What is lymph:

Lymph represents a colorless or slightly cloudy fluid with a composition similar to blood plasma, but with half the protein content. It originates from tissue fluid in the interstitial spaces. The movement of lymph is considerably slow and resembles the flow of blood in veins. The process of lymphatic transport is supported by the contraction of muscles in the walls of lymphatic vessels, the decrease in intrathoracic pressure during inhalation (which causes the absorption of lymph into the thoracic duct), body movement, and arterial pulsations.

Its functions:

The lymphatic system drains excess tissue fluid from the interstitial spaces back into the bloodstream. Without drainage, there would be an accumulation of fluid leading to a gradual disruption of circulation. Approximately 90% of tissue fluid is reabsorbed into the bloodstream, while about 10% is converted into lymph, which is carried away by lymphatic vessels.

The lymphatic system carries fats in the form of fat droplets from the digestive system to the superior vena cava.

The lymphatic system serves a crucial defense (immune) function. Lymphocytes accumulate in lymph nodes, where they produce antibodies. These nodes act as barriers against the spread of infections, and in case of infection, they activate defense reactions.

Manual lymphatic drainage is considered the optimal therapy for the treatment of lymphatic edema. Lymphedema is a serious condition that affects patients physically and psychologically. This condition affects the body's metabolism, including oxidative processes in cells, removal of metabolic waste products (lactic acid), and restricts the supply and movement of cellular elements (lymphocytes and macrophages), significantly impairing immunity. Removing lymphedema is crucial for strengthening the body's resistance to infections, improving mobility, and overall well-being.
