Cirulatory System

The role of the circulatory system is twofold: it delivers oxygen and nutrients to all parts of the body while picking up waste and toxic materials that need to be eliminated. It accomplishes this monumental task through a network of nearly 60,000 miles of blood vessels and a fist sized organ, the heart, which pumps more than 2,000 gallons of blood through its chambers each day.

The body has of blood continually traveling through it in a “loop” formed by the heart, lungs blood vessels. The circulatory system delivers oxygen and nutrients to the body and picks up waste and toxins that need to be eliminated. This system has three phases.

The first phase is pulmonary circulation is the movement of blood from the heart, to the lungs and back to the heart again. Waste-rich blood is pumped through the heart to the lungs, where the exchange of carbon dioxide and oxygen happens. Following this exchange the pumping action of the heart forces the fresh oxygen rich blood back out on its journey through the body.

The second phase is coronary circulation is the movement of blood through the tissues of the heart itself. This circulation provides the hard-working heart organ with the oxygen and nutrients that it needs to survive.

The third phase is systemic circulation supplies nourishment to all of the body’s tissues. Oxygen-rich blood enters the capillaries where oxygen and nutrients are released and waste products are collected. The waste rich blood then flows into the veins to be circulated back to the heart where pulmonary circulation begins again.

Transporting your life blood

Blood vessels are divided into three main categories: arteries, veins and capillaries. Arteries are thick walled vessels that carry blood from the heart to all parts of the body. Each time a person’s heart beats, the elastic walls of the arteries swell to make room for the blood that is forced into them. The muscles inside the walls contract slowly in effect squeezing the blood and forcing it to move along the arteries toward the capillaries. If arteries lose their elasticity known as hardening of the arteries, the heart has to work much harder to keep the blood circulating. If the heart is overworked and not properly maintained it cannot function optimally.

 The Lymphatic System

In addition to moving the blood along, the squeezing process forces fat globules, tiny protein particles and other nutrients to go outside of vessel walls. Once these things are out, due to their size, they cannot reenter. Instead, they are collected along with other cellular debris lying between cells.

The lymphatic system picks up these particles and mixes them with plasma which forms lymph. The lymph is then purified, recycled in the lymph nodes and added back to the blood. This process is vital to the circulatory system and is essential to the success of the immune system.

 The return trip

Veins are thin walled blood vessels. Their purpose is to return the blood from the body to the heart. Many larger veins have valves to prevent a back-flow of blood. If these valves experience prolonged or excessive pressure, veins can become overstretched and the valves may be destroyed or rendered incompetent.

Capillaries are the smallest blood vessels in the body. They serve as intermediaries, connecting arteries with veins. Since capillaries are extremely small and have permeable walls, it’s possible for capillaries to reach nearly every cell in the body and to transfer substances, including important nutrients to and from the tissues.

 The Heart

 The heart is made up primarily of muscles that facilitate its pumping action. This most vital of organs consists of four compartments or chambers. The upper two are referred to as the atria and the lower two as ventricles. Oxygen poor blood enters the right atrium and moves through it to the right ventricle. From there, blood is sent via the pulmonary arteries to the lungs so that it can pick up a fresh supply of oxygen. Once it has taken on a supply of oxygen, blood moves through the pulmonary veins first to the left atrium and then to the left ventricle.

The heartbeat is sustained by the sinoatrial (SA) node which functions as a pacemaker. A healthy heart has a regular beat, although the rate can vary depending on several factors including age, sex, physical activity and emotion.

 Health factors

For the circulatory system to function properly the heart must be strong, the vessels capable of safely transporting optimal amounts of blood and the blood itself must be healthy. Serious problems can arise when these conditions are not met. Each year approximately 25 percent of all deaths in the U.S. occur from heart attacks and the majority of these are from less than optimal blood flow. A poor circulatory system can lead to a variety of other conditions that can kill or severely limit the enjoyment of life.

Three major factors that contribute to circulatory problems are to maintain blood pressure already in the normal range, maintain cholesterol levels already in the normal range and smoking. Other factors include obesity, heredity and emotional stress. The threat of problems increases significantly when more than one factor is present. That means that when a person has three risk factors his chances for disease are six times greater than when only one is present.

How can you maintain a healthy circulatory system? Most experts agree that the keys are to avoid smoking, monitor your diet, exercise regularly and manage stress.

NSP offers several key products to help this intricate system stay balanced.

 Super Omega-3 EPA®

Research shows that consuming omega-3 fatty acids, such as EPA and DHA found in fish oil may help reduce the risk of heart disease. Each Super Omega-3 softgel contains 380 mg EPA and 190 mg DHA, plus natural lemon oil to minimize the aftertaste of fish. Omega-3 fatty acids may help maintain blood pressure levels already within the normal range as well as benefit the structural system and the skin.


Mega-Chel provides the body with a powerhouse of nutritional support for the circulatory system, including generous amounts of needed vitamins, essential minerals, amino acids, glandular substances and herbs known to support healthy circulation. Mega-Chel contains CoQ-10, ginkgo, hawthorn and other nutrients that work together to help promote optimal blood flow.
