The glomerulus filters blood, allowing only small molecules like glucose and ions to pass into Bowman’s capsule.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans 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.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
Green glands (also called antennal glands) perform excretory functions in crustaceans like prawns.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
The distal convoluted tubule regulates pH balance by selectively secreting hydrogen ions and reabsorbing bicarbonate ions.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
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.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
The Loop of Henle plays a key role in maintaining an osmolar gradient, which helps in the concentration of urine.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
The distal convoluted tubule helps in maintaining the acid-base balance by selectively secreting hydrogen ions.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
The glomerulus is a tuft of capillaries that receives blood from the afferent arteriole for filtration.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Nephron Structure - Glomerulus and Bowmans Capsule
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.
