The term cardiovascular refers to the heart (cardio) and the blood vessels (vascular). The cardiovascular system includes the heart, arteries, veins, arterioles, venules, and capillaries.
I would say that the heart and the blood vessels are the main components of the cirulatory system. This means that the Heart and blood vessels have the task of delivering blood to the organism cells.
But a third component that is vital to complete the cardiovascular system is the respiratory system. It doesn't pump the blood, but the cardiovascular system wouldn't be complete without this third component, because the oxygen would not be delivered to the cells. However, the response to your question is contained in the first paragraph, in bold.
The organs of the circulatory system include the blood, blood vessels, and heart. The blood is an unusual organ in that it is a liquid.
The heart and the blood vessels
The heart and the blood vessels.
Two many functions of the circulatory system are the movement of nutrients and oxygen to the tissues, and movement of wastes from the tissues to the excretory system. The main organs are the heart and blood vessels.
The skin is an organ by itself, but the circulatory system and nervous system both have direct connections with the skin (through capillaries in the case of circulatory and nerve endings in the case of nervous system.)
The two external controls of the circulatory system is the house.
heart and blood vessels
The two main part of circulatory system are hearth and Arteries
The circulatory system works with the respiratory system to oxygenate the body. The respiratory system brings oxygen into the body through the lungs, where it is then picked up by red blood cells in the circulatory system and transported to tissues and organs.
kidney
The respiratory system and the circulatory system work together to transport oxygen to cells throughout the body. The respiratory system brings oxygen into the body through breathing, while the circulatory system carries oxygen-rich blood to tissues and organs.
