The proximal convoluted tubules reabsorb what percentage of filtered water?
Wiki User
∙ 13y ago
The largest amount of solute and water reabsorption from filtered fluid occurs in the proximal convoluted tubules, which reabsorb 65% of the filtered water, Na+, and K+; 100% of most filtered organic solutes such as glucose and amino acids; 50% of the filtered Cl-; 80-90% of the filtered HCO3-; 50% of the filtered urea; and a variable amount of the filtered Ca2+, Mg2+, and HPO42- (phosphate). In addition, proximal convoluted tubules secrete a variable amount of H+ ions, ammonium ions (NH4+), and urea.
So your answer is 65%

What hormone from the adrenal cortex will cause the distal convoluted tubules to reabsorb more sodium ions?
adh
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 are cells that reabsorb bone?
osteoclasts
What does ADH make the kidneys do?
Increases how much water the collecting ducts in the kidney reabsorb.
Why sugar does not appear normally in urine?
The nephrons (filtering units in the kidney) actively reabsorb glucose from the urine. Up until a blood sugar of about 200, there should normally be no glucose found in the urine. Glucose in the urine (also called glycosuria), can be seen in diabetes and other conditions that cause an increased blood glucose. There are also some conditions that prevent the nephron from reabsorbing glucose filtered in the kidney.

Which mechanisms reabsorb solutes from the glomerular filtrate?
Around 60-70% of the Glomerular Filtrate is reabsorbed in the proximal tube.

What is the medical term meaning Microscopic tube where urine is formed?
It is the nephron, the basic structural and functional unit of the kidneys. Its main job is to regulate waste and filter the blood and excrete toxins via urine.the microscopic tube where urine is formed is called the nephron. They are located in the kidneys.renal tubulesIt's a complex answer. Urine is formed in the kidneys in cellular structures known as "renal parenchyma". Urine is the filtrate of blood traversing the microscopic pathways from the glomerulus to the proximal convoluted tubule, the loop of henle, and the distal convuluted tubule which is where the final condensed urine is collected.I'm afraid the answer is not as straightforward as your question. At the beginning, urine filtrate is filtered out of the blood through a knot of capillaries called the glomerulus into an encapsulated space called the glomerular capsule. From there, the filtrate passes through a couple of tubes. The first is the proximal convoluted tubule where many of the things that were filtered out are reabsorbed back into the blood. Then the urine filtrate passes through the loop of Henle which primarily acts to reabsorb salt. This regulates our blood sodium levels and helps determine the concentration of our urine. Finally the urine filtrate passes through the distal convoluted tubule where even more refinement of the content of urine is performed. Finally, the urine will drain into a collecting duct which will drain into the calyces and eventually the ureters to the bladder.the urethra transports urine from the bladder to the end of the penis.the nephrons
Rising blood levels of aldosterone cause the kidney tubules to?
To reabsorb more sodium and some tme that can lead to an edema (oedema)
Can you give me a sentence that uses the word reabsorb?
The beans are then returned to the water to reabsorb the flavors.
What hormones retains sodium in the body?
aldosterone retains salt at the distal convoluted tubule and the water follows
What us the primary function of the distal convoluted tubule?
The Distal Convoluted Tubule or DCT, acts as a site for selective secretion and reabsorption as water and ions pass between the blood and the filtrate across the tubule membrane. The DCT's are involved in pH Regulation as well as tubular excretion (excretion of Ammonia, Uric Acid, Urea, Creatinine, Hydrogen, antibiotics,and other nitrogenous wastes).Also the distal covulated tubule reabsorve molecules and act whev the body response to loss of water. thank you
