- are constructed by combining systolic and diastolic pressure curves.
- The diastolic pressure curve is the relationship between diastolic pressure and diastolic volume in the ventricle.

Left ventricular volume (ml)
- The systolic pressure curve is the corresponding relationship between systolic pressure and systolic volume in the ventricle.
- A single left ventricular cycle of contraction, ejection, relaxation, and refilling can be visualized by combining the two curves into a pressure-volume loop.

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.
