What are the two main components of the solids found in eccrine sweat?

Eccrine sweat is primarily composed of two main components: inorganic salts and organic compounds. The inorganic salts found in eccrine sweat include sodium chloride, potassium, calcium, and magnesium, which play critical roles in maintaining the body's electrolyte balance and overall hydration. The organic compounds include urea, lactate, and various other metabolites, which are important for processes like thermoregulation and skin hydration.

This composition is crucial for the function of eccrine sweat glands, which are responsible for helping the body regulate temperature through the process of evaporation of sweat from the skin surface. Understanding these components allows latent print examiners to consider factors like sweat secretion and residue left on surfaces when analyzing fingerprint evidence, illuminating the potential for identifying individual characteristics based on sweat composition.

Other options, while they may present compounds found in the human body or in various biological contexts, do not accurately reflect the primary composition of eccrine sweat. For example, sugars and lipids are more common in sebaceous secretions, which are different from the fluid secreted by eccrine glands, and proteins, while present in the body, are not the main components of eccrine sweat.
