The fluid that leaves the glomerulus and enters the glomerular capsule is called glomerular:

• A. filtrate
• B. urine
• C. plasma
• D. secretion

Answer: (A)

Verified step by step guidance

1. Understand the function of the glomerulus: The glomerulus is a network of capillaries in the kidney that filters blood. It allows water, ions, and small molecules to pass through while retaining larger molecules like proteins and blood cells.
2. Define the term 'glomerular filtrate': The fluid that passes through the glomerular capillaries and enters the glomerular capsule is called glomerular filtrate. It contains water, ions, glucose, amino acids, and waste products but lacks large proteins and blood cells.
3. Differentiate between the options: 'Urine' is the final product of filtration, reabsorption, and secretion in the nephron, not the initial fluid. 'Plasma' refers to the liquid component of blood, which is filtered to form the glomerular filtrate. 'Secretion' is a process in the nephron where substances are added to the filtrate, not the initial fluid.
4. Recognize the correct term: The fluid that leaves the glomerulus and enters the glomerular capsule is specifically referred to as 'glomerular filtrate,' as it is the result of the filtration process.
5. Apply the concept: When answering questions like this, focus on the stage of kidney function being described. In this case, the initial filtration process produces glomerular filtrate, not urine or plasma.
