In this continued exploration of the key components and functions of the lymphatic system we delve into the anatomy, physiology and indispensable roles, that make it an indispensable player, in maintaining the body’s equilibrium and safeguarding against infections and diseases.

This lymphatic system works in tandem with the cardiovascular system to circulate lymph throughout the body. The lymphatic system is a crucial, yet often overlooked component of the human body, that plays a fundamental role in maintaining fluid balance, immune function and overall health.

Key components of the Lymphatic System
Lymph Nodes:

Small, bean shaped structures scattered throughout the body. They act as filters, trapping and removing harmful substances, such as bacteria and viruses, from the lymph before it returns to the bloodstream.
Lymph Vessels:
Lymphatic vessels form an extensive network that parallels the blood vessels. These vessels transport lymph, which contains white blood cells, proteins, excess fluid, cellular debris and pathogens, away from the tissues and towards the lymph nodes.
The spleen is an organ located below the ribcage on the left side of the body. It plays a vital role in filtering blood and removing damaged blood cells. Additionally, the spleen stores platelets and white blood cells.
The thymus is a small organ situated in the chest behind the breastbone. It is crucial for the development and maturation of T lymphocytes, a type of white blood cell that plays a central role in the immune system. T cells are the cells that identify and attack cancer cells in the body.

Functions of the Lymphatic System
Immune Response:

A primary function of the lymphatic system is to support the immune system. Lymph nodes are checkpoints where immune cells encounter and combat foreign invaders, such as bacteria, viruses and abnormal cells.

Fluid Balance:
The lymphatic system helps maintain fluid balance in the body by collecting excess fluid from the tissues and returning it to the bloodstream preventing the accumulation of fluid that can lead to edema or swelling.
Nutrient Absorption:
Lymphatic vessels located in the digestive system, known as lacteals, aid in the absorption of dietary fats and fat-soluble vitamins. These nutrients are transported in the form of chyle, a milky fluid, to the bloodstream.
Lymph nodes filter and detoxify the lymph on its way to the bloodstream by removing toxins and waste products from cellular metabolism. This is essential for maintaining a healthy and functioning immune system.

The cardiovascular and respiratory systems often take center stage while the lymphatic system quietly performs its duties, safe guarding our health and well-being. From immune defense to fluid balance and nutrient absorption, the lymphatic system is an unsung hero that deserves our appreciation and attention! Understanding its function sheds light on our body’s abilities to defend itself and remain healthy and prevent progression or improve symptoms of disorder and
disease. Understanding its function recognizes and supports all systems working in harmony.

So let’s celebrate the marvels of the lymphatic system and love your lymphatics!

Love your Lymphatics!

Upwards of 80% of North Americans suffer from some degree of cortisol imbalance, otherwise known as adrenal fatigue.

Our adrenal glands are pyramid-shaped glands that sit on top of each kidney, and are responsible for producing multiple hormones. Included in this list of important hormones are progesterone, testosterone, estrogen and cortisol. The role of cortisol is to help us manage all types of stress – emotional, physical (inflammation) and
