Question

Connection between digestion and cellular respiration

Answer 1

The digestive tract provides the nutrient molecules, through the process of digestion, while the respiratory tract provides oxygen. As such, the two systems work together to give your cells the ingredients they need to produce energy, which they use to communicate, build cellular products and grow.

Answer 2

The respiratory system brings oxygen into the lungs when you breathe. The digestive system breaks food down into nutrients such as glucose. ... The circulatory system also transports oxygen from the lungs to the cells. Now the cells have what they need for cellular respiration: oxygen and glucose.
