respiratory and integumentary system final

Question 1

clara cells

Answer 1

used in gas exchange, exist in terminal bronchioles. contain secretory granules

Question 2

secretory granules of clara cells?

Answer 2

surface active agent lipoprotein to prevent luminal adhesion and CC16 to protect against lung injury

Question 3

what increases in numbers along bronchioles?

Answer 3

clara cells

Question 4

conducting bronchi

Answer 4

where air is conditioned (warmed) and directed through nasal cavity, pharynx, larynx, trachea, and lungs

Question 5

respiratory bronchioles

Answer 5

first part allows for gas exchange. in both conduction and gas exchange, and contain clara cells

Question 6

blood air barrier

Answer 6

in alveolar septum, allows for gas exchange. consists of type 1 alveolar cells, fused basal laminae, and capillary endothelial cells

Question 7

type 1 alveolar cells fuse with what?

Answer 7

endothelium (endothelial cells of capillaries)

Question 8

larynx vocalis muscle

Answer 8

skeletal muscle attached to ligament. tension on ligament caused by muscle produces sounds

Question 9

surfactant

Answer 9

secreted by type II alveolar cells. surface active agent of lipoproteins and phospholipids, spreads over entire alveolar surface. decreases surface tension and prevents collapse. FORMS FILM

Question 10

trachea functions

Answer 10

conduction and conditioning of air

Question 11

function of trachealis muscle?

Answer 11

control luminal diameter of trachea to control air intake and allow for passage of swallowed bolus of food by esophagus

Question 12

stratum lucidum

Answer 12

in thick skin, thick layer. attaches to skin.

Question 13

meissner’s corpuscle function?

Answer 13

fine touch

Question 14

pilosebaceous gland?

Answer 14

unit made of hair bulb, hair follicle, and arrector pili muscle

Question 15

holocrine secretion?

Answer 15

mechanism of subcutaneous glands
