The ions that are secreted by the distal convoluted tubule are potassium ions. These are secreted to better control the levels of potassium and sodium.

Function of distal tubule?
The distal tubule reabsorbs ions into the tubular fluid. The distal tubule plays a huge role in the balance of acid in the urinary tract.
Why is ADH secreted?
It is secreted when the body senses and increase in osmolarity, like in dehydration. It creates aqua-porins in the distal tubule in the kidneys to increase water reabsorption.
The hormone ADH functions to promote water re-abdsorption through the wall of what in the kidney?
distal convoluted tubule and collecting duct.The distal convoluted tubule
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.
Is the distal tubule and collecting ducts relatively impermeable due to water in the absence of hormones?
In the absence of hormones, the distal tubule and collecting ducts are relatively impermeable to water. True
In which region of the nephron does secretion occur?
The distal tubule
Function of distal tubule?
The distal tubule reabsorbs ions into the tubular fluid. The distal tubule plays a huge role in the balance of acid in the urinary tract.
What is the primary site of tubular reabsorption in the kidneys?
The distal convoluted tubule or the collecting tube.
What are the subdivisons of the renal tubule?
Proximal convoluted tubule, Loop of henle and Distal convoluted tubule.
What is the last portion of the renal tubule?
the three main portions of the renal tubule are the proximal convoluted tubule, the loop of henle, and the distal convoluted tubule. the proximal convoluted tubule is the first portion. The proximal (convulated) tubule.
What are the components of the renal tubule as they are encountered by filtrate?
proximal continuous tubule loop of henle distal continuous tubule
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.
Why is ADH secreted?
It is secreted when the body senses and increase in osmolarity, like in dehydration. It creates aqua-porins in the distal tubule in the kidneys to increase water reabsorption.
The hormone ADH functions to promote water re-abdsorption through the wall of what in the kidney?
distal convoluted tubule and collecting duct.The distal convoluted tubule
Where does ADH act on the nephron?
collecting duct (system) and late distal tubule
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.
What is finally reabsorbed in distal convoluted tubule?
Bicarbonate.
