Sebaceous Glands vs. Sweat Glands

Main Difference

The main difference between Sebaceous Glands and Sweat Glands is that sebaceous gland is a small gland in the skin which discharges a lubricating oily matter (sebum) into the hair follicles to grease the skin and hair whereas sweat glands are a type of exocrine gland, that produce and discharge materials onto an epithelial surface by way of a duct.

Difference Between Sebaceous Glands and Sweat Glands

Sebaceous Glands vs. Sweat Glands

Sebaceous glands discharge sebum into hair follicle whereas sweat glands secrete sweat.

Sebaceous Glands vs. Sweat Glands

Sebum is an oily matter on the other hand sweat is a sticky and odorous substance.

Sebaceous Glands vs. Sweat Glands

Sebaceous glands are present in the body except for palms and soles on the flip side sweat glands are present in the ear, armpits, areola, eyelids, and external genitalia.

Sebaceous Glands vs. Sweat Glands

Only one type of sebaceous glands are present in the skin oppositely eccrine sweat glands, and apocrine sweat glands, are the two types of glands present in the skin.

Sebaceous Glands vs. Sweat Glands

Sebaceous glands discharge oily or waxy matters, but sweat glands release sticky and odorous substances.

Sebaceous Glands vs. Sweat Glands

The secretion of the sebaceous glands is comprising of lactic acid, glucose, traces of urea, amino acids, sodium chloride, and water while the secretion of the sweat glands is establishing of fatty acids and hydrocarbons.

The primary function of the sebaceous glands is lubrication whereas the central feature of the sweat glands is to regulate the temperature and excretion.

Sebaceous Glands vs. Sweat Glands

Sebaceous glands discharge sebum into hair follicle whereas sweat glands discharge sweat. Sebum is an oily material while sweat is a sticky and odorous substance. Sebaceous glands are existing throughout the body except for palms and soles whereas sweat glands are present in the ear, eyelids, armpits, areola, and external genitalia. Only one type of sebaceous glands is present in the skin whereas apocrine and eccrine sweat glands are the two types of glands present in the skin. Sebaceous glands discharge sebum whereas sweat glands discharge sweat. Sebaceous glands release oily or waxy matters whereas sweat glands secrete sticky and odorous substances. The secretion of the sebaceous glands is constituting of lactic acid, glucose, amino acids, and traces of urea, sodium chloride and water whereas the secretion of the sweat glands is representing of fatty acids and hydrocarbons. The principal function of the sebaceous glands is lubrication whereas the primary feature of the sweat glands is to regulate the temperature and excretion.

What is Sebaceous gland?

Sebaceous glands are the insignificant glands in the skin and constitute of epithelial cells that secrete lubricating oily matter, sebum into hair follicles on our body. It utilizes oily fluids and a fatty material known as “sebum.” They are branch, acinar (spherical) glands present in mammals. These glands are copious mostly in the face and scalps of human, but they can present on the entire body. They cannot give in our palms and soles. The sebum is a fatty acid substance, secreting into the follicular duct and then to the external of the skin. The round cells in the sebaceous gland are filling with lipid vacuoles. These cells degenerate to discharge the contents into the duct. This sort of secretion in exocrine glands is referring to as holocrine secretion — the sebum coverings the hair and the surface of the skin to retain it’s soft and waterproof. The size and the secretory action of the sebaceous glands rise at puberty, with the increasing levels of androgens in the body. When a sebaceous gland is a block, the produce sebum is might into the dermis and may cause an inflammatory response, causing acne. The main functions of sebaceous gland secretions’ are to waterproof the body and lubricate the hair.

What is Sweat gland?

Sweat glands are the small glands in the membrane which produce sweat and possess a simple tubular structure. Sweat is a watery liquid that is hypotonic to the plasma. The vaporization of the sweat is necessary for thermoregulation. Sweat is comprising of water, urea, sodium chloride, and lactic acid. Sweat glands are present in the shallow hypodermis near the border of the dermis. The duct of the sweat gland is a coil structure. It opens to the skin as a sweat pore. The apocrine sweat glands and eccrine sweat glands are the two types of sweat glands in the skin. Sweat’s primary function is to defend the skin from severe dryness. Sweat also serves the purpose of inhibiting bacteria from entering the sacs of human skin. We can easily wash off all the dust on our skin, mainly when the process of sweating occurs. There are two types of sweat glands. Eccrine sweat glands help as a cooling agent for the human body by utilizing the sweat excreting to make the body cool off through evaporation. Apocrine sweat glands are the sweat sacs present in our armpits and perianal parts. They also help to cool the human body. These glands are larger and are more real in animals than in humans.

Conclusion

Above this discussion, it concludes that sebaceous glands and sweat glands are the two types of exocrine glands present in the skin. Sebaceous glands discharge sebum that lubricates the surface of the skin whereas sweat glands release sweat that is responsible for the control of thermoregulation and excretion.
