Detailed explanation-1: -Increased blood volume and increased blood pressure will increase GFR. Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease GFR. Hydrostatic pressure in the Bowman’s capsule will work to decrease GFR.
Detailed explanation-2: -All of the above choices affect glomerular filtration rate with the exception of answer choice D. Concentration of leukocytes in the blood.
Detailed explanation-3: -Viscosity of liquor and temperature This is one of the most significant variables both in filtration rate and rate of dewatering to a minimum moisture. Viscosity is closely related to temperature. As temperature is increased, viscosity is decreased resulting in a higher filter capacity and lower cake moisture.
Detailed explanation-4: -The net filtration pressure is determined by the balance of the Starling forces (the hydrostatic pressure and the oncotic pressure within the glomerular capillaries and Bowman’s capsule).
