The PCT is located in the renal cortex, the outer part of the kidney, and is the first segment of the renal tubule, where it receives the filtrate from the renal corpuscle. Selain itu, pengaturan kalsium oleh hormon terjadi di tubulus berbelit-belit bagian distal. Proximal convoluted tubules are lined by epithelial cells that constitutively express aquaporin channels and are therefore generally the MOST permeable to water. The proximal convoluted tubule is located within the renal cortex and as its name suggests, it is the most coiled section of the renal tubule. First, as shown in Fig. The proximal tubules make up a significant portion of the kidneys; proximal tubule epithelial cells are the most populous cell type in the kidney, and carry out diverse regulatory and endocrine functions where numerous transporters are located. Tubulus proksimal adalah bagian dari nefron, suatu sistem yang menyaring darah yang melewati henle asenden. Terukur sekitar 15 mm dan berdiameter 55 nanometer.
