Which findings are within expected parameters of a normal urinalysis?

Ketone bodies are byproducts of incomplete metabolism of fatty acids. Normally, there 
are no ketones in urine. Ketone bodies are produced when fat sources are used instead of 
glucose to provide cellular energy. The abnormal values are indicative of a urinary tract infection. As a result of protein, nitrates, and leukoesterase in the urine, the nurse can expect the laboratory to 
analyze microscopic sediment including evaluating the sample for the presence of 
crystals, casts, WBCs, and RBCs.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
