THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Creatinine is a by-product of muscle metabolism in which creatine in the muscle is converted nonenzymatically to creatinine. Because the total body content of creatine is fairly constant, there is a continual production of creatinine and a continual excretion of it in the urine.

Detailed explanation-2: -Creatinine is synthesized in the liver and transported to several parts like muscles and brain. This product is further transformed to high energy compound called phosphocreatine, which undergoes catabolism to give energy and end product as creatinine which is excreted by the kidney.

Detailed explanation-3: -Creatinine is a chemical waste product of creatine. Creatine is a chemical made by the body and is used to supply energy mainly to muscles. This test is done to see how well your kidneys work. Creatinine is removed from the body entirely by the kidneys.
