Question 4

Pulmonary System Pediatric Note

Answer 4

• Tongues make up more space in pharynx
• Trachea is narrower, softer, and flexible
• Cricoid cartilage is less developed and less rigid
• Rib cage does not narrow on inferior end, generating negative pressure is more difficult
• Trouble breathing rely more on diaphragm (seesaw breathing pattern)
