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.
Hematuria is often one of many conditions created by a traumatic injury to the urinary tract, which includes the adrenal glands, kidneys, ureters, bladder, prostate gland and urethra. A sharp blow to the kidneys, for example, can cause blood to enter the bladder. One of the most common causes is kidney disease.
