Chapter 26, Problem 16RFT
Summary Introduction
Introduction:
The kidneys are the important organ of the excretory or the urinary system. It helps in the excretion of the waste substances, such as nitrogenous waste from the body. The excretory system performs the filtration of the blood in order to separate out the waste substances from the blood and also aid in the reabsorption of the important substances.

The filtrate leaving the glomerular capsule empties into the (a) distal convoluted tubule. (b) nephron loop. (c) proximal convoluted tubule. (d) collecting duct.
The primary purpose of the collecting system is to (a) transport urine from the bladder to the urethra. (b) selectively reabsorb sodium ions from tubular fluid. (c) transport urine from the renal pelvis to the ureters. (d) make final adjustments to the osmotic concentration and volume of urine.
The distal convoluted tubule is an important site for (a) active secretion of ions. (b) active secretion of acids and other materials. (c) selective reabsorption of sodium ions from the tubular fluid. (d) a, b, and c are correct.
