9 Important Functions of Nephron – Class 10 Read More
Nephrons are the structural and functional units of the kidney.
Each kidney contains a large number of tiny filtration units called nephrons(uriniferous tubules).
Detailed Structure of Nephron Explained with Diagram
Functioning of nephrons Described in points.The functioning of nephron has 3 mechanism to convert blood into urine which are
Filtration
Reabsorption
Secretion
Step By Step process of Functioning of Nephrons is explained with diagram
Nephron is a long coiled tubule whose one end is connected to the double walled cup-shaped structure called Bowman’s capsule and the other end to a urine collecting duct.
Structure and Functioning of Nephron Described with diagram
Excretion removes the unwanted or waste by-products of metabolic pathways which unnecessarily hinder the chemical equilibrium of reactions.Excretion and osmoregulation regulate the ionic concentration of body fluids.
5 Important Significance of Excretion and Osmoregulation Read MoreThe process of regulating water content and ion concentration in the body of an organism is called Osmoregulation.
Osmoregulation is related to the habitat of an organism. In human beings this function is performed by the kidneys.
Egestion – The process involves removing undigested waste food products from the body of the organism.
Excretion – The process involves removing wastes from the cells of organisms.
The biological process of removal of excess or toxic waste products of metabolism from the body of an organism is called Excretion.
EXCRETION IN PLANTS
Excretion in Animals
Excretion in Human Beings
The process of removal of toxic wastes from the body of an organism is called Excretion.
The major Excretory products of Animals are Nitrogenous compounds such as Ammonia, Urea and Uric acid, Bile pigments, Water and Small Amounts of other waste products.
