Endocrine glands secrete their products into the blood whereas the Exocrine glands secrete their products directly into the target organ for example the parotid gland secretes the salyva directly into the mouth without using theblood for transpor.
The nervous system responds to short term stress by releasing adrenaline and noradrenaline. The release of these hormones increase blood pressure, heart rate, and they divert blood to all the needed organs and muscles. The endocrine system helps us deal with short term stress by releasing a series of hormones to help bring the body to homeostasis.
Paracrines are a group of local hormones that work on nearby cells. Autocrines stimulate the same cell and circulating hormones can travel long distances to stimulate cells. Hormones only stimulate cells that have their specific receptor.
Nerve impulses and hormones (apex)
Your nervous system helps maintain balance in the body's processes by interpreting information about the environment and then telling parts of the body to act. Your endocrine system also helps balance your body's processes. But it controls slower processes, such as growth and sugar levels in the blood.
steroid hormones can pass easily through the plasma membrane, the hormones then bind to intracellular receptors which induce a metabolic pathway which later promotes transcription of a specific gene.
I think the student wanted to ask about the difference between an exocrine and endocrine gland but mistakened and wrote both the same. Exocrine gland differ from Endocrine gland because in case of exocrine glands ezymes are secreted by ducts carrying them to their site of actions but in case of endocrine hormones are secreted in body without ducts and are cariied by circulatory fluid of the organism.
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
act locally instead of at a distance
Speed and duration. Nerves are faster, hormones last longer.
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.

Endocrine glands: - are ductless ("endo" means "internal") and supply their products directly into the bloodstream, - manufacture hormones (biological chemicals that influence the operation of other organs and tissues), - include the pituitary gland, pancreas, ovaries, testes, thyroid gland, and adrenal glands. The stomach also has endocrine activity, - are critical to bodily functions. The thyroid creates thyroxin, which regulates the body's overall metabolic rate. Low thyroxin (hypothyroidism) means low energy consumption, lethargy and weight gain, for example. A faulty pancreas leads to low insulin levels, excessive/erratic blood sugar, and diabetes, - differ from exocrine ("external") glands such as the liver, which supplies products into other body systems, such as bile into the digestive tract. ENDOCRINE GLANDS ARE DUCTLESS
the endocrine system: controls growth, development and metabolism maintains homeostasis sends messages through the body
The nervous system responds to short term stress by releasing adrenaline and noradrenaline. The release of these hormones increase blood pressure, heart rate, and they divert blood to all the needed organs and muscles. The endocrine system helps us deal with short term stress by releasing a series of hormones to help bring the body to homeostasis.
secretion adds material to the filtrate; reabsorption removes materials from the filtrate
Endocrine glands secrete into the bloodstream. in contrast, other glands secrete their products via ducts.
They produce chemical messagers that travel trough the blood, sometimes at quite a distance.
