Components of the respiratory system include the:
nose, pharynx, larynx, trachea, bronchi, lungs(with their alveoli), diaphragm & muscles surrounding the ribs.
Name the 8 major components of the respiratory system:
Respiration is controlled by the
respiratory control center
Where is the respiratory control center located
In the medulla of the brain
The respiratory system
supplies oxygen to the body & eliminates carbon dioxide.
refers to the exchange of gases between the atmosphere & the blood through the alveoli.
Internal respiration refer to the
exchange of gases between the blood & the body cells.
Diagram of: Respiration, External Respiration & Internal Respiration.
The passageways between the __a___ __a__ & the
a. nasal cavities
The upper passageways also serve to
warm, filter & moisten incoming air.
The upper respiratory tubules are lined with _____ that help to trap debris & keep foreign substances from entering the lungs.
Exhalation is a passive process during which
the lungs recoil as the respiratory muscles relax & the throax (chest area) decreases in size.
Most of the oxygen in blood is
bound to hemoglobin in red blood cells.
Some carbon dioxide is
carried in solution or bound to blood proteins, BUT most is converted to bicarbonate ion by carbonic anhydrase w/in red blood cells.
What happens to SOME carbon dioxide in the body?
They are carried in solution or bound to blood proteins.
What happens to MOST carbon dioxide in the body?
It is converted to bicarbonate ion by carbonic anhydrase within RBC's (red blood cells).
Because most carbon dioxide is converted to bicarbonate ion this reaction
releases hydrogen ions, carbon dioxide is a regulator of blood pH.
Is carbon dioxide a blood pH regulator?
