| Sweat mainly consists of secretions of the eccrine glands. It is the most dilute amongst all the animal fluids. When freshly collected, it contains epithelial cells and some sebum. When filtered, it forms a clear colorless fluid. The human sweat has specific gravity of about 1.001-1.006 and a pH of 3.8 to 6.5. | | Sweat mainly consists of secretions of the eccrine glands.
