During excercise , i think .
the are 3 different respirations but in aerobic the waste product is C02 in anaerobic the waste product from the muscles is lactic acid.
Salt and water are excreted in the form of sweat through the skin.
urine and sweat
are the wastes removed
The waste in your blood is removed by the kidneys. The kidneys filter your blood all day every day

During muscle metabolism, one of the waste products produced is lactic acid, which can build up during exercise and contribute to muscle fatigue. Additionally, carbon dioxide is produced as a byproduct of cellular respiration in muscles, and this waste gas is removed from the body through the lungs when we exhale.
All waste products are removed, they may not go by diffusion alone.
The small intestine takes all the nutrients it needs from the food. Then, all the rest of the food travels down the large intestine and out the other end. The bowel has the job of recovering water from the waste food. Metabolite waste and by-products are removed from the blood by the kidneys. The CO2 is removed from the lungs by breathing. There are a few other waste processes such as excess heat removed by radiation and sweating.
It passes back to the mother through the umbilicus
Carbon dioxide is removed from cells by a process known as diffusion.
