The proximal convoluted tubules reabsorb what percentage of filtered water?
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%
Which hormones maintain salt and water balance in the extracellular fluid?
Aldosterone (a mineralocorticoid) regulates water and electrolyte (salt) balance in the extracellular fluid, mainly by regulating sodium ion reabsorption by kidney tubules. Antidiuretic hormone (ADH) causes the distal and collecting tubules of the kidney to reabsorb more water from the urinary filtrate, thereby reducing urine output and conserving body water.
What is removed at the proximal convoluted tubule?
About 90 % of the fitered sodium chlorid in glomerulus is reabsorbed in proximal convoluted tubules.
In which region of the nephron does secretion occur?
The distal tubule
Which anterior pituitary hormone induces ovulation in females and stimulates sex hormone production by the interstitial cells of the testes in males?
A.C.T.H. meansAdrenocorticotrophichormone produced by anterior Pituitary stimulate cortisone production by adrenal cortex in response to 'stress'. Without this response you will not survive.Adrenocorticotropic hormone (ACTH)Acth hypothalus
What hormone secretes the testosterone?
Testosterone IS a hormone. It is secreted by the testes.
What histological feature distinguishes proximal convoluted tubule from a distal convoluted tubule?
Proximal convoluted tubules have brush borders or microvilli on the inner edge of the tubule. Distal convoluted tubules do not have this structure.

Rising blood levels of aldosterone cause the kidney tubules to?
To reabsorb more sodium and some tme that can lead to an edema (oedema)
What Cells make up the convoluted tubules?
All biological tubules [internal linings - convoluted or straight] are made from the same Epithelial Cells that also comprise Our Integument - or Skin.
What is the medical term meaning portion of a nephron that is active in filtering urine?
The Proximal convoluted tubules, descending loop , ascending loop of henle and the distal convoluted tubules. Though the collecting ducts determine the final concentration of urine, an author states that it's not a part of the nephron.
What is removed at the proximal convoluted tubule?
About 90 % of the fitered sodium chlorid in glomerulus is reabsorbed in proximal convoluted tubules.
Where are all the proximal and distal convoluted tubules of the kidney located?
If you are talking about the proximal/distal convoluted tubules. Then you are talking about a kidney, and in between them is the nephron loop or the Loop of Henle
In which region of the nephron does secretion occur?
The distal tubule
The portion of the nephron that is between the proximal and distal convoluted tubules is the?
Loop of Henle
What type of cells form the proximal convoluted tubules?
Simple Cuboidal with Microvilli
