Which of the following parts of the mammalian skin is directly is directly involved in excretion?
Answer Details
The sweat gland is directly involved in excretion in the mammalian skin.
Sweat glands are tiny, coiled glands located in the dermis layer of the skin that produce sweat, which is mostly composed of water, salt, and urea. Sweat glands are an important part of the excretory system, as they help to regulate body temperature by releasing sweat onto the skin's surface, where it evaporates and cools the body.
In addition to regulating body temperature, sweat glands also help to remove waste products from the body. Urea, a nitrogen-containing compound that is a byproduct of protein metabolism, is excreted through sweat. This helps to maintain the balance of electrolytes and other substances in the body.
Sebaceous glands, on the other hand, produce an oily substance called sebum that helps to lubricate and protect the skin and hair. The horny layer is the outermost layer of the epidermis that helps to protect the skin from damage. Hair follicles are structures that grow hair and are located in the dermis layer of the skin. The Malpighian layer is a layer of cells located between the dermis and epidermis that is responsible for the production of new skin cells.
