Introduction:
The circulatory system is one of the most important systems in the human body. It is also called as the cardiovascular system; it nourishes organs with oxygen along with other important minerals and at the same time takes away carbon di-oxide and other waste products from the blood. The circulatory system flows with blood through vessels; there are three different vessels, namely the arteries, veins, and capillaries. The arteries carry oxygenated blood to organs, and veins carry de-oxygenated blood from organs, while the capillaries act as a connection in between veins and arteries.

- Several years ago the deaths of several airline travelers led to warnings about economy-class syndrome. The idea is that economy-class passengers dont have as much leg room as passengers in more expensive seats, so they are more likely to sit essentially motionless for long periods on flightsconditions that may allow blood to pool and clots to form in the legs. This condition is called deep-vein thrombosis, or DVT. Given what you know about blood flow in the veins, explain why periodically getting up and moving around in the planes cabin during a long flight may lower the risk that a clot will form.arrow_forwardDescribe the structure of a capillary. Explain how this unique structure is suited to its function (the site of exchange of materials between blood and nearby cells).arrow_forwardExplain how a tissue autoregulates local blood flow based on metabolic needs.arrow_forward
