Where does tubular reabsorbtio take plae?
Tubular reabsorption takes place in the renal tubules of the kidney, specifically in the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting ducts. This process involves the reabsorption of filtered substances such as water, ions, and nutrients back into the bloodstream to maintain homeostasis.
What is the controluted tubules?
It seems like there might be a typo in your question. Did you mean "convoluted tubules"? If so, convoluted tubules are found in the nephrons of the kidney and are responsible for reabsorbing water, ions, and other substances from the filtrate back into the bloodstream. They help in maintaining the body's water and electrolyte balance.
Where does formation of urine begin?
Urine formation begins in the kidneys, where blood is filtered to remove waste products, excess ions, and water. This process occurs in the renal corpuscles within the nephrons of the kidney.
What do renal tubes filter?
Renal tubules in the kidney filter waste products, excess ions, and water from the blood to form urine. This process helps in regulating the body's fluid balance and eliminating toxins from the body.
When sodium ions are reabsorbed in response to the action of aldosterone what do potassium ions do?
When sodium ions are reabsorbed in response to aldosterone, potassium ions are often secreted into the urine to maintain electrolyte balance. Aldosterone triggers the reabsorption of sodium in exchange for the secretion of potassium in the distal tubules of the kidney. This mechanism helps to regulate blood pressure and electrolyte balance in the body.
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%

What hormone promotes the reabsorbtion of sodium and potassium ions by the kidney?
When the macula densa in the distal tubules of the kidney sense a decrease in fluid volume, the renin-aldosterone system is activated. Aldosterone is the hormone responsible for sodium retention, causing water to be conserved.
Which ions are exchanged in a sodium potassium pump?
3 sodium ions for 2 potassium ions.

Why sodium level decrease in diebetic patient?
i think this is because of sodium and glucose transporter the transmembrane protein allow sodium ions and glucose to enter the cell together in the same direction and its used to actively transport glucose out of the intestine and out of the kidney tubules back to blood so in case of diabetes sodium cant be reabsorbed in kidney tubules and go to urine and thus sodium level decrease in diabetic patient
What is The forceful movement of waste substances from the blood into the kidney tubules is due to what process?
The forceful movement of waste substances from the blood into the kidney tubules is primarily due to a process called filtration. This occurs in the glomeruli of the kidneys, where blood pressure drives the movement of water, ions, and small molecules from the blood into the Bowman’s capsule, forming the filtrate. This process is crucial for the removal of waste products and the regulation of body fluids and electrolytes.
Where in the kidney does secretion takes place?
Secretion takes place in the renal tubules of the kidney. Specifically, it occurs in the proximal convoluted tubule, distal convoluted tubule, and collecting ducts. These structures are responsible for selectively moving substances like drugs, ions, and waste products from the blood into the urine for excretion.
Do the tubule cells of the kidneys excrete bicarbonate ions and retain hydrogen ions become to acidic?
Yes, the tubule cells of the kidneys can secrete bicarbonate ions and retain hydrogen ions to help regulate blood pH when it becomes too acidic. This process occurs in the renal tubules as part of the kidney's role in maintaining acid-base balance in the body.
