Respiratory System

Question 1

Know Respiratory and conducting portion

Answer 1

PIC

Question 2

Nasal conchae (turbinate/turbinal)

Answer 2

3 long, narrow, curled shefs of bone that protrude into the breathing passage of the nose

Question 3

Chonchae are lined by…

Answer 3

respiratory epithelium with an underlying thick, vascular tissue layer

Question 4

What are swell bodies

Answer 4

Venus plexuses in the lamina propria of the chonchae. As blood flows into this plexus it helps to warm the inspired air

Pseudostratified ciliated columnar. Thick basement membrance and goblet cells
SEM shows cilliates surface, very short microvili/mucous

Question 8

Brush cells of Respiratory Epithelium are…

Answer 8

Chemosensory receptor cells with synaptic contact to afferent nerve endings

Question 9

Olfactory Mucosa Structure

Answer 9

PIC

Question 10

Olfactory Neurons are _____ present throughout the olfactory epithelium

Answer 10

bipolar neurons

Question 11

Are Olfactory cilia motile or non-motile?

Answer 11

Non-Motile that respons to odiferous substances by generating an action potential along axons

Question 12

What neurons make contact with basal lamina and are true pseudostratified?

Answer 12

Olfactory Neurons

Question 13

Larynx (voice box)

Answer 13

Located below the pharynx and above trachea

Question 14

True vocal cords are lined by…

Answer 15

Stratified squamous, non-keratinized Epithelium (has skeletal muscle)

Question 16

Conduction portion of Respiratory function

Answer 16

Consists of all the components that consition air and bring it into the lungs

Question 17

Respiratory portion of Respiratory function

Answer 17

Where gas exchange actually occurs, consisting of respiratory bronchioles, alveolar ductus, and alveoli in the lungs.

Question 18

Trachea is lined by

Answer 18

Respiratory Epithelium underlain by connective tissue of the lamina propria an sermucous glands

Question 19

Lungs

Answer 19

At the end of Trachea 2 bronchi branch and enter the lungs. Each lung is covered by PLEURA consisting of parietal (outer) and visceral (inner) layers

Question 20

Bronchiole differentiating differences

Bronchiole is lined by…

Answer 21

simple cuboidal to columnar ciliated spithelium, lacks cartilage and lacks seromucous glands

Question 22

What are Clara Cells

Answer 22

are domed shaped cells located in TERMINAL BRONCHIOLES which secrete antimicrobial peptides

Question 23

Respiratory Bronchiole lining…

Answer 23

similar to terminal bronchioles with the addition of some sacklike alveoli

Alveolar duct is completely lined by…

Answer 24

openings to aveoli

Question 26

Gases pass from ____ though ____

Answer 26

From the Alveolar Lumen through Type I pneumocytes, a fused basal lamina and endothelial cells enter a capillary

Question 27

Type II pneumocytes secrete…

Answer 27

surfactant that prevent alveolar collapse apon exhalation and allows aveolar inflation with less inspiratory force
