Final answer:
Sudoriferous glands, or sweat glands, secrete sweat through a duct to the skin or into a hair follicle. Sweat is composed of mainly water and salts. There are two types of sweat glands: eccrine glands release watery sweat, while apocrine glands release sweat that includes organic compounds and can cause body odor.
Step-by-step explanation:
Sudoriferous glands, also known as sweat glands, secrete sweat through a duct to the skin or into a hair follicle. Sweat is mainly composed of water and salts. There are two types of sweat glands: eccrine glands and apocrine glands. Eccrine glands are coiled glands that release mostly watery sweat, while apocrine glands, associated with hair follicles in densely hairy areas, release sweat that includes organic compounds, making it thicker and subject to bacterial decomposition and subsequent smell.
