"Glands without ducts" are called "ductless" or "endocrine" glands. These include the pancreas and pituitary gland. Endocrine glands produce hormones, which are then carried by the bloodstream for transport around the body. The opposite type of gland is called the exocrine glands. They include the sweat gland and the salivary gland: they have ducts, which pass hormones or other substances directly to where they are needed.
This gland would be classified as an exocrine gland. Exocrine glands secrete their products, such as enzymes or hormones, through ducts directly to the external environment or surface of the body.
Most glands do not have ducts. The ones that do are called exocrine glands; mainly these just are sweat glands, oils glands, digestive glands, and sexaul reproducitive glands.
No. Exocrine glands have tubes (ducts) leading from them to some other body part or cavity. Endocrine glands are ductless and secrete their substances.... mostly hormones..... into the intercellular space and these hormones are then picked up by the bloodstream and transported throughout the body to where they are needed.
Exocrine glands release their secretions through ducts. Examples of exocrine glands include sweat glands, salivary glands, and sebaceous glands.
Epithelial tissue is the major tissue that gives rise to glands in the body. Glands can be classified as endocrine glands (which secrete hormones directly into the bloodstream) or exocrine glands (which secrete substances through ducts to the external environment or an internal surface).
endocrine glands are glands without ducts.
Merocrine Glands
Exocrine glands have ducts. Endocrine glands do not have ducts.
Two glands that have ducts are the salivary glands and the pancreas. Salivary glands release saliva through ducts into the oral cavity to aid in digestion, while the pancreas secretes digestive enzymes and bicarbonate through ducts into the small intestine.
This gland would be classified as an exocrine gland. Exocrine glands secrete their products, such as enzymes or hormones, through ducts directly to the external environment or surface of the body.
No, sebaceous glands have ducts. They are exocrine glands.

The main difference between exocrine and endocrine glands is that endocrine glands secrete hormones into the bloodstream and have no ducts while exocrine glands secrete chemical substances into ducts.
Yes.
Exocrine glands release their secretions through ducts. Examples of exocrine glands include sweat glands, salivary glands, and sebaceous glands.
