Compliance of the lung Figure

- Transmural pressure is alveolar pressure minus intrapleural pressure. -When the pressure outside of the lungs (i.e., intrapleural pressure) is negative, the lungs expand and lung volume increases.

- When the pressure outside of the lungs is positive, the lungs collapse and lung volume decreases.

- Inflation of the lung (inspiration) follows a different curve than deflation of the lung (expiration); this difference is called hysteresis.

- In the middle range of pressures, compliance is greatest and the lungs are most distensible.

- At high expanding pressures, compliance is lowest, the lungs are least distensible, and the curve flattens.

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
