The Malpighian corpuscle (renal corpuscle) is structurally composed of which two parts?
According to the NCERT text, 'The Bowman’s capsule encloses the glomerulus to form Malpighian or renal corpuscle.'
Which of the following statements about glomerular filtration is correct?
The text explicitly states, 'Filtration is a non-selective process performed by the glomerulus using the glomerular capillary blood pressure.'
The filtrate formed in Bowman's capsule is largely similar in composition to blood plasma, with the key exception of which component?
Although not directly stated in this excerpt for 'filtration', the comparison to dialysis and common knowledge implies that proteins, due to their large size, are generally not filtered. The text 'Protein-free fluid is filtered from blood plasma into the Bowman’s capsule' from the exercises implicitly supports this.
Which structure in the nephron is a tuft of capillaries responsible for blood filtration?
The text states, 'Glomerulus is a tuft of capillaries formed from afferent arterioles, fine branches of renal artery.'
What is the primary role of the juxta glomerular apparatus (JGA)?
The text says, 'JGA is a special sensitive region formed by cellular modifications in the distal convoluted tubule and the afferent arteriole at the location of their contact. A fall in GFR can activate the JG cells to release renin which can stimulate the glomerular blood flow and thereby the GFR back to normal,' highlighting its role in GFR regulation.
A fall in GFR triggers the release of which substance from JG cells to restore normal GFR?
The NCERT text states, 'A fall in GFR can activate the JG cells to release renin which can stimulate the glomerular blood flow and thereby the GFR back to normal.'
Considering the daily filtrate volume of 180 litres and urine output of 1.5 litres, what percentage of the filtrate is reabsorbed?
The text states, 'A comparison of the volume of the filtrate formed per day (180 litres per day) with that of the urine released (1.5 litres), suggest that nearly 99 per cent of the filtrate has to be reabsorbed by the renal tubules.'
The driving force for glomerular filtration is:
The NCERT text states, 'Filtration is a non-selective process performed by the glomerulus using the glomerular capillary blood pressure.'
Which part of the nephron forms the outer, double-walled cup-like structure that encloses the glomerulus?
The text describes, 'The renal tubule starts with a double walled Bowman’s capsule and is further differentiated... The Bowman’s capsule encloses the glomerulus to form Malpighian or renal corpuscle.'
The afferent arteriole is involved in the formation of which part of the nephron responsible for filtration?
The provided information states, 'Glomerulus is a tuft of capillaries formed from afferent arterioles, fine branches of renal artery.'
