The correct terms are "Bowman's capsule" and "proximal convoluted tubule (PCT)," followed by "loop of Henle," "distal convoluted tubule (DCT)," "collecting duct," and "peritubular capillary." Bowman's capsule is the initial part of the nephron that surrounds the glomerulus, and the PCT is the first segment of the nephron tubule. Each of these structures plays a crucial role in the filtration and reabsorption processes in the kidney.

The first capillary bed in the series is the glomerular capillary, where filtration occurs. The efferent arteriole on the distal end of the glomerular capillary. Objects it to the next capillary bed in the series: the peritubular capillary. This is where secretion and reabsorbtion take place. This type of system is an example of an arterial portal system.
Capillary beds
One important function of the capillaries in the peritubular capillary network is to facilitate the reabsorption of water, ions, and small molecules from the renal tubules back into the bloodstream. This process is crucial for maintaining fluid and electrolyte balance in the body, as it allows for the selective recovery of essential substances. Additionally, the peritubular capillaries play a role in the secretion of waste products and excess ions into the renal tubules for excretion. Overall, they are essential for efficient kidney function and homeostasis.
Peritubular fluid refers specifically to the fluid found in the renal tubules of the kidney, while interstitial fluid is found in the spaces surrounding cells throughout the body, including the kidney. While they both play a role in transporting substances and maintaining homeostasis, they are located in different anatomical compartments.
The glomerulus are a network of capillaries surrounding the renal tube. peritubular capillary beds
