what is the difference between fundamental quantities from derived quantities? Nature itself doesn't have fundamental or derived quantities. We have choices of units with more or less direct ties to things we measure. In modern systems of units, we try to simplify things by making units for different quantities have simple relations.
The left lower quadrant (LLQ) contains the distal descending colon, the sigmoid colon and the left ureter. Depending on the sex of the individual, both the left and right lower quadrants contain either an ovary, a uterine tube, a ductus deferens, the uterus and the urinary bladder.
The four abdominal quadrants are located in the space directly below the diaphragm. These regions are referred to based on their location: the right upper quadrant (RUQ), right lower quadrant (RLQ), left upper quadrant (LUQ), and left lower quadrant (LLQ).Now, let's take a look at each of these areas.n the LUQ you'll find the left portion of the liver, the majority of the stomach, pancreas, left kidney, spleen, portions of the colon, and (again) parts of the small intestine. Much like the RUQ, the organs contained in this section are also very important.
