Endocrine Systems What is the difference between the endocrine gland and the exocrine gland? Endocrine gland is a gland whose secretions (called hormones) are collected by the blood and reach the tissues through the circulation. The hypophysis (pituitary) and the adrenals are examples of endocrine glands. Exocrine gland is a gland whose secretions are released externally through ducts (into the skin, intestinal lumen, mouth, etc.). The sebaceous glands and the salivary glands are examples of exocrine glands.

RIXIMKA DUMARKA Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct.The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.The hypothalamus and pituitary gland are neuroendocrine organs.he pancreas, located in the abdomen close to the stomach, is both an exocrine and an endocrine gland. The endocrine portion (islets of langerhans) releases insulin and glucagon and smaller amounts of other hormones to the blood.

What is the Endocrine System? The endocrine system is a collection of glands and organs that produce and regulate hormones in the bloodstream to control many functions of the body. This system overlaps with the nervous system and exocrine system, and its responsibilities include metabolism, growth and sexual development.

- Answer by MelindaS (1694) Actually, a gland is a more specific name for an organ. An organ is any specialized group of cells that together perform a certain function. A gland is a type of organ that produces a hormone. An example of a gland would be your thyroid, pituitary, or your pancreas. They produce different hormones.

- A hormone (from Greek ὁρμή, impetus) is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.ormone cells are typically of a specialized cell type, residing within a particular endocrine gland, such as the thyroid gland, ovaries, and testes. Hormones exit their cell of origin via exocytosis or another means of membrane transport.

What are some examples of endocrine glands? Simply put, the endocrine system is a network of glands that secrete chemicals called hormones to help your body function properly. Hormones are chemical signals that coordinate a range of bodily functions. The endocrine system works to regulate certain internal processes.he Endocrine System Essentials. 1  The endocrine system is made up of a network of glands. 2  These glands secrete hormones to regulate many bodily functions, including growth and metabolism.

- The thymus gland is an organ in the upper chest cavity that processes lymphocytes, a type of white blood cell that fights infections in the body. This organ is part of both the lymphatic system, which makes up a major part of the immune system, and the endocrine system, which includes all glands that produce hormones.he thymus gland is most important to children and young adults as it programs white blood cells to attack antigens. Different types of white blood cells programmed within the thymus gland.

Human Physiology/The endocrine system A hormone is a chemical messenger produced by a cell that effects specific change in the cellular activity of other cells (target cells). Unlike exocrine glands (which produce substances such as saliva, milk, stomach acid and digestive enzymes), endocrine glands do not secrete substances into ducts (tubes).

- The liver is considered a gland—an organ that secretes chemicals—because it produces bile, a substance needed to digest fats. Bile’s salts break up fat into smaller pieces so it can be absorbed more easily in the small intestine.
