Materials are returned to the blood from the filtrate by which of the following processes?
selective reabsorption
Where in the kidneys does the filtering takes place?
Within the nephron (the functional unit of the kidneys), filtration occurs in the glomerolus. The filtered fluid is called filtrate. Reabsorption of filtrate occurs in a few places within the nephron, however, the majority of reabsorption takes place in the proximal convoluted tube. It is important to mention that additional reabsorption occurs in the Loop of Henle, distal convoluted tube, and the collecting ducts as well. Again, however, MOST reabsorption of filtrate from the glomerolus takes place in the proximal convoluted tube of the nephron.
Summarize reabsorption in the proximal tubule?
Selective reabsorption of nutrients from filtrate back into the blood by active and passive transport.
Where does glucose take place?
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.
Most materials are reabsorbed from nephron tubules into surrounding blood vessels by the process known as?
Selective reabsorption
What is the difference between filtration and reabsorbtion?
Filtration Filtration is accomplished by the movement of fluids from the blood into the bowmans capsule. = Reabsorption = = Reabsorption involves the selective transfer of essential solutes and = water back into the blood.
The major process that takes place in the large intestine is?
In the colon, the major process that takes place is the reabsorption of water
What is the mechanism of urine formation?
The mechanism of urine formation takes place by three steps. they are glomerular filtration, tubular reabsorption and tubular secretion.
What is the process of reabsorption as it occurs in nephrons?
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 is the major function of a cell?
controlling the activeties of the organism such as: regulation of the internal system of an organisn selective reabsorption reproduction DNA production and is also nescessery for life.
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;
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.
