Excretion is the process by which the body removes metabolic wastes and toxic substances produced during cellular metabolism. Proper excretion is essential to maintain homeostasis and internal balance in the body. This chapter explains the structure and function of the human excretory system, including kidneys, ureters, urinary bladder, and urethra. The kidney is the main excretory organ and contains millions of functional units called nephrons. In this class, we cover in detail: • Structure of kidney (cortex, medulla, renal pelvis) • Structure of nephron – Malpighian body, Bowman’s capsule, glomerulus • Renal tubules – PCT, Loop of Henle, DCT, collecting duct • Formation of urine – glomerular filtration, tubular reabsorption, tubular secretion • Role of counter current mechanism in urine concentration • Functions of kidney in osmoregulation and ionic balance • Role of hormones like ADH and Aldosterone • Micturition (urination process) • Disorders of the excretory system – Uremia, Kidney stones, Renal failure, Dialysis This lecture is very helpful for students preparing for Rajasthan Lab Assistant 2026, NEET, and other competitive exams, as every concept is explained in a simple and clear way with diagrams. Watch the full lecture to understand kidney structure, nephron function, and urine formation step by step. 📚 Best for: Lab Assistant Exam 2026 NEET Biology Class 11 Biology (NCERT)
