Anatomy Exam 3 Respiratory, Digestive
and Nutrition | Questions-Answers
Format| Correct Solutions
What are the functions of the respiratory system? - Ans--gas exchange,
regulation of blood pH, voice production, olfaction, protection
What are the different processes included in respiration? - Ans--Process of
exchanging gases between the atmosphere and body cells
What is the final process in which oxygen is used? - Ans--Gas exchange
What is the relationship between the respiratory and the cardiovascular
system in terms of gas exchange? - Ans--Respiration is the exchange of
gases between the atmosphere, blood, and cells. It takes place in three
basic steps:
Ventilation (breathing),
External (pulmonary) respiration
Internal (tissue) respiration
Cellular respiration
What are the organs of the respiratory system and their functions? - Ans--
Upper:
The nose
The nasal cavity
Sinuses
Pharynx
Lower:
Larynx
Trachea
Bronchial tree
Lungs
, How does the shape, tissues, and structure of the trachea relate to its
function? - Ans--The rings of the trachea help to keep the airway open so air
is able to pass through.
What are the structures found in the bronchial tree? - Ans--Trachea
Primary Bronchi
Secondary Bronchi
Tertiary Bronchi
Bronchioles
Terminal bronchioles
Alveolar ducts
Alveolar sacs
Alveoli
Where in the bronchial tree does gas exchange occur? - Ans--Alveoli
What is an alveolus? What types of cells does it have? - Ans--any of the
many tiny air sacs of the lungs which allow for rapid gaseous exchange.
What is a lung? - Ans--Soft, spongy, cone-shaped organs in the thoracic
cavity
Lungs are separated from each other by heart and mediastinum
Right lung has 3 lobes, left lung has 2 lobes
What is the pleura? - Ans--Is covering that protects the lungs (a double-
layered serous membrane to reduce friction of lung movement).
What is breathing? What are inspiration and expiration (and inhalation and
exhalation)? - Ans--is the movement of air from outside of the body into the
bronchial tree and the alveoli.
The actions responsible for these air movements are inspiration
(inhalation), and expiration (exhalation)
What drives the movement of air into and out of the lungs? - Ans--The
diaphragm
