BIOLOGY- EXCRETION- REFERENCE MATERIALS
 
The biological process involved in the removal of harmful metabolic wastes from the body is called excretion.
 
Many unicellular organisms remove these wastes by simple diffusion from the body surface into the surrounding water.
 
Excretion in Human Beings
 
Excretory/urinary system consists of :
 
(1) The kidneys : The excretory organ
 
(2) The ureters : The ducts which drain out urine from the kidneys
 
(3) The urinary bladder : The urinary reservoir
 
(4) The urethra : The channel to the exterior

♦ Formation of Urine
 
• Each kidney contains many filtration units called as nephrons.
 
• Nephrons are made up of a cluster of thin walled capillaries called glomerulus which is associated with a cup like structure called as Bowman’s capsule and the long tube which terminates through this capsule.
 
• The renal artery brings oxygenated blood to the kidneys along with the nitrogenous wastes like urea and uric acid and many other substances.
 
• The blood gets filtered through the glomerulus and this filtrate enters the tubular part of nephron.
 
• As this filtrate moves down the tubular part, glucose, amino acids, salts and excess of water gets selectively reabsorbed by the blood vessels surrounding these tubules.
 
• The amount of water reabsorbed depends upon :
 
* How much excess of water is there in the body and,
 
* How much nitrogenous wastes need to be excreted out.
 
• So the fluid now flowing in the tubular part is urine which gets collected in collecting ducts of nephrons.
 
• These collecting ducts together leave the kidney at a common point by forming the ureter.

→ The urine formation involves three steps :
 
1. Glomerular filtration : Nitrogenous wastes, glucose water, amino acid filter from the blood into Bowman Capsule of the nephron.
 
2. Tubular reabsorption : Now, useful substances from the filtrate are reabsorbed back by capillaries surrounding the nephron.
 
3. Secretion : Urea, extra water and salts are secreted into the tubule which open up into the collecting duct & then into the ureter.
 
Artificial Kidney
 
Haemodialysis : The process of purifying blood by an artificial kidney. It is meant for kidney failure patients.
 
Excretion in Plants
 
Plants use different strategies for excretion of different products :
 
• Oxygen and carbon dioxide is diffused through stomata.
 
• Excess water is removed by transpiration.
 
• Plants can even loose some of their old parts like old leaves and bark of tree.
 
• Other waste products like raisins and gums especially in old xylem cells which can also be lost by plants.
 
• Plants also secrete some waste substances into the soil around them.
