Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What toxic substance is excreted in the urine?
A
Glucose
B
Sodium ions
C
Carbon dioxide
D
Urea
Explanation: 

Detailed explanation-1: -The uric acid, urea and ammonia are the main excretory products. Accumulation of ammonia can be very dangerous for the body. Hippuric acid is the normal component of the urine. Mammals excrete urea.

Detailed explanation-2: -Some of these chemical byproducts such as Ammonium and Urea can be harmful if they accumulate in the body and the kidneys excrete these waste products as chemicals in the urine.

Detailed explanation-3: -Amino acids may also be metabolized through the liver to form urea, which is then excreted in the urine. Body protein stores can be converted back to essential and nonessential amino acids or may be metabolized, forming waste products and ions, which, as previously detailed, are excreted in the urine.

Detailed explanation-4: -Urea, the major end product of protein metabolism in mammals, is the most abundant solute in the urine. Urea excretion is thought to result from filtration curtailed by some passive reabsorbtion along the nephron.
