No. The circulatory system consists of the veins and arteries. They are the way food and oxygen are transported around the body. They take food and oxygen to muscles and organs
This is accomplished by the circulatory system - from the arteries, to the arterioles, down to the tiniest of capillaries, which feed all tissues, including muscle and bone. Exchange finally occurs between the capillary membrane and the cell membrane.
Humans are said to have a circulatory system because the arteries that feed from the heart and go to the capillaries and to the veins back to the heart or make circle with no outlet.
Every part of the body requires oxygen in order to maintain metabolism and the circulatory system reaches all body tissues. Arteries are progressively split into smaller and smaller feed vessels (arteriole). At the final stage the blood flows into and out of the capillaries.
The circulatory system is necessary in a complex multicellular organism like a human because oxygen must be circulated throughout the body to feed the organs and tissues. The blood also removes waste from the organs and tissues (the exchange of gases takes place during circulation). Tiny vessels must pass near every cell in the body and there are a trillion of them.
The hydra takes in nutrition through the use of tentacles. The muscles of the organism absorb the nutrients as there is no circulatory, respiratory or urinary system.
The aorta is part of the circulatory system. It is the largest artery in the body and leads from the heart down through the abdomen and splits into smaller blood vessels that feed the lower half of the body (such as the femoral arteries).

Basically, they are linked to each other. The circulatory system gets oxygen from the lungs, while the respiratory system gets blood from the circulatory system necessary to feed its cells. The pulmonary circulatory system is part of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, through the pulmonary artery, to the lungs and returned, oxygenated, to the heart through the pulmonary vein. Oxygen deprived blood from the superior and inferior vena cava, enters the right atrium of the heart and flows through the tricuspid valve (right atrioventricular valve) into the right ventricle, from which it is then pumped through the pulmonary semilunar valve into the pulmonary artery to the lungs. Gas exchange occurs in the lungs, whereby CO2 is released from the blood, and oxygen is absorbed. The pulmonary vein returns the now oxygen-rich blood to the left atrium.
Muscles are tissue found in animal organisms. The venus flytrap is a plant, it does not have muscles.

Hmm; in a sense, yes. A more complete understanding would have arteries feeding capillaries, which feed the muscle or organ fresh blood, which is returned to the circulatory system by veins. Arteries carry oxygenated blood; veins return the now oxygen-depleted blood to the lungs, then heart, and back to the arteries, in brief.
