Pulmonary System

Question 1

Systems in Speech Production (and what they provide)

Answer 1

Respiratory, Laryngeal, Supralaryngeal Respiration, Phonation, Resonation Source of energy, Vibration, Resonator

Question 2

Vertebral Column

Answer 2

Cervical (C1-7) Thoracic (T1-12) Lumbar (T1-5) Sacral (5 fused) Coccygeal (4 fused)

Question 3

Skeletal Thorax (functions)

Answer 3

AKA: Rib Cage

• Thoracic Vertebrae
• Ribs
• Sternum
  
  • Houses visceral organs
  • Protects and supports respiratory function
  • Provides attachments for numerous muscles

Question 4

Bones in the Pulmonary System

Answer 4

Sternum

• Manubrium
• Body
• Xiphoid Process

True Ribs (1-7)

False Ribs (8-10)

Floating Ribs (11-12)

Question 5

Cartilage of the Pulmonary System

Answer 5

Costal Cartilage (true ribs)

Costal Arch (false ribs)

Question 6

Ribs are attached to…

Answer 6

Thoracic Vertebrae

Question 7

Parts of the respiratory system

Answer 7

UPPER

• Nasal Cavity
• Oral Cavity
• Pharyngeal Cavity

TRACHEA

LOWER

• Layrnx
• Trachea
• Bronchi
• Alveoli

LUNGS

Question 8

Which lung are foreign objects more likely to fall into?

Answer 8

The right branch is shorter, larger, and more in line with the trachea.

Question 9

What is surfactant?

Answer 9

• Excretion released by alveolar cells
• Lowers surface tension of the alveoli
• Prevents alveolar collapse

Question 10

What are different types of pleura, pleural linkage, and intrapleural pressure?

Answer 10

Responsible for connecting lungs to thorax, and allowing movement without puncturing.

• Visceral Pleura
  
  • Covers the lungs
• Parietal Pleura
  
  • Covering inside of the thorax

Pleural Linkage: thin layer of fluid creates BONDS, which leads to NEGATIVE intrapleural pressure

Question 11

What are tiny finger-like projections that help move particles trapped in mucus to the pharynx to be coughed out or swallowed?

Answer 11

Cilia
