The salivary glands in mammals are exocrine glands, glands with ducts, that produce saliva. They also secrete amylase, an enzyme that breaks down starch into maltose.
The salivary glands are detailed below:
The two parotid glands are major salivary glands wrapped around the mandibular ramus in humans. The largest of the salivary glands, they secrete saliva to facilitate mastication and swallowing and to begin the digestion of starches. It is the serous type of gland which secretes the ptyalin. It enters the oral cavity via the parotid duct or Stensen duct. The glands are located posterior to the mandibular ramus and anterior to the mastoid process of temporal bone. They are clinically relevant in dissections of facial nerve branches while exposing the different lobes of it since any iatrogenic lesion will result in either loss of action or strength of muscles involved in facial expression. They produce 20% of the total salivary content in the oral cavity.
The human body is the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. Every part of the body is composed of various types of cells, the fundamental unit of life.
At maturity, the estimated average number of cells in the body is given as 37.2 trillion. This number is stated to be of partial data and to be used as a starting point for further calculations. The number given is arrived at by totalling the cell numbers of all the organs of the body and cell types. The composition of the human body is made up of a number of certain elements including carbon, calcium and phosphorus.
The study of the human body involves anatomy and physiology. The human body can show anatomical non-pathological anomalies known as variations which need to be able to be recognised. Physiology focuses on the systems and their organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis.

This is a video of me removing a salivary gland stone, or a sialolith, from my submandibular salivary gland (right under your tongue). It's not like I decided to do this in the beginning, it just kind of happened that way. I went to an Urgent Care clinic in the morning since the pain was so bad and before I could get into and EENT doctor in the afternoon the pressure was causing things to happen on their own without much help. As I watched it unfold I thought, "might as well get some cool video and just finish what's going to happen anyways."
Sialolithiasis (also termed salivary calculi, or salivary stones), is a condition where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed "Wharton's duct"). Less commonly the parotid gland or rarely the sublingual gland or a minor salivary gland may develop salivary stones. The usual symptoms are pain and swelling of the affected salivary gland, both of which get worse when salivary flow is stimulated, e.g. with the sight, thought, smell or taste of food, or with hunger or chewing. This is often termed "mealtime syndrome".Inflammation or infection of the gland may develop as a result. Sialolithiasis may also develop because of the presence of existing chronic infection of the glands, dehydration (e.g. use of phenothiaz...

This pyramidal-shaped gland secretes purely serous saliva and its contribution makes up approximately thirty percent of the total saliva output.

This video demonstrates some huge salivary gland stones and an infected blocked duct.
Human digestive system contains various glands, including salivary glands in mouth, gastric glands of stomach, intestinal glands etc., which are explained in this animation alongwith their functions.
Sorry for the late video, after this video I was bedridden with what seems to of been the flu. Finally, feeling better and will be doing another video soon. I have had problems with my Parotid salivary glands for many years. I also recently got diagnosed with secondary Sjogrens. Let me know in the comments below if you've had a similar issue. I know I have many viewers with Sjogrens as well! Hope to hear from you all. https://www.livehopelupus.org https://instagram.com/samanthamwayne
