CH6 The Respiratory System Flashcards
Respiratory System Anatomy
what is Hypercabia or Hypercapnia
and Hypoxemia?
What part of the brain regulates breathing?
relates to the partial pressure of CO2 in blood.
hypoximia=low O2 concentration in blood
Medulla oblongata responds to these changes (increase or decrease respiration rate)
Path of deoxygenated blood from the heart to capillaries in alveoli and oxygenated blood back to the heart
deoxygenated blood travels to the alveoli from the right ventricle through the pulmonary ARTERY.
And oxygenated blood goes back to the heart into the left atrium via the pulmonary VEINS
Vasoconstriction relation as thermoregulator
Vasoconstriction occurs to preserve energy from being dissipated.
Occurs in cold enviroments
Bicarbonate buffer system and its equation
what is the mucociliary escalator
cilia propel mucus up the respiratory tract to get rid of unwanted particles
Macrophages
Can digest and engulf pathogens and signal immune system
what are Mast cells
have antibodies that when triggered can promote the release of inflammatory chemicals.
This is also can be caused by allergies
Lysozyme
Enzyme found in nasal cavity, saliva, and tears which degrades peptidoglycan, therefore, attacking gram positive bacteria
