What happens in my body when I vomit?

Salivary glands, the unsung heroes of our oral health, play a vital role in the digestive process and in maintaining oral hygiene. These glands, typically situated in and around the mouth, produce saliva, a clear liquid essential for several functions.

Firstly, saliva aids in digestion. It contains enzymes, such as amylase, which kickstart the breakdown of carbohydrates in food, facilitating the digestive process even before food reaches the stomach. This pre-digestion action helps ease the workload on the stomach and small intestine, promoting efficient nutrient absorption.

Saliva also lubricates the mouth, making it easier to speak, chew, and swallow. Without sufficient saliva, these basic functions become challenging, leading to discomfort and potentially affecting overall health.

Moreover, saliva serves as a natural cleanser for the mouth. It washes away food particles, bacteria, and debris, helping to prevent tooth decay, gum disease, and bad breath. Saliva's antimicrobial properties inhibit bacterial growth, contributing to oral hygiene.

Interestingly, saliva contains substances that promote wound healing and protect oral tissues. Growth factors present in saliva aid in tissue repair, while proteins like histatins have antimicrobial properties, further safeguarding against infections.

Additionally, saliva plays a crucial role in taste perception. Saliva carries taste molecules to taste receptors on the tongue, enhancing our ability to perceive flavors and enjoy food.

The production of saliva is regulated by the autonomic nervous system, with both parasympathetic and sympathetic pathways influencing its secretion. Factors such as sight, smell, and even the thought of food can trigger salivary gland activity.

However, salivary gland dysfunction can occur due to various factors, including medications, dehydration, autoimmune diseases, and radiation therapy. Reduced saliva production, known as dry mouth or xerostomia, can lead to oral discomfort, difficulty swallowing, and an increased risk of dental problems.

In conclusion, salivary glands play a multifaceted role in maintaining oral health and promoting efficient digestion. Their secretion of saliva not only aids in digestion and lubrication but also cleanses the mouth, protects oral tissues, enhances taste perception, and contributes to overall oral hygiene and well-being.
