Respiratory intro + conducting Flashcards
Describe the anatomy of the respiratory system
conducting region and respiratory region
Describe the physiology of the respiratory system
exchange of O2 and CO2 gases
What does the respiratory system consist of
Nasal and oral cavities, pharynx (uvula and epiglottis), larynx (voice box), trachea (windpipe), lungs, bronchial tree, alveoli (site of gas exchange), pleurae (slippery, serous sacs and encase each lung)
What does the uvula do
flap which stops food from going up into the back of the nose
What does the epiglottis do
flap that prevents food from getting into the respiratory system; from entering the trachea and lungs
What does the larynx contain
vocal chords
What is the trachea
the windpipe
What does the trachea contain
tough rings of hyaline cartilage
Describe what the conducting region is and its function
system of tubes that provides a passage for air to enter and leave the lungs
What does the conducting region compromise of
Nares (nostrils), Nasal/oral cavities, Pharynx, Larynx, Trachea, Primary bronchi (left and right to each lung), Secondary and tertiary bronchi, Bronchioles, Terminal bronchioles
The conducting region also does what alongside providing a pathway for gases to enter and leave the body
Expel inhaled matter such as dust/ bacteria
Particulate matter is trapped by what
Mucus secreted by goblet cells
What sweeps the mucus and bacteria towards the oseophagus
Cilia on epithelial cells
Cilia lines what in the lungs
Primary bronchus
The upper regions of the resp tract such as the pharynx has what type of epithelial that resist wear and tear
Squamous flattened
