A&P chapter 15- respiratory system

Question 1

what are the function units of the lungs

Answer 1

air sacs called alveoli

Question 2

what is pulmonary edema

Answer 2

accumulation of fluid in the alcove

Question 3

what are the respiratory centers

Answer 3

medulla and pons

Question 4

What is intrapleural pressure and is it the same as atmospheric pressure

Answer 4

within the pleural space, is always slightly below atmospheric pressure (negative)

Question 5

where is intrapulmonic pressure

Answer 5

within the bronchial tree and alveoli

Question 6

what is tidal volume

Answer 6

amount of air in one normal inhalation and exhalation

Question 7

what is minute respiratory volume

Answer 7

amount of air inhaled and exhaled in 1 minute

Question 8

what is inspiratory volume

Answer 8

amount of air beyond tidal in a maximal inhalation

Question 9

what is expiratory reserve

Answer 9

amount of air beyond tidal in the most forceful exhalation

Question 10

what is vital capacity

Answer 10

sum of tidal, inspiratory and expiratory reserved

Question 11

what is alveolar ventilation

Answer 11

air that reaches the alveoli for gas exchange

Question 12

what is respiratory acidosis

Answer 12

a decrease in the rate or efficiency of respiration merits excess O2 to accumulate in the body fluids, resulting in the formation of excess H+ ions, which lower pH. occurs in severe pulmonary disease

Question 13

what is respiratory alkalosis

Answer 13

increase in the rate of respiration increases CO2 exhaled, decreases H+ ions and raises pH, during hyperventilation or when first at high altitude
