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.
Contraction or relaxation of the artery can affect the pressure of capillaries in the glomerulus, and consequently the filtration of blood. Sympathetic nervous system action as well as hormones can also impact glomerular filtration rate by modulating afferent arteriole diameter.lood enters the capillaries of the glomerulus by a single arteriole called an afferent arteriole and leaves by an efferent arteriole. The capillaries are lined by a layer of cells (an endothelium) that has a unique structure, allowing blood components to be filtered, and resulting ultimately in the formation of urine.
