FLAC is free and open source! FLAC is short for Free Lossless Audio Compression. It is an open source codec and file format which provides a perfect quality audio file. FLAC files usually contain CD quality audio, but can also support almost any audio data with a wide range of sample frequencies, amount of channels and bits per sample. FLAC provides a smaller size of file than PCM WAV (about half the size), but much larger than lossy codecs like MP3.
The Afferent and Efferent arterioles will controls the renal plasma flow and the GFR. The more blood that is kept in the glomerulus (ie. afferent dilation and efferent constriciton) will increase the glomerular pressure and then increase the GFR while decreasing the renal plasma flow.
The rise in protein concentration is augmented if the glomerular plasma flow rate is low and is lessened at high levels of plasma flow. An accelerated rise in protein concentration will also accelerate the rise in oncotic pressure, a force that tends to oppose filtration and contribute to a lower GFR.
