BIOS 255 EXAM 3
1. Functions of the -Gas exchange
Respiratory Sys- -Communication
tem -Olfaction
-Acid-Base balance
-Blood pressure regulation
-Blood and lymph flow
-Platelet production
-Blood filtration
-Expulsion of abdominal contents
2. Describe high -ease with which the lungs and thoracic wall can be expanded
compliance as it High compliance= easy expansion
relates to healthy Low compliance= resisted expansion
functions.
3. Describe IRDS ( -leading cause of death in premature infants resulting from lack of surfactant
Infant respirato- production in alveoli
ry distress syn- -treated with artificial surfactant until they can make their own
drome) and de-
scribe the in-
terventions that
would be used
to help a new-
born premature
baby suffering
from IRDS.
4. Define antigens, antigens: large molecule capable of binding to an antibody or immune cells and
epitopes and an- triggering an immune response
tibodies. epitopes: certain regions of an antigen molecule that stimulate immune respons-
es
, BIOS 255 EXAM 3
antibodies: reacts with an antigen and aids in protecting the body from its harmful
effects
5. Identify the PO2 Respiratory bronchiole: 104mm Hg
measurements at Alveolus: 104mm Hg
the end of a Nasal cavity: atmospheric @ 159mm Hg
normal inhala- Trachea: 104mm Hg
tion ( breathing Bronchus: 104mm Hg
through the nose
) in each of the
following:
Respiratory bron-
chiole
Alveolus
Nasal cavity
Trachea
Bronchus
6. Describe the internal: exchange of gases between blood in systemic capillaries and tissue cells;
movement of O2 blood loses O2 and gains CO2
and CO2 in exter-
nal and internal external: exchange of gases between the alveoli of the lungs and the blood in
respirations and pulmonary capillaries across the respiratory membrane; pulmonary capillary blood
define gains O2 and loses CO2.
7. Pulmonary Venti- -breathing
lation -Inspiration (inhaling) & Expiration (exhaling) of air and involves the exchange of
air between the atmosphere and the alveoli of the lungs
8. Cellular Respira- Process that releases energy by breaking down glucose and other food molecules
tion in the presence of oxygen
