• 1. hyaline cartilage plates
• attached tofrontal, nasal and maxillary
• bones

2. external openings - external nares (nostrils)

• 1. cavity divided by nasal
• septum (hyaline cartilage) that exits
• through internal nares into pharynx

• 2. contains hair (filtration), numerous blood
• vessels (warms air), and mucus glands
• (traps debris and kills bacteria)

1. found in frontal, sphenoid, maxillary, ethmoid bones

• 2. respiratory functions – warm and moisten air,
• trap debris in mucus

3. drain into internal nose
