Solution Summary

This solution discusses the factors regulating filtrate formation in the kidneys. The three main concepts discussed in the posting include: autoregulation, osmotic pressure and hormonal control. The explanation is given in 394 words with two references.

Solution Preview

Filtrate formation is related to the glomerular filtration rate (GFR). GFR is determined by the glomerular blood hydrostatic pressure (GBHP; the 'push' of the blood through the filter), capsular hydrostatic pressure (CHP; the resistance to the blood coming through the filter), and blood colloid osmotic pressure (BCOP; the 'thickness' of the blood as its being pushes through the filter). All of these will combine to create the net filtration pressure (NFP = GBHP - CHP - BCOP).

1) Autoregulation: if the body wants to increase blood pressure throughout the body, the smooth muscle in the blood vessels leading to the kidney will contract which ...
