The skin, through its sweat glands, excretes various waste products from the body. These include:
- Urea: A nitrogenous waste product of protein metabolism.
- Lactic acid: A byproduct of muscle activity.
- Ammonia: A toxic nitrogenous waste product.
- Heavy metals: These can accumulate in the body and are excreted through sweat.
The skin also excretes excess water and salts through perspiration. While the skin plays a role in excretion, it's important to note that the kidneys are the primary organs responsible for removing waste products from the body.
Encouraging sweating through exercise or saunas can be beneficial for supporting excretion pathways.
