The skin primarily secretes waste through sweat glands. Sweat, or perspiration, is a fluid that contains water, salts, and other waste products. Eccrine sweat glands, the most common type, help regulate body temperature and remove excess water and ions from the body.
While the skin is not the primary organ for waste excretion like the kidneys, it plays a crucial role in removing some waste products. However, sweating is not as effective as other excretory systems, like the kidneys, in removing waste.
