What structural modification of certain tubule cells enhances their ability to reabsorb substances from the filtrate?
I'm assuming that the filtrate refered to is that of Bowman's capsule in the kidney. If so then ...
The cuboidal cells of the proximal convoluted tubule have long microvilli (brush border) on their apical (inside) surface that dramatically increase the surface area for reabsorption from the filtrate.
What else can I help you with?
The portion of the nephron receiving filtrate from the glomerular capsule?
The portion of the nephron receiving filtrate from the glomerular capsule is the proximal convoluted tubule. It is responsible for reabsorbing substances such as glucose, ions, and water from the filtrate into the blood. This process helps regulate the body's balance of electrolytes and fluid volume.
Materials are returned to the blood from the filtrate by which of the following processes?
Reabsorption is the process by which materials are returned to the blood from the filtrate in the kidneys. This process helps to maintain the body's balance of electrolytes, nutrients, and water by reabsorbing essential substances back into the bloodstream.
Which stage of urine production involves the removal of substances from the bloodstream?
Filtration in the glomerulus is the stage of urine production that involves the removal of substances from the bloodstream. This process separates waste products, excess ions, and other substances from the blood to form the initial filtrate that will eventually become urine.
Is plasma isotonic to glomerular filtrate?
Plasma is isotonic to glomerular filtrate, meaning that the concentration of solutes in the two fluids is similar. This isotonicity helps to maintain the balance of fluid and electrolytes in the body.
What is part of the nephron where substaces are filtered from glomerulus?
The Bowman's capsule is the part of the nephron that filters substances from the glomerulus. It surrounds the glomerulus and is responsible for collecting the filtrate that is produced.
Is a filtrate pure?
A filtrate doesn't contain insoluble substances but can contain soluble substances.
Where does secretion of substances into the filtrate occur?
Secretion of substances into the filtrate occurs primarily in the distal convoluted tubule and the collecting duct in the nephron of the kidney. This process helps in regulating the composition of the urine by removing additional substances from the blood and adding them to the filtrate for excretion.
This term means entry of substances into the body from the filtrate?
Reabsorption is the term used to describe the process of substances being taken back into the bloodstream from the filtrate in the kidneys.
What are two substances that are found in the filtrate but not in the urine?
Ions and nutrients
How is filtrate made?
Filtrate is made by passing a liquid through a filter, such as filter paper or a membrane, to separate solid components from the liquid. The solid substances are retained by the filter while the liquid, along with any dissolved substances, passes through as the filtrate.
What substances may be in the filtrate after the soap was filtered out?
Substances that may be in the filtrate after the soap was filtered out include water, dissolved salts, impurities or contaminants, and any other soluble components that were present in the original mixture.
What are two substances that are routinely found in filtrate but not in the urine product?
Ions and nutrients
What is themain functionof the proximalconvolutedtubules in urineformation?
reabsorption of most of the required substances from the filtrate
The filtrate removed from the blood by the kidneys might contain?
The kidneys remove toxic substances from the blood. The main substance that the kidneys filtrate from the blood is known as urea.
List two substances that are routinely found in filtrate but not in urine product?
ions and nutrients
What substances are removed from the filtrate and reabsorbed by the capillaries?
Substances like glucose, amino acids, and ions are reabsorbed by capillaries in the kidney. Waste products like urea and creatinine are typically removed from the filtrate and excreted in urine.
What substances are in both urine and glomerular filtrate?
Both urine and glomerular filtrate contain water, urea, electrolytes (such as sodium and potassium), and creatinine. Glomerular filtrate is the fluid that passes from the blood into the renal tubules, while urine is the final product after further processing and concentration by the kidneys. As glomerular filtrate is modified during its passage through the nephron, some substances are reabsorbed or secreted, leading to differences in composition between the two.
