General Questions on respiration and the respiratory system
Diseases
100
What is the function of the Trachea?
This is the wind pipe through which air travels in and out of the body
100
Name the three functions of the nose
1. Prevents entry of dust particles
2. The mucus traps microorganisms, like bacteria and fungi (so they can't enter the body)
3. Moisturizes and warms the air that we breathe
100
What is the reactant gas of respiration?
Oxygen
100
What is the word equation for respiration?
oxygen + glucose --> carbon dioxide + water + energy
100
Name two diseases that can effect the respiratory system
The trachea divides into two tubes which enter each lungs. What are they called?
The bronchi (bronchus in singular)
200
Where does gas exchange take place?
Alveoli
200
What is the word equation for anaerobic respiration?
Glucose --> lactic acid + energy
200
Name the disease in which your airway walls become sore and swollen, narrowing so that your lungs get less air
Asthma
300
This is the structure that rises and falls when we swallow food. What is this structure called?
The Larynx
300
What do the lungs contain to make it easier for them to expand and contract?
Its filled with a watery fluid called the pleural fluid. This provides for the lubrication and free movement
300
What is the gas produced by respiration which plants can then use for photosynthesis?
Carbon dioxide
300
Around 2900 kJ of energy is released when one mole of glucose is broken down. The released energy is used to make a special energy molecule called _________.
Adenosine triphosphate (ATP)
300
What is Tuberculosis (TB)?
A bacterial infection that attacks the lungs and other parts of the body and can be deadly if not treated correctly
400
What is the main organ involved in respiration and what is its function?
The lungs.They provide a large surface area for the diffusion of oxygen from the air into the blood stream. (They contain) one cell thick walls of the air sacs called alveoli. Oxygen and CO2 diffuse through the walls of the alveoli.
400
The nasal chambers open into a wide cavity called the ________.
It is a common path for ________ and ________.
1. Pharynx
2. Food and air
400
Name at least one more organ that contributes to transporting oxygen rich blood around the body.
The heart
400
Name three things that organisms (that respire only) use respiration for.
1. Working your muscles
2. Growth and repair of cells
3. Building larger molecules from smaller ones (e.g proteins from amino acids)
4. Absorbing molecules in active transport
5. Keeping your body temperature constant
(Any three)
400
What is bronchitis?
An infection in your bronchial tubes
500
What structure forms very tiny air sacs called alveoli and what is the function of the alveoli?
The Bronchi. Alveoli provide for the diffusion of respiratory gases in and out of the blood stream
500
What are the walls of the trachea made of and how does this benefit the trachea?
It is made up of C- shaped cartilaginous rings
They provide strength to the trachea and keep it fully stretched/tense.
500
How does the structure of the alveoli (gas exchange takes place in) that allows diffusion to take place?
They are only one cell thick so it is easy for the gases to diffuse.
500
What is the difference between aerobic and anaerobic respiration?
Anaerobic means without air.
Organisms sometimes carry out respire without oxygen to produce the energy they need.
Aerobic means with air.
This type of respiration needs oxygen for it to occur
500
How does someone get chronic bronchitis?
It is commonly caused by cigarettes.
It can also be the result of :
Air pollution, dust, toxic gases, and other industrial fumes
