A circulatory system (cardiovascular system in biology classes) is an organ system that moves substances to and from cells; it can also help stabilize body temperature and pH (part of homeostasis). There are three types of circulatory systems (from simplest to most complex): no circulatory system, open circulatory system, and closed circulatory system.

The circulatory system is the system of organs whose main function is circulation of substances to differerent organs. The medium through which the substances are carried is blood. The blood carries oxygen and food particles mainly. The main organs in this system are the heart, blood, veins, arteries and capillaries. This system is extremely essential for all the organs of the body to function properly. Without the substances the blood carries, all the organs would break down and the human being would die. That's why heart diseases are so dangerous, because it pumps the blood. Any fault in that could prove to be fatal.

Circulatory System:
Cardiovascular system:
the heart and blood vessels considered as a whole.
Vascular system
the cardiovascular and lymphatic systems collectively.
On average, your body has about 5 liters of blood continually traveling through it by way of the circulatory system. The heart, the lungs, and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey.
The body's circulatory system really has three distinct parts: pulmonary circulation, coronary circulation, and systemic circulation. Or, the lungs (pulmonary), the heart (coronary), and the rest of the system (systemic). Each part must be working independently in order for them to all work together.

it is one of the 7 systems in our body...from the word circulation...what is the liquid performing a lifetime cycle in our body? BLOOD.exactly...thus circulatory system, it involves the sensitive organs inside a human body which regulates the flow of blood...there are various organs comprising this system..we have the heart as the prime organ and so on...ihope this wud help u...i only share a bit about it...so if u really wanna knpow the etails...u can look into biology books..it's really interesting....^^

In human biology, the circulatory system consists of the heart and connecting arteries and veins. Its purpose is to transport oxygen and nutrients to the various organs of the body and return waste products to the lungs, liver, and kidneys to be eliminated.
The heart is comprised of 4 chambers, 2 atria and 2 ventricles. The atria receive blood from the veins and pump it into the ventricles. The ventricles pump the blood out of the heart into the arteries.
It is called the circulatory system because the blood flows in a closed "circle" (i.e. it comes back to where it begins) The path of blood is as follows starting from the right atrium:
right atrium
right ventricle
pulmonary artery
pulmonary arterioles
lung capillaries
pulmonary venules
pulmonary vein
left atria
left ventricle
aorta
arteries
arterioles
capillaries
venules
veins
vena cava
right atrium

According to the currently accepted big bang theory, the universe arose from an initial explosion, involving the expansion of matter from an extremely condensed state. Several problems were unresolved, however, in the original formulation of the big bang theory. The state of matter at the time of the explosion was such that normal physical laws would not apply. The degree of uniformity observed in the universe today was also hard to explain, because according to the big bang theory the universe would have expanded too rapidly to allow uniformity to develop.
Guth based his inflationary theory on the work of such physicists as Stephen Hawking, who had studied extremely strong gravitational fields, such as that in the vicinity of a black hole or in the very early universe. This work showed that matter, including all the matter in the universe, could be created by quantum fluctuations in “empty” space, under such conditions. Guth's work, then, made use of unified field theory to show that a number of phase transitions could take place in the first moments of the universe, and that one region of that original chaotic state could have inflated rapidly to allow the observable region of the universe to form.

Its a system in human body which regulates and circulates blood,air and nutrients to every part of the body.

Closed circulatory system. I suppose the TIPSY is visiting yahoo answers for the first time. Asking such questions demean the purpose of the site.

Any organ system which provides the transport of all the neccessary substance like - minerals,hormones,medicine,oxygen,co2 etc. etc.
There are 2 main c.s : one which transports materials thru blood and the other which transports material thru lymph

it is spelled circulatory
it is the system which includes your heart, veins and arterys. i pumps blood through your body to transport nutrients and oxygen to all the cells
