DNL Canada Heart and Circulatory Natural Supplements

The circulatory system, also called the cardiovascular system permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from cells in the body to nourish it and help to fight diseases, stabilize body temperature and pH, and to maintain homeostasis.

 

The circulatory system is often seen to comprise both the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph.  The passage of lymph for example takes a lot longer than that of blood.  Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. Lymph is essentially recycled excess blood plasma after it has been filtered from the interstitial fluid (between cells) and returned to the lymphatic system. The cardiovascular system comprises the blood, heart, and blood vessels.   The lymph, lymph nodes, and lymph vessels form the lymphatic system, which returns filtered blood plasma from the interstitial fluid (between cells) as lymph.

 

Humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries). The lymphatic system is an open system providing an accessory route for excess interstitial fluid to get returned to the blood.
