No. Salt (NaCl) is a water soluble ionic compound. A glycoprotein is a molecular compound. They are two completely different classes of substances.
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.
Insulin is synthesized in significant quantities only in beta cells in the pancreas.
Endocrine glands secrete their hormones directly into the bloodstream. Exocrine glands secrete their hormones into a duct that leaves the body externally: for example, sweat glands empty onto the skin. Endocrine gland secretes compounds (hormones) into the blood. Exocrine gland secretes compounds outside of the body (including into the GI tract since the GI tract is topologically outside of the body). Exocrine glands have ducts that carry their secretory product to a surface. These glands include the sweat, sebaceous, and mammary glands and, the glands that secrete digestive enzymes.The endocrine glands do not have ducts to carry their product to a surface. They are called ductless glands. The word endocrine is derived from the Greek terms "endo," meaning within, and "krine," meaning to separate or secrete. The secretory products of endocrine glands are called hormones and are secreted directly into the blood and then carried throughout the body where they influence only those cells that have receptor sites for that hormone.
Directly into the Blood Stream. Endocrine Glands release there secretions (hormones) directly into the blood stream. That is why they are unlike Exocrine Glands.
Neurotransmitters are secreted from the axon terminals of neurons in the brain and nervous system.
Mucin
Sodium bicarbonate is secreted by the pancreas. The pancreas has both endocrine and exocrine function. Its secretion of sodium bicarbonate is part of its exocrine function.
Mucin
The mammary gland is an exocrine gland. It has ducts through which milk is secreted.
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.
Erythropoietin is secreted by the kidney to stimulate the production of red blood cells in the bone marrow.
Erythropoietin is secreted in response to hypoxia. It produces a negative feedback loop that raises the oxygen concentration of the blood. Also called EPO, erythropoietin, is a glycoprotein hormone that controls red blood cell production.
Insulin is synthesized in significant quantities only in beta cells in the pancreas.
The pancreas makes insulin and glucagon and excretes these into the bloodstream. These are hormones that help with regulation of sugar in the body. This is the endocrine part of the pancreatic function. It also makes enzymes that aid in digestion. It also makes bicarbonate to neutralize acids in the stomach. This is the exocrine part of the pancreatic function.
This depends whether the hormone is an EXOcrine hormone or an ENDOcrine hormone. EXOcrine hormones are secreted into a hollow cavity or the exterior to have a direct effect. I.e gastric hormones being secreted directly into the stomach to digest food. ENDOcrine hormone are secreted directly into the bloodstream to be carried to their target receptors and cells
There are two immunoglobulins in exocrine secretions: lgA & lgE
The proteins that are released in blood are glycoprotein and some glycoprotein may also carry blood group determinants. Human saliva contains the glycolipid mucin. Glycoprotein are important for immune cell recognition in mammals.Glycoproteins are secreted by animal cells and are used to form the ECM (extracellular matrix), which functions in support, adhesion, movement and regulation.
