Focuses on disorders affecting urine elimination and the functions of accessory excretory organs like the skin, liver, and lungs. Includes common conditions and their physiological basis.
Uremia is a condition in which urea accumulates in the blood due to kidney failure.

Kidneys are the primary excretory organs that remove nitrogenous wastes and help in osmoregulation.

The lungs excrete carbon dioxide, a waste product of cellular respiration, through exhalation.

The liver plays a key role in excretion by removing toxins and excreting bile pigments.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Micturition Disorders and Accessory Excretory Organs
The liver detoxifies substances and excretes bilirubin as bile pigments.

Renal calculi (kidney stones) are formed due to the crystallization of salts like calcium oxalate in the kidney.

The lungs play a key role in excreting CO₂, a waste product of cellular respiration, through exhalation.

Hemodialysis is used to remove waste and excess fluids from the blood in patients suffering from kidney failure.

The lungs excrete carbon dioxide, which is a byproduct of cellular respiration.

The liver detoxifies substances and excretes bilirubin as bile pigments.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Micturition Disorders and Accessory Excretory Organs
The lungs primarily excrete carbon dioxide, not nitrogenous waste.
