RESPIRATORY SYSTEM NOTES
Function:
Homeostasis:
Organs/ Structures and their functions:
Pleural membrane: Surrounds lungs holding them in the thoracic cavity. (sliding!)
Fun Facts: The lungs are one of the largest organs in the body.
Lungs are the only organs that float.
The surface area of your lungs is equal to that of a tennis court.
Inhalation: diaphragm contracts
The air pressure in the lungs
and the rib cage moves
causing air to enter the lungs.
Exhalation: diaphragm relaxes and the rib cage returns to resting position. The lungs
are
, causing the air to
the lungs.
Gas Exchange:
 Hemoglobin in the blood carries O2, which is unloaded from the blood cell into the tissues.
 In the tissue, O2 gets swapped with CO2.


The enzyme
aids in this exchange of gasses. The CO2 is
broken down into Carbonic Acid and later into bicarbonate ions that are capable of passing through cell
membranes for the exchange!
Gaseous CO2 is expelled from the lungs.
Diseases and Disorders of the Respiratory System:
1. Asthma: Bronchioles become
making it hard to breathe. Caused by sensitivity to particles
in the air and treated with inhalant medications.
2. Emphysema: Alveoli lose
and the ability to absorb O2. Caused primarily
by smoking, or other environmental toxins and is untreatable. Patients sometimes are restricted to pure
oxygen breathing apparatus in order to get enough O2.
3. Lung Cancer: Abnormal
in the lungs. Caused by smoking or
other environmental toxins and usually is untreatable. Patients will have a portion of their lung removed,
but only 10% survive once diagnosed.
