respiratory system Flashcards
(8 cards)
Visceral pleura
lining on the lung side
Parietal pleura
lining on the rib side
Pleural space and what is its function
between linings, Lubrication decreases friction and maintains surface tension
hwo many lobes are on the right side of the lung
3 lobes
how many lobes are in the left side of the lung
2 due to presence of the heart
what happens during inhalation
-diaphragm down
-intercostal muscles out
-increased volume decreased pressure
what happens during exhalation
-relaxation of ribs in and diaphragm up
-decreased volume and increased pressure
what does the medulla oblongata control
-determines depth and rate of breathing
-changes breathing rate
cause chemoreceptors in aortic/carotid
bodies to send nerve impulse to
stimulate an increase in
breathing rate
