C Correct answer
Explanation

Blood allows heat transfer of heat from deeper tissues to the surface of the body where it can be lost. Hormones are carried by blood from endocrine glands to place of use, Also glucose and other nutrients are transported from alimentary canal through blood to different cells in the body.

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

  1. By changing the temperature of the body

  2. By producing nutrients

  3. By circulating from one part to other

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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'.
