Question 21

Identify

Answer 21

Lung (4x) with alveoli

Question 22

Identify

Answer 22

Lung, detail of pleura

Alveolar septum: thin wall for gas exchange from air to blood

Question 23

Identify

Answer 23

Lung, bronchus

• Cartilage is irregular rings or plates
• Smooth muscle in irregular bands - causes wavy (folded) mucosa

Question 24

Identify

Answer 24

Lung, regular bronchiole

• No cartilage
• Prominent smooth muscle - causes folds
• Less cilia than in bronchi

Question 25

Identify

Answer 25

Lung, terminal bronchiole - Non-ciliated columnar or cuboidal epithelium - No goblet cells - Less smooth muscle than in regular bronchiole - No folds

Question 26

Identify

Answer 26

Lung, respiratory bronchiole - Non-ciliated cuboidal or columnar epothelium - Clara cells (provide lubrication) - Alveolar outpocketings - where gas exchange occurs

Question 27

Identify

Answer 27

Lung, detail of bronchial epithelium transition - non-ciliated cuboidal epithlium at top - ciliated epithelium on bottom

Question 28

Identify

Answer 28

Lung, overview of parenchyma - Respiratory bronchiole: cuboidal epithelium, alveolar outpocketings - Alveolar ducts: providechannel for airflow from bronchiolar condiuts to alveoli. Septa and cusps project from ducts End of each duct is an alveolar sac

Question 29

Identify

Answer 29

Lung, alveolar organization - Ten or more alveoli opening into common area (the alveolar sac)
