- proximal tubule :
• Selective reabsorption of nutrients from filtrate back into blood by active and passive transport.
• Within proximal tubule, pH is controlled by secretion of hydrogen ions (H1) and reabsorption of bicarbonate ions (HCO32).
- distal tubule
• Selective reabsorption of nutrients from blood into nephron by active transport. Distal tubule helps regulate potassium (K1) and salt (NaCl) concentration of body fluids.
• As in proximal tubule, pH is controlled by tubular secretion of hydrogen ions (H1) and reabsorption of bicarbonate ions (HCO32).
What else can I help you with?
What are the parts of a nephron in order?
The parts of a nephron in order are the renal corpuscle (glomerulus and Bowman's capsule), proximal convoluted tubule, loop of Henle (descending and ascending limbs), distal convoluted tubule, and collecting duct.
What is the last tubule in the nephron?
The last tubule in the nephron is the distal convoluted tubule. It is responsible for further reabsorption of water and electrolytes, as well as secretion of waste products.
What is the sequence of the nephron in order from glomerular?
From the glomerulus, the sequence of the nephron is proximal convoluted tubule, loop of Henle (descending and ascending limbs), distal convoluted tubule, and collecting duct.
Where does obligatory water reabsorption occur?
Obligatory water reabsorption occurs in the proximal convoluted tubule of the nephron in the kidney. This process helps to maintain the body's water balance by reabsorbing a majority of the filtered water back into the bloodstream.
Where does water reabsorption occur?
Between tubular elements and vascular elements of the nephron beginnings with the proximal convoluted tubule and continuing at least part way into the distal tubule.
What is the primary site of tubular reabsorption in the kidneys?
The distal convoluted tubule or the collecting tube.
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 subdivisons of the renal tubule?
Proximal convoluted tubule, Loop of henle and Distal convoluted tubule.
What are the components of the renal tubule as they are encountered by filtrate?
proximal continuous tubule loop of henle distal continuous tubule
In which region of the nephron does secretion occur?
The distal tubule
What are the parts of a nephron in order?
The parts of a nephron in order are the renal corpuscle (glomerulus and Bowman's capsule), proximal convoluted tubule, loop of Henle (descending and ascending limbs), distal convoluted tubule, and collecting duct.
What is the section of the renal tubule closest to the glomerular capsule?
The proximal convoluted tubule is closest to the glomerular capsule. The distal convoluted tubule is farther away.
What is the last tubule in the nephron?
The last tubule in the nephron is the distal convoluted tubule. It is responsible for further reabsorption of water and electrolytes, as well as secretion of waste products.
In the kidney where does most secretion occur?
Tubular secretion occurs in the distal convoluted tubes. The secretion also happens in the collecting ducts and also in the proximal convoluted tubule.
The portion of the nephron closest to the renal corpuscle is the?
Proximal tubule
What is the sequence of the nephron in order from glomerular?
From the glomerulus, the sequence of the nephron is proximal convoluted tubule, loop of Henle (descending and ascending limbs), distal convoluted tubule, and collecting duct.
