Question

filtering of the blood begins in the ______
○ bowmans capsule
○ ureter
○ bladder
○ nephrons

Explanation:

To solve this, we analyze each option:

• Bowman’s capsule: Part of a nephron, where blood filtration (glomerular filtration) starts.
• Ureter: Transports urine from kidney to bladder, not for filtration start.
• Bladder: Stores urine, no filtration role.
• Nephrons: The functional units of the kidney, but filtration begins specifically in Bowman’s capsule (a part of nephron). So the correct answer is Bowman’s capsule.

Answer:

A. Bowman's capsule
