Question

The condition of accumulation of urea in the blood is termed as
(a) Renal Calculi
(b) Glomerulonephritis
(c) Uremia
(d) Ketonuria

Answer 1

Hint: Urea is a nitrogen compound through which excess nitrogen is eliminated from the body of the organisms in the form of wastes. The elimination process is done by the involvement of several organs that help in excretion.

Complete answer
Urea is excreted in the ornithine cycle starting with the two most toxic substances in the human blood. The condition in which urea is accumulated in the blood is called Uremia. This condition occurs when the urea and creatinine are formed as the end products of the amino acids metabolism and they are accumulated in the blood and excreted out through the process of excretion via the kidney and are released outside the body through urine. Urea is said to be the main or primary component that forms the urine.
-Kidney stones also known as the nephrolithiasis is a condition where minerals in the urine form crystals which accumulate and block the urine flow.
-Glomerulonephritis is an autoimmune disease where immune cells attack the kidney, causing inflammation and injury resulting in kidney failure and passage of blood and protein in the urine. Glomerulonephritis is an autoimmune disease where immune cells attack the nephrons, causing inflammation and damage, resulting in kidney failure and passage of blood and protein in the urine.
-Ketonuria is the condition where the urine is composed of several ketone bodies. These ketone bodies use the energy sources during the time when the person is under starvation or is suffering from the diabetes type 1 mellitus.

So, the correct answer is ‘Uremia’.

Note:
Nitrogenous wastes include ammonia, uric acid, and urea. All these various nitrogenous bases are excreted through various organs of excretion that include malpighian tubules, nephridia, and kidneys. The exertion is done in the form of water solutes and various other types of metabolic wastes except for ${ C }{ O }_ { 2 }$. The elimination of these compounds such as ammonia, uric acid, and urea enables the chemical homeostasis of the organism.
