salivary gland

Examples of salivary gland in the following topics:

• The Golgi Apparatus

  • In another example of form following function, cells that engage in a great deal of secretory activity (such as cells of the salivary glands that secrete digestive enzymes or cells of the immune system that secrete antibodies) have an abundance of Golgi.

• Digestive System: Mouth and Stomach

  • As food is chewed, saliva, produced by the salivary glands, mixes with the food.
  • There are three major glands that secrete saliva: the parotid, the submandibular, and the sublingual.
  • In addition, saliva contains an enzyme called salivary amylase that begins the process of converting starches in the food into a disaccharide called maltose.
  • Food is masticated by teeth and moistened by saliva secreted from the (b) salivary glands.

• Neural Responses to Food

  • The salivary glands secrete more saliva in response to the stimulus presented by food in preparation for digestion.
  • The gastric and salivary secretion in the cephalic phase can also take place at the thought of food.

• Phylum Rotifera

  • Food passes by digestive and salivary glands into the stomach and then into the intestines.

• Digestive Systems

  • These include the salivary glands, the liver, and the pancreas.

• Excavata

  • The parasite then travels to the insect salivary glands to be transmitted to another human or other mammal when the infected tsetse fly consumes another blood meal.

• Digestive System: Small and Large Intestines

  • Digestive juices from the pancreas, liver, and gallbladder, as well as from gland cells of the intestinal wall itself, enter the duodenum.
  • Accessory organs include salivary glands, the liver, the pancreas, and the gallbladder.
  • The pancreas is another important gland that secretes digestive juices.

• Digestion and Absorption

  • Digestive enzymes are diverse and are found in the saliva secreted by the salivary glands, in the stomach secreted by cells lining the stomach, in the pancreatic juice secreted by pancreatic exocrine cells, and in the intestinal (small and large) secretions, or as part of the lining of the gastrointestinal tract.
  • The salivary enzyme amylase begins the breakdown of food starches into maltose, a disaccharide.

• Thyroid Gland

  • The thyroid gland, the largest endocrine gland, is responsible for the production of the hormones T3, T4, and calcitonin.
  • The thyroid gland, one of the largest endocrine glands in the body, is located in the neck, just below the larynx and in front of the trachea .
  • It is a butterfly-shaped gland with two lobes that are connected by the isthmus.
  • The thyroid gland produces the hormones T3 (triiodothyronine) and T4 (thyroxine).
  • The location of the thyroid gland is in the neck below the larynx and in front of the trachea; it is the largest endocrine gland in the body, producing T3, T4, and calcitonin.

• Parathyroid Glands

  • The parathyroid glands are small endocrine glands that produce parathyroid hormone.
  • These glands are located on the posterior surface of the thyroid gland.
  • Normally, there is a superior gland and an inferior gland associated with each of the thyroid's two lobes .
  • The parathyroid glands are located on the posterior of the thyroid gland.
  • Describe how the parathyroid glands regulate calcium levels in the blood
