Alveolar ducts

Answer 9

Squamous cells with openings to alveolar sacs

Question 10

Alveoli

Answer 10

Alveolar sacs lined by type I and type II pneumocytes

Question 11

Respiratory portion

Answer 11

Gas exchange. Respiratory bronchioles, alveoli, alveolar ducts

Question 12

Conduction portion

Answer 12

Brings air into the lungs. Nasal cavities, pharynx, larynx, trachea, bronchi, bronchioles, terminal brochioles

Question 13

Nasal conchae (turbinal)

Answer 13

Three long, narrow, curled shelfs of bone that protrude into the breathing passage of the nose.

Question 14

Swell bodies

Answer 14

Venus plexus that helps to warm blood

Question 15

Respiratory epithelium

Answer 15

Pseudostratified ciliated columnar epithelium. Contains globlet cells and a thick basement membrane.

Question 16

Brush cells

Answer 16

chemosensory receptor cells that have synaptic contact to afferent nerve endings

Question 17

Fila olfactoria

Answer 17

bipolar neurons present in the upper layer of olfactory epithelium

Question 18

Vocalis muscle

Answer 18

Skeletal muscle in the true vocal cord that allows for voluntary control of the larynx.

Question 19

True vocal cord

Answer 19

stratified squamous non-keratinized epithelium. Contains the vocalis muscle

Question 20

False vocal cord

Answer 20

Respiratory epithelium. Inside you find serous/mucous glands

Question 21

Lungs

Answer 21

Contains a parietal (outer) and visceral (inner) layer

Question 22

Clara cells

Answer 22

Secrete surfactant and IgA. Highest concentration in terminal bronchioles

Question 23

Type I pneumocytes

Answer 23

Functional cell of alveoli, squamous epithelium

Question 24

Type II pneumocytes

Answer 24

They secrete surfactant that prevents alveolar collapse upon exhalation, cuboidal epithelium

Question 25

Olfactory epithelium

Answer 25

Pseudostraified columnar with sustentacular cells, olfactory cells, and basal cells. Bipolar neurons and Bowman’s glands are located below
