Anatomy and Functions of Respiratory System Flashcards

1. gas exchange2. homeostasis3. smell4. speech5. pH balance6. remove excess heat and water 7. venous blood return8. protection

Protective mucus membrane - goblet cells (secrete mucus) and cilianasal hair - protects against large particles and insectsturbulent air flow - filters, warms and moistens air

They secrete mucus in the nose

Maxillary (2), sephnoid, ethmoid, and frontal sinuses

Pharynx is a tube shared by the respiratory and digestive systemnasopharynxoropharynxlaryngopharynx

Nasopharynx - adenoid tonsils (pharyngeal)internal nares to soft palate
part of pharynx

Contains palatine tonsilssoft palate to base of tongue
part of pharynx

Contains sublingual tonsilsbase of tongue (hyoid bone) to esophageal entrance
part of pharynx

The voice boxproduces sound

Folds in the direction necessary to send food to stomach or air to lungsprojects above the glottispart of larynx

Part of the larynxthe adams appleforms anterior and lateral surface of larynx

Part of the larynxforms posteroir support for larynx

Part of larynxproduce soundintrease tension - high pitchdecrease tension - lower pitch

The power of breathing - tree trunkattaches to cricoid catrilage (larynx) and ends at mediastium
branches into L/R pulmonary bronchicomposed of 10-11 trachial cartilages "C" shaped with tracheal muscles between cartilage (gives the trachea some flexion for when food passes thru esophagus)prevents collapse and protects airway

It branches off of the trachea into the L/R bronchi1. primary2. secondary3. teritary (divide until cartilages disapear)
