### process:

Excretion
* Most excretion contains substances
  - depends on diets
  - involves movement
  - occurs in kidneys
  - refers to metabolism
  - reflects renal damage
  - removes materials
* Most excretion removes metabolic products
  - waste products
* Most excretion removes waste materials
  - triggers allergic reaction
* Some excretion affects infants
  - attracts bees
* Some excretion causes accumulation
  - deterioration
  - drug accumulation
  - decreases with ages
  - exceeds nocturnal excretion
* Some excretion goes through bile ducts
  - has water
* Some excretion increases ingestion
* Some excretion interferes with absorption
  - iron absorption
* Some excretion is produced by adults
  - aphids
* Some excretion occurs in digestive tracts
  - dogs
  - individuals
  - loose stools
  - plants
  - the digestive tract and some via milk
  - produces acid
* Some excretion promotes bile acid synthesis
  - growth
* Some excretion relies on diffusion
  - passive diffusion
* Some excretion represents energy
  - magnesium metabolism
* accounts for excretion.
* also takes place in the gut, skin, lungs, sweat glands, breast and salivary glands.
* applies to metabolic waste products that cross a plasma membrane.
* begins with the kidneys.
* cleans up after respiration.
* completes the process of food handling.
* consequence of hunger satisfaction.
  - intake
* follows consumption
* forms in intestines.
* has effects.
* includes the disposal of nitrogen-containing waste products.
* involves filtration onto the coelom and reabsorption and secretion in the nephridium
* is accomplished by Malpighian tubules and a pair of coxal glands
  - coxal glands and Malpighian tubules
  - via a single pair of Malphigian tubules and a pair of maxillary glands
  - an emblem of our fallen condition, of our guilt
  - any process which gets rid of unwanted metabolic products
  - as the glucuronide of artenimol, principally in the faeces and urine
* is carried out by a pair of nephridia, who empty their contents into the mantle cavity
  - of protonephridia
  - one special organ in human body called Kidney
  - paired nephridia that empty into a duct shared with the gonads
  - mainly by the kidneys
  - chiefly by the kidneys through glomerular filtration and tubular secretion
  - decreased in moderate liver or renal impairment
  - discharge
  - done by nephridia and feeding by adhesive tentacles called captacula
  - handled by tubular nephridia, with one pair of nephridia in each segment
* is important to get rid of the waste products
  - remove harmful waste substances from the blood
  - made through the rectum and then empties through the anus
  - mainly renal, with no apparent excretion of unchanged drug
  - one of the most basic functions of life
  - performed by Malpighian tubules
  - slower if the urine is alkaline
* is the elimination of excess ions, water, and metabolic wastes from the body
  - waste from the body
  - expulsion of excess water and wastes
  - getting rid of metabolic waste products
* is the process by which the body rids itself of waste products resulting from metabolism
  - metabolic waste products are removed from the plant body
  - wastes are removed from the body
* is the process of eliminating waste products of metabolism and other non-useful materials
* is the process of removing cellular metabolic wastes from the body
  - that removes waste products of metabolism from the body
  - through which metabolic wastes are removed from the body
* is the removal of material from a living thing
  - potentially harmful or toxic substances from the body
  - substances from plants, animals and other living organisms
* is the removal of waste materials produced by the reactions of the body
  - products made by the body
  - watse from an organism
* is through a separate excretory pore
  - small ducts known as metanephridia
* is through the kidneys if the blood levels are too high
  - urine, feces, and sweat
  - via protonephridia
* keeps the body's internal environment stable and free of harmful materials.
* life process.
* occurs at the cell level into water.
  - the feces
  - mainly via the urine
* occurs primarily by biliary and renal routes
  - in the urine and is and pediatric patients taking
  - relatively rapidly with no evidence of accumulation
* refers to the processes by which the body eliminates a drug
  - removal of metabolic wastes produced in the body
* reflects damage
* shows trends.
* takes place in the Malphigian bodies located in the renal cortex of the kidney.
