Eccrine sweat glands are described as which structure that secretes directly onto the skin?

Explanation:
Eccrine sweat glands are organized as a simple coiled tubular gland that secretes its watery product directly onto the skin surface. The secretory portion sits in the dermis and forms a coil, with a duct that carries sweat to the epidermal surface. This coiled tubular arrangement maximizes secretory surface area in a compact space and distinguishes eccrine glands from branched (acinar) or alveolar glands, which would have sac-like expansions. Therefore, the description that best fits is a coiled tubular structure.
