hormone
What is insulin?
300
Holes in the lining of the esophagus and stomach; most of these seem to be genetic, rather than caused by stress or behaviours (as is commonly thought)
What are ulcers?
400
Organelle that exists in plant cells only, and contains the pigment chlorophyll
What is the chloroplast?
400
The technical name for a blood pressure cuff (p. 192)
What is sphygmomanometer?
400

Starts with the mouth, breaks down food physically and chemically, responsible for absorption of nutrients

What is the digestive system?

400
These two organ systems work together to maintain blood sugar levels, hydration, enzyme levels, and waste product levels
What are digestive and circulatory systems?
400
Serious chronic disease with no cure; there are two main types: 1) pancreas no longer produces enough insulin, 2) insulin does not work
What is diabetes?
500
The "powerhouse" of the cell, releases energy from digested food
What is mitochondrion?
500
Uses glucose and oxygen to release energy within a cell; occurs in the mitochondria
What is cellular respiration?
500
a biological catalyst that assists in chemical digestion (breaking down food into smaller particles)
What is an enzyme?
500
The ___________ of substances in the blood are always changing; organ systems work together to maintain healthy levels and transport substances around the body
What are concentrations?
500
This occurs when the heart stops
What is cardiac arrest?
