What are the two additional muscles that help with inspiration during exercise
2. Pectoralis minor
What are the two additional muscles that aid with expiration during exercise
1. Internal intercostals
2. Rectus abdominus
Is inspiration active or passive during exercise
Is expiration active or passive during exercise
During inspiration the diaphragm and external intercostals...
During inspiration the sternocleidomastoid and pectoralis minor...
During inspiration the rib cage moves...
Up and out more
During inspiration the volume of the thoracic cavity...
During inspiration the pressure inside the lungs...
During exercise a larger volume of air moves...
Into the lungs
As a result of the changes to inspiration and expiration, what happens to breathing
Breathing frequency increases
During expiration, the external intercostals and diaphragm...
During expiration the rectus abdominus and internal intercostals...
During expiration the rib cage moves...
Down and in more
During expiration the volume of the thoracic cavity...
During expiration the pressure inside the lungs...
During expiration a greater visual of air moves...
Out the lungs
What is the chemical control receptor
What are the three neural control receptors
Define the respiratory control centre (RCC)
The RCC is situated in the brain and controls breathing rate and depth
Define what the inspiratory centre does (IC)
Part of the RCC that controls inspiration
Define what the expiratory centre is (EC)
The EC is part of the RCC that controls expiration
Define what the phrenic nerve is
The phrenic nerve stimulates the diaphragm to contract
Define what the intercostal nerve does
The intercostal nerve stimulates the external intercostals to contract
