Answer to Question 1

ANS: C
The ureters are connecting tubes between the kidneys and bladder; they are 4 to 5 mm in diameter, have a 0.2- to 1-cm lumen, and are approximately 25 to 30 cm (12 inches) long.

Answer to Question 2

ANS: C
The purposes of the kidney are to remove metabolic waste, excess substances, and toxic substances from the blood; to regulate and maintain body fluid and pH balance; to help regulate and respond to blood pressure by producing the hormone rennin; to produce the hormone erythropoietin to control the rate at which red blood cells are produced by the bone marrow; and to assist in the production of water-soluble vitamin D, which is important for the metabolism of calcium.
