Drool vs. Spit

Attribute	Drool	Spit
Definition	Saliva that drips from the mouth	Saliva that is forcibly ejected from the mouth
Volume	Usually more than spit	Usually less than drool
Causes	Often caused by excitement or hunger	Often caused by illness or disgust
Consistency	Thicker and more viscous	Thinner and more watery

Introduction

Drool and spit are two common bodily fluids that are often confused with each other. While both are produced by the salivary glands, they serve different purposes and have distinct attributes. In this article, we will explore the differences between drool and spit, examining their composition, functions, and social perceptions.

Composition

Drool, also known as saliva, is a clear and watery fluid that is produced by the salivary glands in the mouth. It contains enzymes that help break down food particles and aid in digestion. On the other hand, spit is a thicker and more viscous fluid that is produced by the salivary glands in response to stimuli such as taste or smell. While both drool and spit contain water, electrolytes, and enzymes, the composition of spit is more concentrated and may contain additional substances such as mucus.

Functions

Drool plays a crucial role in the digestive process by moistening food and initiating the breakdown of carbohydrates through the enzyme amylase. It also helps to maintain oral health by washing away bacteria and food particles that can cause tooth decay. Spit, on the other hand, serves a protective function by lubricating the mouth and throat, making it easier to swallow food and preventing dryness. Additionally, spit contains antibodies that help fight off infections and maintain the balance of oral flora.

Production

Drool is produced continuously throughout the day to keep the mouth moist and aid in digestion. The average person produces about 0.5 to 1.5 liters of drool per day, with production increasing during meals or in response to stimuli such as the sight or smell of food. Spit, on the other hand, is produced in response to specific triggers such as taste, smell, or the presence of foreign substances in the mouth. The production of spit is controlled by the autonomic nervous system and can vary depending on the individual's hydration levels and overall health.

Social Perceptions

Drool is often associated with infants and young children, who have not yet developed full control over their salivary glands. While drooling is considered normal in babies, it may be seen as a sign of immaturity or poor hygiene in adults. Spit, on the other hand, is more socially acceptable and is often used for purposes such as cleaning or lubricating objects. However, excessive spitting or spitting in public is generally frowned upon in many cultures and can be seen as disrespectful or unsanitary.

Conclusion

In conclusion, drool and spit are two distinct bodily fluids that serve different functions and have unique attributes. While drool is primarily involved in digestion and oral health, spit plays a protective role in lubricating the mouth and fighting off infections. Understanding the differences between drool and spit can help us appreciate the complexity of the human body and the importance of these often-overlooked fluids.
