Excretion and nitrogenous waste class 12| Ammonia| Urea| Uric acid| MDCAT Biology|

Aslam O Alekum dears welcome to my You Tube channel ‪@Ziatutorials‬. In this video you will learn the excretion, different types of excretory organs and types of nitrogenous waste such as Ammonia, Urea and Uric Acid. Here's an overview of excretion and nitrogenous waste for Class 12: Excretion Process of removing waste products from the body Includes removal of nitrogenous waste, excess ions, and water Occurs through various organs and systems, including: Kidneys (urine) Liver (bile) Skin (sweat) Lungs (carbon dioxide) Intestines (feces) Nitrogenous Waste Waste products containing nitrogen, such as: Urea (CO(NH2)2) Uric acid (C5H4N4O3) Creatinine (C4H9N3O) Ammonia (NH3) Produced through: Protein metabolism Nucleic acid metabolism Amino acid metabolism Types of Nitrogenous Waste Urea: primary nitrogenous waste in humans, produced in liver and excreted through kidneys Uric acid: produced in liver and excreted through kidneys, primary nitrogenous waste in birds and reptiles Creatinine: produced in muscles and excreted through kidneys Ammonia: toxic nitrogenous waste, converted to urea in liver and excreted through kidneys Excretory Products and their Elimination Urea: urine Uric acid: urine (in humans), feces (in birds and reptiles) Creatinine: urine Ammonia: converted to urea and excreted through kidneys Importance of Excretion Maintains homeostasis Removes toxic waste products Regulates electrolyte balance Helps maintain acid-base balance #excretion #urea #ammonia #uricacid
