Pee, or urine, is filtered from the blood by the kidneys, not directly from your digestive system as you might think.
The kidneys serve as efficient filters. Blood circulates through them, where excess water, salts, and waste products are extracted. The end product is urine, which primarily consists of water.
This urine is stored in the bladder until it is ready to be expelled. In some instances, health conditions can hinder the kidneys from filtering effectively.
For instance, diabetes results in elevated blood sugar levels that are filtered into the urine, which can aid in diagnosing the disease.
Essentially, urination is the body’s mechanism for maintaining homeostasis, eliminating unnecessary substances, and providing insights into the functioning of our internal systems.
