As a subject matter expert in human physiology, I can explain the process of waste removal from the human body. The body has several systems in place to eliminate waste products generated from cellular metabolism and external substances.
Urinary System: The primary means of waste removal is through the urinary system. Waste products such as urea, which is a byproduct of protein metabolism, are filtered out by the kidneys. The kidneys also regulate the balance of water and electrolytes in the body. The waste is then excreted through the ureters to the bladder, where it is stored until it is eliminated from the body through the urethra during urination.
Respiratory System: Carbon dioxide, a waste product of cellular respiration, is removed through the respiratory system. The gas is carried from the cells to the lungs via the bloodstream, where it is expelled from the body when we exhale.
Skin: The skin also plays a role in waste removal, primarily through the process of sweating. Sweat contains water, salts, and small amounts of other waste products. When sweat evaporates from the skin's surface, it takes these waste materials with it.
Digestive System: The digestive system is responsible for the elimination of solid waste, or feces, which consists of undigested food, bacteria, and other waste materials. After digestion, the remaining waste is moved through the large intestine to the rectum and then expelled through the anus during defecation.
Lymphatic System: The lymphatic system helps to remove waste products from the body's tissues, particularly fats and cellular debris, and carries them to the bloodstream to be eliminated.

Removing waste products. Waste products are constantly being produced by the body and must therefore be excreted. If they are not, they will increase in concentration and may interfere with chemical reactions or damage cells. Waste products that must be removed include carbon dioxide and urea.
