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.
The filters in the kidney prevent blood from entering the urine. When you have hematuria, the filters in the kidneys or other parts of the urinary tract (the kidneys, ureter, and bladder that work together to remove wastes) allow blood to leak into the urine. There are two types of hematuria; microscopic or gross hematuria. Microscopic hematuria means that the blood can only be seen with a microscope. Gross hematuria means the urine appears red or the color of tea or cola to the naked eye. What causes hematuria? Hematuria is common and can have many different causes. These causes include: Inflammation of the kidney, urethra, bladder, or prostate (in men) Abnormal structures in the urinary tract. Inherited diseases, like polycystic kidney disease , sickle cell disease, or hemophilia. Mineral imbalances in the urine.
