Chapter 10 Flashcards
What does the respiratory system do
Brings in O2 and releases CO2
What is the function of the nose
to heat, humidify, and filter incoming air
What is the process of inspiration
diaphragm and intercoastal muscles contract, pressure in the chest decreases, and the external air pressure causes air to rush into the lungs
What is the process of Expiration
passive process involving the internal intercostal and abdominal muscles
adenoid/o
lymphatic tissue in the nasopharynx (upper portion of the throat)
tonsill/o
lymphatic tissue in the oropharynx (middle portion of the throat)
