Glucose reabsorption occurs mainly in the proximal convoluted tubule, not in the collecting duct.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
ADH regulates water reabsorption in the kidneys, helping to concentrate urine.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
Creatinine is not reabsorbed by the nephron and is completely excreted in urine.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
The counter-current mechanism in the Loop of Henle and vasa recta helps concentrate urine and conserve water.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
The Loop of Henle establishes an osmotic gradient, which helps in water reabsorption and urine concentration.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
ADH increases water reabsorption in the kidney, reducing urine output and preventing dehydration.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
The collecting duct plays a major role in concentrating urine by reabsorbing water under the influence of ADH.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
The renal vein carries deoxygenated but filtered blood away from the kidney.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
The renal corpuscle (Bowman’s capsule + glomerulus) is responsible for ultrafiltration of blood.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
The descending limb of Henle’s loop allows water reabsorption but is impermeable to electrolytes.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
ADH does not promote sodium excretion; it regulates water reabsorption to prevent dehydration.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
ADH increases the permeability of the collecting ducts, allowing more water reabsorption and reducing urine volume.
