Misc.
100
These are tiny sacs in the lungs through which the exchange of oxygen and carbon dioxide takes place.
What is alveoli?
100
A unit of heat energy. The amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius.
What is a calorie?
100
One of the two thin-walled upper chambers of the heart.
What is the atrium?
100
The force exerted by blood against vessel walls.
What is blood pressure?
100
A transport system in which the fluid is confined within vessels.
What is closed circulatory system?
200
The mechanical process of moving air into and out of the lungs; also called ventilation.
What is breathing?
200
The process by which substances combine with oxygen.
What is oxidation?
200
A structure in the heart and some veins that prevents the blood from flowing backward.
What is a valve?
200
The rhythmic expansion and recoil of arteries; initiated by the contractions of the ventricles of the heart.
What is pulse?
200
When you inhale, your diaphragm
What is moves down?
300
Tiny hairlike extensions of cells that line the respiratory tract. They move in a wavelike fashion to help eliminate dust and germs from the body.
What is cilia?
300
A rapid form of oxidation that releases heat and, in many cases, light.
What is combustion?
300
One of the two thick-walled lower chambers of the heart; the pumping part of the heart.
What is the ventricle?
300
Carry oxygen, nutrients, and wastes; fight disease; and regulate temperature.
What are the main functions of blood?
300
Waste carbon dioxide passes into the alveoli from the bloodstream.
What is gas exchange in the lungs?
400
The amount of air the lungs can hold after taking as deep a breath as possible (the sum of vital capacity and residual volume).
What is total lung capacity?
400
The process by which glucose combines with oxygen to produce energy, carbon dioxide, and water.
What is cellular respiration?
400
Oxygen-poor (carbon dioxide-rich) blood from the body returns to this chamber of the heart.
What is the right atrium?
400
The five main parts of the circulatory system.
What are the heart, arteries, capillaries, blood and veins?
400
The pressure in the lungs decrease. The ribs move upward and outward. Air moves into the lungs.
What is inhalation?
500
The total amount of air that a person can exhale after taking as deep a breath as possible.
What is vital capacity?
500
An organic chemical in which energy is stored and from which energy is released to meet the body’s needs.
What is ATP (adenosine triphosphate)?
500
A group of specialized cells in the right atrium of the heart that establish the basic rhythm of the heartbeat.
What is the pacemaker?
500
The primary goal of cellular respiration is to release this from digested nutrients.
What is energy?
500
SARS, asthma and emphysema.
What are respiratory diseases?
