Respiration Flashcards
How is carbon dioxide detected
Using limewater
Why is the Respiration word equation?
Glucose + oxygen > carbon dioxide + water + energy
What colour does Hydrogen Carbonate Indicator turn when carbon dioxide is present?
yellow
What colour does the Hydrogen Carbonate Indicator turn to when carbon dioxide is removed?
Purple
Why is it better to breathe through your nose rather than your mouth?
It stops dust and dirt getting into your body.

When we inhale….
The diaphragm moves down (contracts) and the rib cage moves up and out.

2
What are the 2 types of inhalers?

Respiration…
This is the process of glucose and oxygen reacting in cells to produce energy.
Organ systems…
A collection of organs that work together eg Oesophogus, stomach and small intestine found in digestive system.
Aerobic…
With oxygen
Respiration equation is…
Glucose + oxygen —> carbon dioxide + water + energy
Alveoli…
Air sacks at end of the bronchioles
Thorax…
Upper part of body
Abdomen…
Lower part of body
Trachea (wind pipe)…
Air flows through this
Cartilage…
Keeps the trachea (wind pipe) open
Pleural membrane…
Line the lung inside rib cage
Ventilation…
Getting air into and out of the lungs
Gas exchange…
Gases (carbon dioxide and oxygen) moving into and out of the blood
Inhaling…
Breathing in
Exhaling…
Breathing out
Intercostal muscles…
Muscles between the ribs
Volume…
The amount of space that the lungs take up
Pressure…
The force exherted inside the lungs
Asthma…
Causes difficulty in breathing as the small tube in the lungs swell restricting air flow. Usually caused by allergies.
