Question

How blood maintains the physiological co-operation of the body?

• A. By changing the temperature of the body
• B. By producing nutrients
• C. By circulating from one part to other
• D. All of the above

Answer 1

The correct option is C By circulating from one part to other

The main function of the cardiovascular system is, therefore, to maintain blood flow to all parts of the body, to allow it to survive. Veins deliver used blood from the body back to the heart. In the lungs, the blood picks up oxygen that we breathe in and gets rid of carbon dioxide, which we breathe out.

So, the correct option is 'By circulating from one part to other'.
