The lymphatic system is the secondary transport system
The other branch of the body�s transportation system is the lymphatic system, which is the secondary transport system.
The force of blood pressure as the blood moves through the arteries squeezes out some fat globules, tiny protein particles, and other nutrients. Because of their size, they are too big to squeeze back in. Cell debris also collects between the cells. This is where the lymphatic system comes into play.
It picks up these particles and mixes them with plasma, forming lymph. The valuable contents of lymph are purified, recycled in the lymph nodes and added back to the blood.
In addition, the lymphatic system is vitally important to the success of the immune system.
Like the transportation system of a city, our body�s transportation system must be properly cared for so it will not become clogged or restricted in its natural flow.
In today�s high-tech, high-stress world, there is a real concern about cardiovascular problems. In fact, each year more than 1 million Americans suffer from heart attacks; about 350,000 survive.
The three big factors contributing to circulatory problems are hypertension (high blood pressure), high levels of triglycerides and cholesterol in the bloodstream, and smoking. Other factors include obesity, heredity and emotional stress.
One risk factor may lead to another, and there is increased risk of circulatory problems when more than one risk factor is present. For example, when a person has three risk factors, the chances of disease are six times greater than if only one were present.
Maintaining a healthy circulatory system requires pure water, regular physical exercise, stress management and, of course, good nutrition.
