1 maj 2024 · Renal plasma flow – the perfusion of the glomerulus is an important determinant of GFR, as the blood flow provides the required hydrostatic pressure for ultrafiltration. The RPF is determined by the pressure gradient through the renal vasculature divided by the total renal vascular resistance.
• The kidney’s regulation of volume and composition of extracellular fluid by the processes of filtration, reabsorption and secretion • The gross structure of the kidney, which is a cortex surrounding a medulla containing an inner cavity, the pelvis • The functional unit of the kidney – the microscopic nephron (1 million in each kidney)
Renal structure and function. Kidney structure... Functions of the kidney. Production of urine ... The glomerulus. Introduction. The glomerulus is at the start of the nephron and provides the first step in filtering the blood to form urine.
Download chapter PDF. Learning Objectives. To understand the processes of glomerular filtration as the first process involved in urine formation. To describe the physical determinants of the glomerular filtration rate. To describe the functions of renal blood flow and the mechanisms of autoregulation.
Define renal blood flow, renal plasma flow, glomerular filtration rate, and filtration fraction, and give normal values. State the formula relating flow, pressure, and resistance in any vascular bed. Identify the successive vessels through which blood flows after leaving the renal artery.
