WebJan 17, 2024 · Key Terms. Bowman’s capsule: A cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney.; proximal tubule: The first and primary sort of water and ion reabsorption in the kidney, where all glucose in the blood is reabsorbed.; glomerulus: A small, intertwined group of capillaries within the nephrons of … WebThe reabsorption of water in the earlier parts of the nephron (regardless of a person's state of hydration), independent of ADH is termed as 'obligatory reabsorption of water', whereas the water reabsorption in the distal part of the nephron (in accordance with the body's state of hydration), under the influence of ADH, is termed as 'facultative reabsorption of water'.

WebSite of filtrate formation. proximal convoluted tubule: Primary site of tubular reabsorption. distal convoluted tubule: Secondarily important site of tubular reabsorption. collecting duct: Structure that conveys the process filtrate (urine) to the renal pelvis. peritbular capillaries: Blood supply that directly receives substances from the ... WebKidney Reabsorption. Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: Specialized proteins called transporters are located on the membranes of the various cells of the nephron. These transporters grab the small molecules from the filtrate as it flows by them.
WebThis is called obligatory water reabsorption, because water is “obliged” to follow the Na + (Figure 25.18). Figure 25.18 Substances Reabsorbed and Secreted by the PCT . More substances move across the membranes of the PCT than any other portion of the nephron. Webureters.
