What is the mechanical process of breathing called?
Exhalation
Ventilation
Inspiration
Respiration
What are the two phases involved in the mechanical process of breathing?
Inhalation and Ventilation
Inspiration and Expiration
Absorption and Secretion
Filtration and Reabsorption
What happens to the diaphragm during inhalation?
It moves upward.
It moves downward.
It remains stationary.
It expands outward.
What type of pressure exists within the thoracic space during inhalation?
Positive pressure
Neutral pressure
Negative pressure
Atmospheric pressure
Which muscles contract to increase the space in the thoracic cavity during inhalation?
Abdominal muscles
Intercostal muscles
Cardiac muscles
Smooth muscles
What happens to the diaphragm and intercostal muscles during expiration?
They contract
They relax
They expand
They stiffen
What occurs in the thoracic cavity during expiration?
The space increases, creating negative pressure
The space decreases, creating positive pressure
The space remains the same, maintaining pressure
The space decreases, creating negative pressure
What happens during inhalation in the respiratory system?
Air rushes out of the lungs.
Air rushes in through the airways to the alveoli.
Blood flows into the alveoli.
Carbon dioxide is absorbed into the bloodstream.
Where does the exchange of oxygen and carbon dioxide take place in the respiratory system?
In the trachea
In the bronchi
In the alveoli
In the diaphragm
What process allows the exchange of oxygen and carbon dioxide in the lungs?
Osmosis
Filtration
Diffusion
Active transport
Where does oxygen cross from the lungs to during gas exchange?
Veins
Capillaries
Arteries
Bronchioles
What waste product crosses from the capillaries into the lungs to be exhaled?
Nitrogen
Oxygen
Carbon dioxide
Hydrogen
Which part of the brain controls the process of respiration?
Cerebellum
Medulla oblongata
Hypothalamus
Thalamus
What triggers breathing when there is an increased amount in the blood?
Oxygen
Nitrogen
Carbon dioxide (CO2)
Hydrogen
Although the process of respiration is involuntary, how can a person control it?
By holding their breath
By breathing faster or slower
By thinking about breathing
By sleeping
When the diaphragm contracts, the pressure in our lungs (a) so in order to balance it the air must go (b) our lungs.
When we inhale the diaphragm (a) .
When we exhale the diaphragm (b) .
When the diaphragm relaxes, it moves (a) . The volume of the lungs (b) , thus (c) the pressure inside the lungs.
The volume of the lungs (a) causing the pressure in the lungs to (b) . This results in inspiration.
Match the following
Diaphragm Contracting
Diaphragm Relaxing
External Intercostal muscles
Internal Intercostal muscles
When air moves out of the lungs it is called (a) . When air moves into the lungs it is called (b) .
