Respiration
Structure of the thorax
-
-
Bronchi -> Airways leading from the trachea to the lungs, dividing to form bronchioles
Cartilage -> A tissue that forms rigid supporting rings in the trachea to prevent collapse during pressure changes of venitlation
-
-
-
Pharynx -> The throat, both mouth and nasal cavities
Pleural fluid -> The fluid that lies between the two pleural membranes in the pleural cavity, acting as a lubricant while holding them together due to surface tension
-
Aerobic Respiration
-
Similar to combustion, except it is more slow and controlled, it is carried out in a series of small steps, and it involves the use of enzymes
-
Anaerobic Respiration
In Animals
-
Oxygen Debt
Lactic acid builds up and alters the pH of cells, denaturing proteins. Therefore, it is diffused into the blood stream and taken to the liver, where it can react with oxygen to break down

-
Ventilation
Inhalation/Inspiration
The volume of the thoracic cavity is increased, reducing pressure
Air moves from the atmosphere and into the lungs, down a pressure gradient
-
-
-
Exhalation/Expiration
The diaphragm becomes more dome shaped, and the ribs move downward
The volume of the thoracic cavity is decreased, increasing pressure
-
Air moves from the lungs and into the atmosphere, down a pressure gradient
