What circuit represents blood traveling from the heart to the organs of the body; back to the heart again?
A
Systemic
B
Coronary
C
Pulmonary
D
Double
Explanation: 

Detailed explanation-1: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-2: -Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

Detailed explanation-3: -The systemic circuit transports blood between the heart and other parts of the body. The aorta, which arises from the left ventricle of the heart carries oxygenated blood from the heart to all parts of the body.

Detailed explanation-4: -Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.

Detailed explanation-5: -In the systemic circulation, the left ventricle of the heart serves as the pumping chamber that circulates blood throughout the body.
