|
conducting zone is ? and what is its function? |
airways, air passages, allows air to move into the lungs |
|
|
the respiratory zone is ? and its function? |
alveoli, and capillaries its function is gas exchange |
|
|
pharynx? |
throat, serves as a passage way for food and air |
|
|
larynx is? |
voice box , it is the director of air should go |
|
|
trachea |
wind pipe, c shaped rings of hyaline cartilage, it allows big particles of food to pass by expanding |
|
|
bronchi is? |
where air is warm and cleansed, this is where air is passed through within the lungs |
|
|
what is each lung covered with ? |
visceral serousa |
|
|
the smaller branches of bronchi is called what? |
bronchioles |
|
|
when you inhale, the diaphragm |
contracts and moves inferiorly |
|
|
during inspiration , intrapulmonary pressure is? |
less than atmospheric pressure |
|
|
as volume expands |
pressure goes down |
|
|
as volume goes down |
pressure goes up |
|
|
pulmonary ventilation |
air must move into and out of the lungs so that gases in the air sacs are refreshed. this called breathing. |
|
|
external respiration |
gas exchange happens, this is where external respiration , gas exchanges are being made between the blood and body |
|
|
respiratory gas transport |
oxygen and co2 is transported to and from the lungs and tissue cells via the bloodstream |
|
|
what is the role of the surfactant in the lungs? |
reduces surface tension, so that the alveoli can expand |
|
|
intrapulmonary pressure |
pressure inside lung decreases as lung volume increases during inspiration |
|
|
intrapleural pressure |
pleural cavity pressure becomes more negative as chest wall expands during inspiration, chest wall recoils |
|
|
tidal volume |
amount of air inhaled/exhaled per breath |
|
|
inspiratory reserve volume |
extra air that can be inhaled |
|
|
vital capacity |
all the air that can be moved |
|
|
residual volume |
air left in lungs after forceful expiration |
|
|
Boyles law |
volume vs pressurw |
|
|
which muscles would be involved if you were to blow up a balloon! |
internal intercostals and abdominal muscles would contract |
|
|
inspiration involves |
an increase in intra pulmonary volume |
|
|
the process of normal expiration involves |
muscle relaxation and reduction in thoracic cavity volume |
|
|
the main regulatory chemical for controlling respiration is! |
carbon dioxide |
|
|
Tidal volume |
The amount of air inhaled/exhaled per breath
|
|
|
Vital capcity |
All the air that can be moved |
|
|
When you inhale |
Contracts and moves inferiorly |
|
|
The surfactant is what? |
Reduces surface tension Alveoli stay open Easier to breath |
|
|
Air flow is measured ? |
Diameter, length, viscosity |
|
|
What is the maximum volume of air that can be expelled from the lungs called! |
Vital capacity |
|
|
The partition that separates the nasal capacity from the oral cavity below is called the! |
Palate |
|
|
What muscular passageway served as a common passageway for food and air! |
Pharynx |
|
|
Name the brain center that sets the basic rhythm of respiration and expiration! |
Medulla |
|
|
The largest amount of carbon dioxide is carried in the blood in the form of! |
Bicarbonate ions |
