2 Breathing Mechanics Flashcards
What does Boyle’s law dictate?
Pressure exerted by gas is inversely proportional to its volume. ( P proportional to 1/V)
What is dalton’s law?
Total pressure of a gas mixture is the sum of the pressures of all individual gases (duh)
What is charles’ law?
Volume of a gas is proportional to temperature.
V proportional T
What is Henry’s law?
Amount of gas dissolved in a liquid depends on its solubility & pressure
What parts make up the upper respiratory system?
Mouth
Nasal Cavity
Pharynx
Larynx
What parts make up the lower respiratory tract?
Trachea
Bronhi
Lungs
What binds the lower respiratory system?
Ribs
Spine
Diaphragm
What is differnet about the external anatomy of the lungs?
The right lung has 3 lobes whereas the left only has 2
What are the lobes of the lung called?
Superior and inferior
The right lung also has a middle lobe
What encloses each lung?
Two pleural membranes seperated by a thin space of pleural fluid
What is the pericardial cavity?
The space around the heart
What is the inner pleural membrane called
The one around the lung (inner) is the visceral pleura
What is the outer pleural membrane called?
The one coating the inner rib surface (outer) is the Parietal pleura
What is inflammation of the pleura called?
Pleurisy
What do pleura do?
effectively stick the lungs to the ribs. This way the elastic recoil of the chess wall keeps the lung stretched open.
