1. Internal Organs:

2. 4 quadrants: the torso is divided into into 4 quadrants RUQ LUQ RLQ
LLQ

3. Spleen: acts primarily as a blood filter
similar in structure to a large lymph node
aids in synthesizing antibodies
helps fight infection
it is possible to live without a spleen
LUQ
spleen swells with mononucleosis

4. Liver: filtration system of the body
clears the blood of bad substances
cleans the blood each time it passes through the body
essential organ
mostly in the RUQ but some in LUQ

5. Kidney:
located near your back on either side of the vertebrae. left kidney is posterior to the spleen. right kidney is posterior to the liver
essential in the urinary system and filtration of blood and waste removal
regulates electrolytes and blood pressure
injury can cause blood in urine
you can live without kidneys through dialysis

6. Bladder: collects urine excreted by the kidneys before disposal
storage place
you can live without a bladder but must have an artificial bladder.
midline of RLQ and LLQ

7. Pancreas: produces hormones such as insulin
produces enzymes that break down carbohydrates, proteins, and fats
those with type 1 diabetes have a non properly working pancreas (does not produce insulin)
it is possible to live without a pancreas. must get hormones and enzymes through diet.

8. Gallbladder: storage place for bile not yet being used.
bile aids in the digestion of fats in the small intestine
this is an organ that we can live without.

9. Appendix: no real function in the human body
humans can live without an appendix
