What else can I help you with?
In which region of the nephron does secretion occur?
The distal tubule
What is the duct that stores urine that has passed through the distal tubule?
The duct that stores urine that has passed through the distal tubule is called the collecting duct. It is part of the nephron in the kidney, where urine is concentrated and further processed before being transported to the renal pelvis. The collecting duct plays a crucial role in regulating water and electrolyte balance in the body.
The sequence of structures that urea passes through in the nephron is?
Urea in the blood is filtered by the glomerulus into the Bowman's capsule, then it travels through the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct. Urea can be reabsorbed and recycled back into the blood at various points along the nephron.
What fluid passes through the renal tubule?
A renal tubule passes most of the fluids it processes into the bloodstream
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.
Which substances are normally secreted into the distal tubule?
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.
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 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.
What are the components of the renal tubule as they are encountered by filtrate?
proximal continuous tubule loop of henle distal continuous 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.
