How the proximal convuluted tubule are adapted for selective reabsorption?
microvilli increase the surface area for absorption / active transport; mitochondria produce ATP for active transport;
What does not impact how much sodium is reabsorbed?
Transport maximum of the renal proximal tubule
What substance is secreted by the proximal-tubule cells and prevents the pH of urine from becoming too acidic?
Ammonia
Which mechanisms reabsorb solutes from the glomerular filtrate?
Around 60-70% of the Glomerular Filtrate is reabsorbed in the proximal tube.
What is a hormone that prevents the loss of sodium ions?
Aldosterone. Aldosterone acts on the Na+/K+ ATPase pump in the Distal Proximal Tube/Collecting duct in the kidney. Importantly, when this pump action is up-regulated, Na+ re-absorption goes up along with WATER, which is recovered with the sodium ions.
Where does reabsorption primarily occur in the urinary system?
Proximal tubule
Where does selective reabsorption takes place?
The proximal convoluted tubule
Where does the reabsorption of glucose primarily occur in the kidneys?
in the proximal tubules
Reabsorption of glucose occurs primarily through the walls of the?
The reabsorption of glucose occurs primarily through the walls of the proximal convoluted tubule. It is found in the nephrons of the kidney.
Where does Most electrolyte reabsorption by the renal tublues occur?
Proximal tubule
What part of the renal tubule does reabsorption occur?
The Proximal Convoluted Tubules (PCT). The brush border cells of the PCT increase the cell's suface, which then helps with reabsorption.
Name the process by which molecules move from the proximal convoluted tubule into the blood?
Tubular reabsorption
Summarize reabsorption in the proximal tubule?
Selective reabsorption of nutrients from filtrate back into the blood by active and passive transport.
In the kidneys the largest volume of water reabsorption occurs in the?
proximal convoluted tubule
Which section of the nephron performs MOST of the glucose and water reabsorption?
proximal convoluted tubule
Where does glucose reabsorption occur in the nephron?
Glucose reabsorption takes place in the proximal renal tubule. This tubule is a portion of the nephron that contains fluid. The functions of the nephron include the reabsorption and secretion of various substances like ions, glucose, and amino acids.
What does a renal clearance test so?
An adaptation of the epithelial cells of the proximal civilities tubule for reabsorption is
