MT 30 LAB – H 3 years, 9 months ago A variety of organs and structures, including the skin, hair, nails, glands, and nerves, are included in the integumentary systems. Its primary function is to protect the internal organs of the body from external contaminants like as pathogens, pollution, and ultraviolet radiation from the sun, among other things. A physical barrier between the exterior and internal environments serves to protect and maintain the body’s internal environment. The integumentary system is the body’s biggest organ, operating as a protective and maintaining mechanism for the internal environment. Along with maintaining the body’s temperature and cell fluid, this system also helps to produce Vitamin D and sense stimuli. It also serves as a barrier against infection.

Apocrine sweat gland is found in the skin, breast, eyelid, and ear. Breast apocrine glands are responsible for the secretion of fat droplets into breast milk, whereas ear apocrine glands contribute to the formation of earwax. Sweat glands are located in the apocrine glands of the skin and the eyelid. The majority of the skin's apocrine glands may be found in the groin, the armpits, and the region that surrounds the nipples of the breasts. The smell glands in the skin are called apocrine glands, and the secretions that these glands produce an odor.
Apocrine sweat glands are typically larger and more productive than eccrine glands. They are characterized by a simple cuboidal epithelium and widely dilated lumen that stores the secretory product. Secretion from apocrine glands contains protein, lipid, carbohydrate, ammonium and other organic compounds.
Your hair follicles are in charge of hair growth, which occurs in cycles with three different stages. The hair type is also determined by these follicles. When follicles are injured, hair production might cease and the hair growth cycle can halt.
The hair follicles are tiny, pocket-like openings in the skin. As their name implies, they produce hair. The typical human scalp has around 100,000 hair follicles.
Because this section of the skin does not have any blood veins, it is reliant on the dermis, which is the layer of the skin that is positioned  beneath the epidermis, to provide it with nutrients and remove waste from its cells.
The epidermis is made up of cells that are of the squamous epithelial type and is stratified. In accordance with the stages of development reached by the cells, the epidermis is composed of four layers:
Stratum germinativum
Stratum spinosum
Stratum granulosum
Stratum corneum
