The document discusses excretion in humans and other organisms. It describes the human urinary system, which includes the kidneys, ureters, bladder and urethra, as the main organs that remove nitrogenous wastes like urea from the bloodstream in the form of urine. The kidneys play an important role in homeostasis by filtering blood and regulating the levels of water, salts and other substances in the body. Wastes pass through nephrons in the kidneys and exit as urine through the ureters to the bladder. Plants remove gaseous wastes like carbon dioxide through stomata and transpire excess water in the same way.
Life process excretion

- 2. Life Processes Life processes are the basic processes in living organisms which are necessary for maintaining their life. The basic life processes are :- 1.Nutrition
- 3. ExcretionBiological process of eliminating metabolic waste substances is called excretion. Human excretory system consists of a pair of kidney and a pair of ureter, a Urinary bladder and a urethra. In unicellular organism the waste products are removed
- 4. Human Excretion Like other animals, humans have a system that excretes Nitrogen wastes such as Urea, salt, and water. Urinary System : Kidneys, ureter, urethra, and bladder. Kidneys (located in back) play important role in homeostasis :-
- 6. How The Kidneys Work ??1. Blood enters kidneys from renal artery. 2. Blood is filtered by passing through millions of nephrons. 3. Wastes pass through ureter to the bladder as urine. 4. Clean blood returns to body
- 7. The NephronEach nephron has a cup like structure called Bowmans capsule containing a bundle of capillaries called glomerulus. The Bowmans capsule leads into a tubular structure which joins into a collecting duct. The renal artery brings the nitrogenous waste along with excess water, salts etc. into the
- 9. Plants Excretion In plants the gaseous waste products produced during respiration (CO2) and photosynthesis (O2) are removed through the stomata. Excess water is removed through the stomata. This process is called transpiration. Some waste products are stored in the leaves and removed when the .
