Answer:
I started out as glucose, got converted to pyruvate, after which I got oxidised by Oxygen to become CO2

My glucose molecules were broken down into pyruvate, and I stayed that way for a while, as I made my way to the mitochondria of the child's cells. Once I got to the mitochondria, I met my old friend oxygen, who reacted with me to turn me into the molecule I am today - C02.
If you want to know how I escaped the child's body, that's easy - I simply snuck out his nose while he was breathing one cold dark night.
Answer:
The correct answer is a) It brings a transport liquid into close contact with all cells in the body.
Explanation:
The circulatory system helps in bringing the blood which is a transport liquid in close contact with the cells present in our body. This helps in gas exchange between cells and blood. The circulation of blood in the body occurs by the pumping of blood by the heart into arteries, veins, and capillaries.
This circulation of blood plays many other vital functions like transport of nutrients to the cells, transport of waste products from the cell to outside the body, transport of hormones, maintenance of body temperature, etc.
So all these processes become possible when transport liquid comes in contact with the cells. Therefore the right answer is a.
