The exocrine gland that secretes products with no loss of cellular material is called a merocrine gland.

Here's why:

* Merocrine glands release their secretions through exocytosis, a process where the secretory product is packaged into vesicles and transported to the cell membrane. The vesicles fuse with the membrane and release the product outside the cell. The cell itself remains intact and undamaged.

Let's contrast this with other types of exocrine glands:

* Apocrine glands release their secretions by pinching off a portion of the cell's cytoplasm. This involves some loss of cellular material.

* Holocrine glands release their secretions by the entire cell breaking down and releasing its contents. This is a complete loss of cellular material.

Examples of merocrine glands include:

* Sweat glands (producing watery sweat)

* Salivary glands (producing saliva)

* Pancreas (producing digestive enzymes)
