What is urine?

Liquid waste from the kidneys
Stomach acid
Blood cells
Feces

The correct answer is: Liquid waste from the kidneys

Urine is defined as the liquid waste product that is produced by the kidneys as part of the process of filtering and removing waste and excess substances from the bloodstream. The kidneys play a crucial role in maintaining the body’s fluid balance, electrolyte levels, and overall homeostasis by producing urine. This process involves the filtration of blood, where harmful substances and excess water are extracted to form urine, which is then stored in the bladder until it is excreted from the body. The other options represent different bodily substances or processes: stomach acid is involved in digestion, blood cells are crucial for transport and immune functions, and feces result from the digestion of food, related to waste expelled from the gastrointestinal tract rather than directly from kidney function.
