Final answer:
The tube-like duct that forms the sweat pore is the sweat gland duct. This duct is part of the eccrine sweat glands, which are responsible for regulating body temperature through sweat production.
Step-by-step explanation:
The tube-like duct that ends at the skin surface, forming the sweat pore is the sweat gland duct. There are two main types of sweat glands: eccrine and apocrine. Eccrine glands are found all over the body and their ducts open directly onto the skin surface. Eccrine sweat is primarily water, which helps cool the body when it evaporates.
Apocrine glands, on the other hand, are associated with hair follicles in areas like the armpits and genitals, producing a thicker sweat that can result in body odor when broken down by bacteria. Both types of glands have ducts that transport sweat, but eccrine sweat ends at a pore on the skin's surface, making its duct the correct answer to the question.
