Question

what is Double Blood circulation. how it works. HEPL FAST.............!!

Answer 1

hey mate here is your answer......

Double blood circulation is simply what happens in our body every single moment. It is simply Blood travelling in two seprrate systems or circulatory loops simultaneously without any intermixing.

In our body, blood passes through two different circulations in one loop or circuit.They are:

The Pulmonary Circuit: Consisting of the Right ventricle, pulmonary artery, lung vasculature, pulmonary vein and left atrium. The aim is basically to oxygrnate the deoxygenated blood by running it through a pitstop thst is the lung. It is a comparatively shorter circuit.The Systemic Circuit: This consists of left ventricle, aorta, systemic atreries, capillaries, systemic veins, superior and inferior vena cavae and right atrium. This longer and more circuitous route is to eventually deoxygenate the oxygen rich blood by delivering it at tissue level.

It can be noticed that both systems of circulation 'flow' in to one another, but they never mix. Deoxygenated blood remains in the right heart and oxygenated blood remains in the left heart. Only in defects of the heart does this happen- atrial septal defect, ventricular septal defect, tetrology of Fallot, patent ductus areteriosus etc . Quite rarely but.

Hope this helped............
