a closed circulatory system is the type humans have.the blood flows through the blood vessels like arteries,veins and capillaries.in an open system,the blood vessels are either completely absent or not completely closed.

The heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. \n\nThe aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.\n\nThe right coronary artery supplies blood mainly to the right side of the heart. The right side of the heart is smaller because it pumps blood only to the lungs.\n\nThe left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart. The left side of the heart is larger and more muscular because it pumps blood to the rest of the body.

Circulatory - keeps the blood and nutrients circulating to all vital organs\nRespiratory - provides oxygen to the blood system, and eliminates CO2\nNeurological - controls the other systems\nDigestive - provides the nutrients circulated by the blood system, and excretes the waste products, ridding the body of toxins\nRenal - maintains healthy fluid balance so that the blood can flow through the body with ease, also eliminates waste products, ridding the body of toxins

>Insects have an open circulatory system.\nAn open circulatory system is an arrangement of internal transport present in some invertebrates like mollusks and arthropods in which circulatory fluid in a cavity called the hemocoel bathes the organs directly and there is no distinction between blood and interstitial fluid; this combined fluid is called hemolymph (also spelled haemolymph). Muscular movements by the animal during locomotion can facilitate hemolymph movement, but diverting flow from one area to another is limited. When the heart relaxes, blood is drawn back toward the heart through open-ended pores.\n\n'Hemolymph fills all of the interior (hemocoel) of the body and surrounds all cells.\n\nHemolymph is composed of water, inorganic salts (mostly Na+, Cl-, K+, Mg2+, and Ca2+), and organic compounds (mostly carbohydrates, proteins, and lipids). The primary oxygen transporter molecule is hemocyanin.\n\nThere are free-floating cells, the hemocytes, within the hemolymph. They play a role in the arthropod immune system.

The vertebrate cardiovascular system includes a heart, which is a muscular pump that contracts to propel blood out to the body through arteries, and a series of blood vessels. The upper chamber of the heart, the atrium (pl. atria), is where the blood enters the heart. Passing through a valve, blood enters the lower chamber, the ventricle. Contraction of the ventricle forces blood from the heart through an artery. The heart muscle is composed of cardiac muscle cells.

Humans have a closed circulatory system.  It is when the blood is contain in the veins and arteries.  Where the arteries take blood to the body and the veins take it directly back.  In an open system the heart pumps blood out into an open area where the blood just flows over the different body parts and then comes back to the heart on its own.  An open circulatory system is extremely inefficient and a lower form of evolution.

Wow, I don't know if they'd let me type 1000 pages on the subject to cover your question even close to adequately, but I'll give the Reader's Digest version a go...\n\nThe circulatory system is a liquid highway your body uses to transport oxygen and nutrients everywhere they need to go and waste products away from those tissues to be disposed.  The heart is a just a positive displacement pump that keeps your blood flowing through the arteries and veins.  Lungs serve as an interface between the circulatory system and the outside world, a place where oxygen can be drawn into the body through the thin membranes of the alveoli to be absorbed by red blood cells and bound by the hemoglobin molecules within, to be carried to every point in the body.  The lungs are also the place where carbon dioxide, also bound by hemoglobin and brought to lungs for disposal, can pass back out and be exhaled.  Much of this system is automatic and completely involuntary, and some of it isn't even controlled by the brain, at least not directly -- you can hold your breath, for instance, but you do have to consciously think about not breathing.  Your brain does have some say in how fast everything works, sending a message to your heart and lungs during times of stress or exertion to say, "Hey!  We're working kind of hard here; maybe we need more oxygen to the muscles!  Work a little faster, please!" and you start to breathe hard and your heart starts to beat faster.

Arteries are muscular blood vessels that carry blood away from the heart. They are contrasted with veins, which carry blood toward the heart.\n\nThe circulatory system is extremely important in sustaining life. Its proper functioning is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, maintenance of optimum pH, and the mobility of the elements, proteins and cells of the immune system. In developed countries, the two leading causes of death, myocardial infarction and stroke each may directly result from an arterial system that has been slowly and progressively compromised by years of deterioration.

Let's just call it Blood Pathway =)\n\nfrom ur system (outside the heart) unoxygenated blood --> right atrium --> tricuspid valve ---> right ventricle ---> pulmonary artery --> lungs (oxygenates blood) ---> pulmonary vein (blood is already oxygenated) ---> left atrium --> bicuspid valve --> left ventricle ---> system (outside heart) \n\nthe cycle goes back... \n\nAlways remember that the atria are the receiving chambers of the heart while the ventricles are the pumping chambers of the heart.\n\nThere are three varieties of blood vessels: arteries, veins, and capillaries. During blood circulation, the arteries carry blood away from the heart. The capillaries connect the arteries to veins. Finally, the veins carry the blood back to the heart.

R. atrium to r. ventricle, into the pulmonary artery, which carries deoxygenated blood to the lungs. Once blood receives oxygen in the lungs, it returns to the heart via the pulmonary veins. Here it is emptied into the left atrium, then on to the left ventricle, which pumps the oxygenated blood into the aorta and thence out into the systemic circulation.

Through the hepatic arteries and the hepatic veins.\n\nTechnically, the blood will go from the abdominal aorta to the liver theough the hepatic arteries, then the arterioles, then the capillaries of the liver through to the venuoles and then the veins which lead back to the hepatic veins which lead to the inferior vena cava which lead to the heart. The heart pumps the blood through the lungs, back to the heart and out the aorta where it travels back to the abdominal aorta.

Coronary Circulation is the circulation of through the vessels of the heart - the one that supplies blood to the heart itself.

Well, the pulse is the blood passing in your arteries.  It speeds follows the beating of the heart.  The rate of the heart is controled mainly by the hypothalamus that reacts to the blood need in the brain.

The time it takes blood to circulate in the human vascular system varies with age, body size and condition, and whether the person is resting or engaged in vigorous physical and/or emotional activity. Nevertheless, on average the blood fully circulates in the human body some seven to eight times per minute.

Through the veins. From the toe, through the foot, up the calf, past the knee, up the thigh, through the abdomen to the liver. If you want a good answer, read your book and do your homework.
