Body cells are not excreted like waste products. Instead, cells undergo programmed cell death (apoptosis) when they age or become damaged. The body then breaks down and recycles these cells through processes like phagocytosis or autophagy.
When old red blood cells are destroyed, the waste product formed is bilirubin. Bilirubin is processed in the liver, conjugated with glucuronic acid, and then excreted into bile. The bile containing bilirubin is eventually excreted from the body through the feces.

Urine is excreted from the body through the urethra, which is a tube that connects the bladder to the genitals for elimination.
Bilirubin is produced by the liver as a byproduct of the breakdown of red blood cells. It is then excreted into bile and eventually eliminated from the body through the feces.
Fat-soluble vitamins are stored in the body's fat tissues, while water-soluble vitamins are excreted in urine when in excess since the body does not store them. This is because fat-soluble vitamins can be stored in fat cells and released when needed, while water-soluble vitamins are readily excreted when the body has enough.

Blood cells produce it, then the kidneys or your liver and liver store it in your lower abdomen until it's excreted from your body.
The erythrocytes, or red blood cells as they are more commonly known as, transport oxygen to the body's cells and extract the carbon dioxide and send it to the lungs to be excreted.
Worn out red blood cells are removed by the spleen, liver, and bone marrow. The cells are broken down and their components are recycled or excreted from the body. This process helps maintain the appropriate level of healthy red blood cells in circulation.
Urethra
Perspiration is the liquid body waste excreted by the sweat glands in the dermis of the skin.
Citric acid in your cells are essential for your body to help provide energy. Citric acid is also a common additive to foods which will be consumed into the bloodstream and then excreted from the body.

Many materials are excreted from the body. These include carbon dioxide, nitrogenous wastes, and undigested food waste.
