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.
For instance, if the mean arterial pressure increases, renal autoregulation causes the afferent arteriole to constrict, preventing the pressure increase from being transmitted to the glomerular capillaries, and keeping the GFR from increasing.he figure illustrates the forces that determine the filtration rate. The pressure in the glomerular capillaries, PGC, favors filtration. Opposing filtration is the osmotic pressure due to the blood proteins (ÏGC) and the hydrostatic pressure in Bowman's space (PBS).
