How do endocrine glands differ from other glands?

Answer 1

Endocrine glands secrete hormones and exocrine glands secrete enzymes. Endocrine glands secrete hormones directly into the blood stream, while exocrine glands secrete enzymes through ducts. endocrine is ductless gland exocrine retain their duct, exocrine empty through their duct to epithelial such as sweat, oil, glands, liver and pancrease

Answer 2

Exocrine pancreas is related to secretion of digestive enzymes that are secreted from secretory acini and transported to GIT through duct system. Main duct of this system is the pancreatic duct. While the endocrine pancreas is concerned with secretion of metabollic hormones- insuline and glucagon and small quantity of somatostatin, it has no duct system and secretions are poured directly into blood.

Answer 3

The glands in human body are of two types. One is exocrine glands and the other isendocrine glands. The exocrine glands produce fluid secretions that are delivered by tubes or ducts either to the body surface for example glands of skin or to the inner regions where these are required for example pancreas delivers its pancreatic juice to the intestine for digesting food etc. Endocrine glands produce secretions called hormones that are not carried by ducts but are passed into the blood streamand carried to the target area by blood circulation. The following endocrine glands are present in human body; pituitary gland, pancreas (islets of langerhans), thyroid gland, adrenal glands, and gonads. The function of endocrine glands is very much inter-related. Several of the hormones produced by them serve only to alter the functions of other endocrine glands. They serve as double check automatic control over one another. The pituitary gland is known as master gland in the body and plays an important role in several ways. It has certain hormones which have direct action on the body for example the growth hormone. Thyroid gland is located in the neck and fits closely around the from and side of trachea just below the organ of voice of larynx.

Endocrine glands lose their connection to the surface, and are often called ductless glands. Their secretions diffuse directly into the blood vessels that weave through the glands. Exocrine glands retain their ducts and their secretions empty through the ducts to the epithelieal surface. They are both internal and external.

The function of the endocrine system is to secrete regulatory hormones into the bloodstream, whereas the exocrine system is designed to secrete substances other than hormones, into ducts which lead to the external environment. To compare structure, endocrine glands are far more vascular, and do not require ducts.

Endocrine glands include such organs as the pituitary and adrenal glands. Exocrine glands include such things as sweat, salivary and mammary glands.

Not all glands are exclusively endocrine or exocrine; the pancreas produces both insulin which is released into the bloodstream, and pancreatic juices which are directed into the digestive tract via the pancreatic duct.
Endocrine Glands eventually lose their ducts, they are often call doctles glands; they produce hormones.

Exocrine Glands secrete their products into body surfaces (skin) or body cavities, they include mucous, sweat, osl, and salivary glands.

Unicellular exocrine glands produ mucin a glyro protain that dissolve in water when secreted, once disolve musin forms mucus. In globe cells mucin distine the top of the cell, making the cell look like a glass with a steam.

Answer 4

endocrine glands are ductless while exocrine glands have ducts.

endocrine glands secrete hormonal substances such as estrogen and testosterone while exocrine glands excrete non-hormonal substances such as sweat, tears, saliva and oil.

Answer 5

Endocrine glands are ductless while exocrine glands have ducts.

Endocrine glands secrete while exocrine glands excrete.

Endocrine glands produce hormonal substances while exocrine glands produce non-hormonal substances such as sweat, tears, and oil.

Answer 6

The endocrine and exocrine systems act with nervous system to coordinate the body's activities.

Answer 7

Endocrine glands secrete hormones directly into the bloodstream. In contrast, exocrine glands secrete via ducts.
