In the body, there are many types of glands and hormones. For the body to maintain homeostasis, the glands must produce certain hormones for each specific cell. Glands can be Endocrine or Exocrine and then break down into specific types. Glands release hormones for different types of cells to perform certain tasks for the body. Exocrine glands are glands that retain ducts to body surfaces. There are many activities for glands to perform. They also release enzymes, metabolites, and other molecules. Both systems may release hormones, but the Exocrine glands most likely release enzymes for the body to function. But the pancreas is the only gland that these systems share and it plays out a major role in releasing hormones to target cells.
To end, Endocrine and Exocrine glands are very different in the way they transport hormones, but they are alike in how they help the body maintain homeostasis. Hormones are the body’s chemical messengers that are sent to certain target cells. But mainly, hormones help keep the body functioning and in balance. The glands that secrete these hormones are always working and may send hormones through ducts, if it’s an exocrine gland, or directly through the bloodstream if it’s endocrine. The pancreas creates the Insulin hormone which maintain blood sugar levels and help properly digest the food a human consumes. Like all glands, each one produces a hormone that is for a direct cell to respond to.
Hormones are your body's chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including
Growth and development
Metabolism - how your body gets energy from the foods you eat
Endocrine glands, which are special groups of cells, make hormones. The major endocrine glands are the pituitary, pineal, thymus, thyroid, adrenal glands and pancreas. In addition, men produce hormones in their testes and women produce them in their ovaries. The ovary hormone Estrogens, works to create growth promotion, maintain elasticity of connective tissues, preserve bone mass and, and vascular compliance. For the male testes, the hormone testosterone, creates growth of male secondary sexual characteristics, sperm production and libido. It i
The hormone that works for the pancreas, is called Insulin and it helps the pancreas achieve to regulate blood sugar levels. Most hormones are Steroid Hormones synthesized from cholesterol, or Protein hormones, which are synthesized by amino acids. But in order for a hormone to reach its target, it must received by the binging site of receptor molecules which are either proteins, or Glycoproteins. The Pituitary gland secretes the Luteinizing hormone, which In females this LH acts on the ovary to stimulate the production of estrogens and induce ovulation. In males this LH acts on the testis to stimulate the production of testosterone.
To start, the Endocrine and Exocrine glands produce hormones for their main priority, to reach cells. Endocrine glands like the Thyroid can be large and obvious, but others are small with very little duties to fulfill. Exocrine glands are buried further into tissues, but when they act out their job, there are ducts to connect them to the surface. There are different types of Exocrine that are simple, which are tubular, branch tubular, coiled tubular, and branched alveolar. But more advanced types are the Alveolar.

Exocrine glands manufacture and release hormones. These hormones are transported to the surround area, and to the blood. A specific receptor is then needed for that hormone to do its specified job. The ducts may be simple or compound. Simple ducts are ducts that are single, while compound ducts accommodate more areas, because they branch out. These ducts can coil and turn in different ways giving rise to sub-classifications, depending on the shape of the ducts. Classifications of exocrine ducts are merocrine glands, holocrine glands and apocrine glands. Secretions in merocrine glands are generated by intact cells. In holocrine glands, cells are permitted to break up to produce compounds, and discharge desired secretions. Apocrine glands dispense the cells with their secretion. Cells are sprouting, and are replaced when needed. These glands secrete proteins or mucus depending on where they are located.
Materials and Methods
For the completion of this project, the class had to use computers to research topics on glands and hormones. We had to research the Exocrine and Endocrine glands to discover how they secrete their hormones for the body.
All of our thanks in this project should be projected to our biology teacher. The education in this project has been absorbed very well thanks to our families because their support is more thank we could ask for.
