Is the collecting duct the site that drains the distal convoluted tubule?
No, the collecting duct is the site where the filtrate from multiple nephrons is collected and the final adjustments to urine concentration are made. The distal convoluted tubule drains into the collecting duct.
The cells of the distal convoluted tubule which monitor changes in urine volume and osmolarity are called what?
The cells in the distal convoluted tubule that monitor changes in urine volume and osmolarity are known as macula densa cells. They are sensitive to the concentration of sodium chloride in the filtrate passing through the tubule and help regulate blood pressure and fluid balance in the body.
What are the anatomical structures of a nephron?
A nephron consists of a renal corpuscle (including the glomerulus and Bowman's capsule), a proximal convoluted tubule, a loop of Henle (consisting of descending and ascending limbs), a distal convoluted tubule, and a collecting duct. These structures work together to filter blood and create urine in the kidney.
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.
Distal convoluted tubules flow directly into what structures?
The distal convoluted tubules flow directly into collecting ducts within the kidney, where final modifications to the urine occur before it is delivered to the renal pelvis.
