Which structure contains the capillaries responsible for filtering blood into the nephron? a. proximal convoluted tubule b. bowman's capsule c. loop of henle d. nephron?

b. bowman's capsule 

Filtering is the first step in kidney function. All of the blood component that less than a certain size will be filtered. Filtering is happened in the glomerulus where the blood vessel is convoluted, makes the surface area is higher. The filtered fluid is contained at the Bowman's capsule, then going to the proximal convoluted tubule, then loop of henle
