Exam 3- Respiratory And Digestive| With
100% Correct Answers | 2026 Update
What are the functions that can be carried out by the respiratory system? -
Ans---Production of RBC
-Stimulation of protein and lipid metabolism
-Regulation of blood glucose levels
The rate and depth of breathing influences the blood levels of oxygen (O2),
carbon dioxide (CO2), hydrogen ions (H+), and also influences the venous
return of blood and lymph due to changes in compression within the
thoracic cavity that occur during breathing. T or F - Ans--True
What are the respiratory structures in the order that the air would pass as it
went from the outside to the inside of the body?
ex: nasal cavity - Ans--Outside
Nasal cavity
Nasopharynx
Oropharynx
Laryngopharynx
Larynx
Trachea
Inside

2 bronchus
3 bronchus

Inside
The right lung has ___ lobes, and the left lung has ___ lobes. - Ans--Three;
two
The Pleural cavity - Ans--is a potential space that contains a lubricating fluid
that allows the visceral and parietal pleura to slide by each other easily.
Function of lymph nodes in the lungs - Ans---They collect carbon, dust
particles, and pollutants.
- They are located within the connective tissue of the lung
-They are located around the bronchi and pleura
Respiratory bronchioles typically are lined by a simple cuboidal epithelium,
and both the alveolar ducts and alveoli are lined by a simple squamous
epithelium.
T or F? - Ans--True
The thin barrier that oxygen and carbon dioxide diffuse across during gas
exchange between the alveoli and the blood in the pulmonary capillaries is
the _______ membrane. - Ans--Respiratory
The lungs cling to the internal surface of the chest wall and are composed of
vast amounts of elastic connective tissue that causes the lungs to exhibit a
noticeable outward pull.
T or F? - Ans--False
During inhalation, the thoracic cavity ___________; during exhalation, the
thoracic cavity ___________. - Ans--becomes larger; returns to its original
size
External respiration involves the exchange of gases between the
atmosphere and the blood.
T or F? - Ans--True
