Another way to understand the difference in concerns between systemic functional grammar and most variants of generative grammar is through Chomsky's claim that linguistics is a sub-branch of psychology . Halliday investigates linguistics more as a sub-branch of sociology.or Halliday, grammar is described as systems not as rules, on the basis that every grammatical structure involves a choice from a describable set of options. Language is thus a meaning potential. Grammarians in SF tradition use system networks to map the available options in a language.
Blood in the urine is medically referred to as hematuria. Hematuria may be visible with the naked eye (gross hematuria) or identified on microscopic urinalysis (microscopic hematuria). Hematuria may be caused by many conditions, and not all causes of hematuria are serious.
Urine that contains blood, known as hematuria, generally possesses a reddish or brownish tinge that is easily identifiable. In some cases, blood may be passed in urine without the tell-tale discoloration, a condition known as a microscopic hematuria. Frequently manifesting in the presence a secondary condition, treatment for a microscopic hematuria is centered on remedying the underlying cause of the bleeding.
