Sweat glands - Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor, meaning 'sweat', are small tubular structures of the skin that produce sweat. Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct.
Dermis - The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.
Oil gland - Sebaceous glands are microscopic exocrine glands in the skin that secrete an oily or waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals. Sebaceous glands produce an oil called sebum, which is thought to play a role in keeping your skin moist. Sebaceous glands are located next to individual hairs in sebaceous follicles. The hormones that cause body changes at puberty also cause the sebaceous glands to produce more oil.
Epidermis - the surface epithelium of the skin, overlying the dermis or he outer layer of tissue in a plant, except where it is replaced by periderm.
