Yes, skin does excrete urea, primarily through sweat glands.
Urea Excretion Through Sweat
The primary way skin excretes urea is through sweat, which is produced by sweat glands. Here's a breakdown:
- Eccrine Sweat Glands: According to research, urea is excreted in sweat, largely through the eccrine sweat gland.
- Urea Concentration: Interestingly, the urea concentration in human sweat is elevated when compared to blood urea nitrogen, suggesting that sweat is a significant pathway for urea removal from the body.
Therefore, the skin plays a role in the excretion of urea, contributing to the body's overall waste removal processes.
