Decrease
Increase
The _______ zone which includes everything from the nose to the smallest bronchioles, moves air into and out of the lungs.
The ______ zone includes the respiratory bronchioles and alveoli and moves the respiratory gases, that is oxygen and carbon dioxide, in and out of the blood
Conducting zone
Respiratory zone
Bronchioles empty into
Alveolar ducts
Alveolar ducts dead end into
Alveolar Sacs
Where does gas exchange occur?
Alveolar Sacs
Hypocapnia is…
Drop in C02
What is the percentage of a particular gas divided by air pressure called?
Partial Pressure
Why is it hard to breathe at the top of a mountain?
Because the air pressure is lowe4
Hence, the partial pressure is lower
The same partial pressure already inside your lungs.
Making gas exchange difficult
This effect describes hemoglobin oxygen affinity is inversely related both to acidity and the concentration of carbon dioxide
Bohr’s effect
This effect is the decrease of hemoglobins oxygen binding capability with an increase in carbon dioxide or decrease in ph.
Bohrs effect
This effect is hemoglobins decreased carbon dioxide binding capabilities with an increase in oxygen
Haldane
Which process does the respiratory system use to facilitate gas exchange in and out of the lungs
Ventilation
External respiration is …..
Internal respiration is….
Between the lungs and the environment
Between the blood vessels and the cells
Inhaled oxygen travels down through the trachea, into the right and left bronchus, then into the Segmental Bronchi which branches further into the Lobar Bronchi.
False

Which are not part of the lower respitory system
Trachea
Carina
Pharynx
Bronchioles
Nasal Cavity
Pharynx & Nasal Cavities
During Inhalation, the diaphragm contracts upward to create positive pressure in the chest which allows the body to inhale oxygen
T or F
