Final answer:
Option (c), Sudoriferous glands are known as sweat glands and their primary function is to secrete sweat, comprised of water, salts, and waste, to cool the body.
Step-by-step explanation:
The sudoriferous glands, also known as sweat glands, secrete c. sweat. These glands play a crucial role in thermoregulation, which is the body's process of maintaining its internal temperature. When the body becomes warm, the sudoriferous glands produce sweat, a fluid composed of water, salts, and other waste products, to cool the body through evaporative cooling.
In contrast, sebaceous glands secrete sebum, a lipid-rich substance that waterproofs and lubricates the skin and hair. Sebum also has antibacterial properties, helping to keep the skin free from microorganisms. Sweat glands and sebaceous glands have different functions and secretions, although both contribute to maintaining the skin's health.
There are two types of sweat glands: eccrine and apocrine. Eccrine glands are present throughout the body and are responsible for secreting the watery sweat, while apocrine glands are associated with hair follicles and are responsible for secreting a thicker sweat that plays a role in communication, often related to scent.
