Pee, or urine, is filtered from the blood by the kidneys, not directly from your digestive tract (the system responsible for turning food waste into feces).
The kidneys act as advanced filters, constantly processing blood to remove excess water, salts, and waste chemicals, resulting in urine that is primarily composed of water.
This urine is stored in the bladder until it is expelled. Unfortunately, certain diseases can impair the kidneys’ ability to filter substances effectively.
For instance, diabetes leads to elevated blood sugar levels, which are then filtered into the urine, aiding in the diagnosis of the condition.
In essence, urination is the body’s method for maintaining balance, eliminating excess substances, and providing insight into the efficiency of our internal systems.
