The proximal convoluted tubule (PCT) is a small tubular structure within the nephron of the kidney. The PCT connects Bowman's capsule with the proximal straight tubule, and it is essential for the reabsorption of water and solutes from filtrate within the nephron.
Juxtaglomerular Apparatus. This is a region where, in each nephron, the distal convoluted tubule touches the afferent arteriole. The juxtaglomerular cells are part of the afferent arteriole and the macula densa is part of the distal tubule.Renin is secreted from the JG cells and is important in regulating systemic blood pressure.he result is increased rate of flow and increased osmotic pressure (OP) in the distal convoluted tubule of this nephron. The macula densa (MD) on the tubule side of the juxtaglomerular apparatus is sensitive to the osmotic pressure (OP) and/or the rate of flow of the filtrate.
