CHAPTER 5: RESPIRATORY SYSTEM AND INTRO TO DIAGNOSTIC PROCEDURES AND TESTS

Question 1

The respiratory system consists of:

Answer 1

nose, pharynx, larynx, trachea, bronchi, lungs

Question 2

Function of respiratory system

Answer 2

exchange of O2 and CO2 between atmosphere and body cells. Called respiration and breathing

Question 3

External respiration

Answer 3

air containing O2 passes through the res. tract to the lungs where O2 passes from sacs in the lungs called alveoli to the blood in tiny blood vessels called capillaries. Simultaneously CO2 passes back from the capillaries to the alveoli and expelled through the respiratory tract

Question 4

Flow of Air

Answer 4

Inhalation: air enters nose or mouth, to pharynx, to larynx, to trachea, to bronchial tree, to alveoli
Exhalation: air containing CO2 leaves the alveoli, to the bronchial tree, to the trachea, to the larynx, to the pharynx, out the nose or mouth

Question 5

Internal respiration

Answer 5

The body cells take on O2 from the blood while giving back CO2 as a waste produced when food and O@ combine in cells, which is transported by the blood back to the lungs for exhalation.
