Question

What is the process by which substances in food are transformed into body tissues and provide energy for the full range of physical and mental activities that make up human life?

Answer 1

The absorbed food materials are transported by blood and lymph. Lymph is finally transferred to the blood circulation. The blood transports absorbed food materials to different body cells where food materials become integral component of the living protoplasm and are used for energy, growth and repair. This is called assimilation of food.
