The ones I know about are:
1. Pineal Gland also known as Pineal Body or Epiphysis Celebri
2. Pituitary Gland
Pitutary gland and pineal gland.
The chemical messages are called as hormones. They are released by the ductless endocrine glands into the bloodstream.
An endocrine gland is a ductless gland that produces and secretes hormones into the blood or lymph nodes, affecting specific target tissues throughout the body. Endocrine glands include the pituitary, pineal, hypothalamus, thymus, thyroid, parathyroid, adrenal cortex, adrenal medulla, islets of Langerhans and gonads ie testes and ovaries.
Liver, salivary gland, pyloric stomach, pancreas, duodenum of small intestines
The endocrine system is a collection of glands that secrete chemical messages called hormones. The endocrine system consists of the pancreas, thyroid, parathyroid, adrenals, pineal, pituitary and testes/ovaries.
The Endocrine System means the structure of glands that secrete hormones through the circulatory system into the receptive organs. The main Endocrine glands include; the Adrenal glands, Gastrointestinal tract, the Hypothalamus, the Ovaries, the Pineal gland, the Pituitary gland, the Pancreas, the Parathyroid gland, the Testes and the Thyroid gland. There are other organs in the body, such as the Gonads, Heart, Kidney and Liver which have secondary endocrine functions. The gonads secrete Androgens and Estrogens. The heart secretes Peptins. The kidney secretes Erythropoietin and Renin. The liver secretes Angiotensin and Somatomedin. They all work together as a system that keeps the internal structure healthy. This is not a full list of the structure.
Errrr, you didn't really give other organ systems so I'll just list a few. The Endocrine system (Glands) The Circulatory system (Heart, Veins, Arteries) The Respitory System (Lungs, Bronchial tubes) Nervous system (Brain, Spinal Column, Nerves) The Digestive system (Stomach, Gallblader, Intestines) The Skeletal System (Bones) The Muscular System (Muscles) Hope that answered your question
DefinitionEndocrine glands release hormones into the bloodstream.Endocrine glands include the:AdrenalHypothalamusIslets of Langerhans in the pancreasOvariesParathyroidPinealPituitaryTestesThyroidInformationWhen a gland releases a substance, it is called secretion. Hypersecretion is when too many hormones are released. Hyposecretion is when too few hormones are released.Many different disorders can result when too few hormones or too many hormones are released.Here is a partial list of disorders that may result when a particular gland does not produce the right amount of hormones.Adrenal:Addison's diseaseAdrenogenital syndromeCushing syndromePheochromocytomaPancreas:DiabetesHypoglycemiaParathyroid:TetanyRenal calculiExcessive loss of minerals from bonePituitary:Growth hormone deficiencyAcromegalyDiabetesGigantismDiabetes insipidusTestes and ovaries:Lack of sex development (unclear genitalia)Thyroid:Congenital hypothyroidismMyxedemaGoiterThyrotoxicosisReferencesGill GN, Clemmons DR.

The major physical concerns of smoking is a long list. Smoking hurts everything from the organs, the skin, the teeth, the respiratory system, the endocrine system, the brain, the excretory system, and more. It's infinitely better to not smoke instead.
Just ductless glands of which there is a list

Flat cells, cuboid cells and columnar cells. Flat cells are there in skin. Cuboid cells in the acinus of thyroid gland. Columner cells are present in intestinal glands, where more secretions are needed.
