Pituitary gland
The cell glands that release their secretions by rupturing are known as holocrine glands. In holocrine secretion, the entire cell disintegrates to release its contents, which includes both the secretion and cellular debris. An example of a holocrine gland is the sebaceous gland, which produces oil for the skin and hair. This method of secretion contrasts with merocrine and apocrine glands, which release their products without damaging the cells.
Functional classification of exocrine glands is based on the type of secretion they produce and their mode of secretion. They can be categorized into three main types: serous glands, which secrete a watery, enzyme-rich fluid; mucous glands, which produce a thick, viscous secretion; and mixed glands, which can produce both types of secretions. Additionally, the mode of secretion can further classify them as merocrine (via exocytosis), apocrine (where part of the cell cytoplasm is lost), or holocrine (where the entire cell disintegrates).
The secretion is saliva.
The sweat gland that produces a secretion containing proteins and fats, in addition to water and salt, is the apocrine gland. These glands are primarily located in areas such as the armpits and groin and become active during puberty. The secretion from apocrine glands is thicker and can contribute to body odor when broken down by bacteria on the skin.
A cell that releases exosomes, which are small vesicles containing cell fragments and proteins, is an example of a secretion that contains cell fragments. Exosomes play roles in cell communication and the transfer of biomolecules between cells.
The sebaceous glands give off a secretion called "sebum" into the follicles.

Merocrine Glands release its product and no part of the gland is lost or damaged.

Sebaceous glands are alveolar glands, most of which open into hair follicles. Their secretion is sebum.
Pituitary gland
The two categories of glands based on their method of secretion are exocrine glands, which secrete their products into ducts that lead to the external environment or another surface, and endocrine glands, which secrete hormones directly into the bloodstream.
