Glandular structure is a type of tissue that performs a specific function, usually by secreting substances. Epithelial tissues make up the lining of the glands. With their different secretions, they can control the different processes that occur in the body, especially those that are of endocrine in origin or excrete unwanted waste products.
The widely-distributed glandular structure comes from the exocrine gland. The glands pour their secretion through a tube. You can find them in the skin, pancreas, mammary glands, and salivary glands. Their name and the function of their secretion depend on their location. If it is the pancreas, the secretions are called the pancreatic juices and they work in digesting the food molecules. If from the skin, the sweat contains the excess electrolytes and water; and, lastly, if it comes from the breasts, you call it milk. The stimulus for their secretion depends on the internal or external stimuli.
The glandular structure of the endocrine system secretes a chemical substance called the hormones. The hormones are the next controlling substances in the body next to the nervous system. Unlike the exocrine glandular structure, the endocrine pours the secretion directly to the blood stream. They are the ductless glands that affect the body at large. Some of the important organs are the pituitary, thyroid, parathyroid, hypothalamus, ovaries, testes, pancreas, and thymus. All these organs have their specific target organs.
Overgrowth of cells can also occur in the glandular structure. If it happens, it can lead to cancer cell formation. If the involved organs are the endocrine glands, the hormones produced can reach a too-high level, which can be life threatening. In this case, your doctor will prescribe you with some medications to control its metastasis.
Glandular structure is one of the important parts of the body. Its specific structure allows it to perform a wide variety of functions.
