Covers the microscopic anatomy of the nephron, highlighting the glomerulus and Bowman's capsule as key filtration units.
The glomerulus filters blood, allowing only small molecules like glucose and ions to pass into Bowman’s capsule.

Cortical nephrons have a shorter loop of Henle and are mainly involved in filtration, with limited urine concentration.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
The ascending limb of Henle’s loop is impermeable to water but actively transports electrolytes.

Green glands (also called antennal glands) perform excretory functions in crustaceans like prawns.

The distal convoluted tubule regulates pH balance by selectively secreting hydrogen ions and reabsorbing bicarbonate ions.

Aldosterone is secreted by the adrenal glands, not the pituitary gland.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
The renal corpuscle does not actively secrete hydrogen ions; secretion occurs later in the nephron.

The Loop of Henle plays a key role in maintaining an osmolar gradient, which helps in the concentration of urine.

The distal convoluted tubule helps in maintaining the acid-base balance by selectively secreting hydrogen ions.

The glomerulus is a tuft of capillaries that receives blood from the afferent arteriole for filtration.

The Loop of Henle plays a major role in the counter-current mechanism by maintaining an osmolarity gradient for water conservation.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
The ascending limb of Henle’s loop is impermeable to water but actively transports ions to maintain the osmolarity gradient.
