Human excretion is the process by which the body eliminates waste products. This occurs primarily through the digestive system, where food is broken down and nutrients are absorbed. The remaining waste is formed into feces and expelled through the anus during a bowel movement. In addition to feces, the body also excretes waste through urine, which is produced by the kidneys. The kidneys filter blood to remove excess water, salts, and toxins, which are then stored in the bladder until they are released through the urethra. Both processes are essential for maintaining the body's health and balance.
