Question

Kidneys are made up of number of filters called _______.

• A. Nephrons
• B. Glomerulus
• C. A and B
• D. None of the above

Answer 1

The correct option is A Nephrons

Each of kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

Hence, the correct answer is (A)
