Sometimes you can tell that something is off with your health. You don’t feel your normal self, you’re exhausted and feeling flat.

Something in your body isn’t in optimal condition and so begins the journey to diagnose and heal it.

The eleven systems of the human body are complex and fascinating. They work in harmony with each other to allow our bodies to function. What is the role of the lymphatic system in your body?

Here’s a simple guide to this important bodily system and how it contributes to your overall health.

What Is the Role of the Lymphatic System?

The lymphatic system has two main functions:

  1. To defend the body from foreign organisms like bacteria and viruses
  2. To move interstitial fluid and other substances from the digestive system into the bloodstream through the lymphatic drainage system

What Is Interstitial Fluid?

Interstitial fluid is the fluid that surrounds the cells in the body. It constitutes about 40% of our body’s water, adding up to a sixth of our body weight.

Its role in the lymphatic system is to help transport lymph fluid around the body so that it can clear out foreign organisms from the organs and tissues of the body.

What Is Lymph Fluid?

Lymph is a clear fluid that carries lymphocytes, proteins, and fats that work to fight bacteria and provide nutrients to the cells in the body.

How Does the Lymphatic System Work?

The lymphatic system is a part of the immune system. It is made up of organs, tissues, and vessels in the body that work together to transport lymph fluid around the body and back into the bloodstream. 

Every day, the body moves close to twenty liters of plasma (another type of extracellular fluid in the body) around the body. Plasma delivers nutrients to the cells of the body, collects its waste, and then returns roughly seventeen liters of this plasma is returned to circulation.

The 3 liters that don’t return to circulation become lymph fluid after they seep into the body’s tissues. The lymphatic system then moves this lymph fluid around the body until it returns it back to circulation.

Other Functions of the Lymphatic System

The lymphatic system has a number of roles in the body:

  1. Maintains protein and fluid balance in the body
  2. Absorbs fats and carbohydrates from the gastrointestinal tract to aid metabolism
  3. Produces lymphocytes that rid the body of foreign invaders

Signs of Lymphatic Dysfunction

Because the lymphatic system works to keep fluids circulating around the body a sign of lymphatic dysfunction is swelling in the arms and legs or any other part of the body. This is known as lymphedema.

Lymphedema can also cause skin changes, infection, blisters, and difficulty breathing and swallowing.

How to Maintain a Healthy Lymphatic System

The best way to keep your lymph system healthy is to maintain a healthy lifestyle with regular exercise and avoiding toxins in your environment as much as possible. Drink plenty of water to aid the body in circulating fluids.
