In nephron what is the fluid that precedes urine?
The fluid that precedes urine in the nephron is called tubular fluid.
What is Active transport of substances from the blood into the nephron called?
Tubular secretion
The active transport of penicillin from the blood into the nephron is an example of the process of?
tubular secretion
Where does obligatory 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 tubular excretion?
Very generally, excretion is the removal of substance from the body (micturition or defecation are good examples). Tubular excretion is probably referring to excretion of (filtrate, now urine) from the collecting duct of a nephron. Beyond the collecting duct, almost no secretion or absorption occurs, hence all substrate is excreted (NOT the same as secreted).
In nephron what is the fluid that precedes urine?
The fluid that precedes urine in the nephron is called tubular fluid.
What is tubular load?
The total amount of a substance that enters the tubular portion of the nephron each minute is said to be tubular load.
What are the three basic process that occur in the nephron?
Filtration, tubular reabsorption, tubular secretion
What is Active transport of substances from the blood into the nephron called?
Tubular secretion
The active transport of penicillin from the blood into the nephron is an example of the process of?
tubular secretion
The process by which the renal tubule actively moves substances from the blood into the nephron to be excreted?
Tubular secretion
What is the function of tubular reabsorption?
Tubular reabsorption is the movement of filtrate from renal tubules back into blood in response to the body's specific needs.

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.

Can diuretics have an affect on tubular function in the nephron?
Diuretics are medicines which relieve water retention in the body by increasing urination. This effect includes an increase in sodium and bicarbonate in the urine, due to the effect on the reabsorption function of the nephron.
Can the reabsorption of solutes influence water reabsorption in the nephron?
Yes, The movement of solutes into peritubular capillaries decreases the solute concentration of the tubular fluid but increases the solute concentration in the peritubular capillaries. As a result, water moves by osmosis into peritubular capillaries.
What are the three steps of urine formation and in what part of the nephron does each occur?
Urine formation and the adjustment of blood composition involve three major processes: glomerular filtration by the glomeruli, and tubular reabsorption and tubular secretion in the renal tubules. In addition, the collecting ducts work in concert with the nephrons to concentrate or dilute the urine..Functions of the nephrons include filtration, tubular reabsorption, and tubular secretion. Via these functional processes, the kidneys regulate the volume, composition, and pH of the blood, and eliminate nitrogenous metabolic wastes.
