Secretion is an active process. In the kidney tubules, somethings, like K+ is secreted from the peritubular capillaries, into tubular cells, and then out into the lumen to mix with the fluid.
Excretion is passive. What is excreted by the kidneys is everything that is not reabsorbed and what is secreted. So that means, after all the re-absorbing and secreting processes of the cells, everything that's left in the tubules is excreted into the urine.

What is obligatory water excretion?
Obligatory water excretion refers to the minimum amount of water that the body needs to eliminate to maintain proper functioning. This is necessary to remove waste products and maintain electrolyte balance. The kidneys regulate obligatory water excretion through processes such as filtration, reabsorption, and secretion.
Excess blood potassium hyperkalemia is removed by increasing secretion of the hormone which stimulates an increase in the secretion of potassium by cells within the?
Excess blood potassium (hyperkalemia) is typically removed by increasing the secretion of aldosterone. Aldosterone stimulates the kidneys to increase the secretion of potassium by cells within the kidney nephrons, promoting the excretion of excessive potassium from the body through urine.
Where is the primary site at which tubular secretion occur?
Tubular secretion is a part of urine formation occurring within the nephrons of the kidneys. After glomerular filtration, in which fluids from the blood pass into the glomerular capsule of the renal tubule, the filtrate is subject to tubular reabsorption and tubular secretion within the convoluted tubules and collecting ducts of the nephrons.
What is the difference between osmoregulation and excretion?
Osmoregulation is the maintenance of the amounts of water and salts in body fluids. Excretion is a process of homeostasis. In this process,nthe metabolic wastes are eliminated from body to maintain the internal conditions at equilibrium.
In which region of the nephron does secretion occur?
The distal tubule
What rhymes with excretion?
Secretion? Extinction? Mastication?
What are the four steps of excretion?
The four steps of excretion are filtration, reabsorption, secretion, and excretion. Filtration involves separating waste products from blood, reabsorption allows for the reabsorption of useful substances back into the blood, secretion involves additional waste products being added to the filtrate, and finally, excretion is the removal of the final urine or feces from the body.
What is the difference between excretion and defecation?
The difference between excretion and defecation is excretion is the removal of waste and defecation is the removal of undigested waste. During defecation, the nutrients are absorbed by the body before being removed from the body.
What are three different functions of the kidneys?
excretion, filtration and secretion!
What are the function of epithelium?
protection, absorption, filtration, excretion, secretion, and sensory reception
What is The rate of urinary excretion of any solute is equal to?
The rate of urinary excretion of any solute is equal to the rate of filtration minus the rate of reabsorption plus the rate of secretion in the nephron. This process determines the amount of a solute that is eliminated in the urine.
What is the processes of cell?
nutrition, digestion, absorption, biosynthesis, respiration, secretion, response, reproduction, excretion, movement

What is the difference between excretion and transpiration in plants?
When plants transpire, it is the process of excretion for them. They use the carbon dioxide from animals to make energy, and let out water vapor, or transpire, as a result.
What is the difference between hypersecretion and hyposecretion?
Secretion is the process of elaborating, releasing, and oozing chemicals, or a secreted chemical substance, from a cell or gland. In contrast to excretion, the substance may have a certain function, rather than being a waste product. Hypersecretion means producing more of these chemicals than what is considered normal or average; in other words, excessive secretion. Hyposecretion means producing less of these chemicals than what is considered normal or average; in other words, undersecretion.
How undigested food are excreted in cockroach?
Cockroaches have malpighian tubules which are the secretion organs. Digested food is passed to the organs which then expels it from the insect.
What is absorption in shapes v functions of the skin?
Sensation Heat Regulation Absorbtion Protection Excretion Secretion Vitamin D
