Glucose is absorbed from the food in our small intestine. Inside the small intestine we have small finger like structures called villi. The glucose is absorbed by the villi. The glucose is absorbed (moves through) the villi and enter our blood system. Glucose is transported by our blood to all the cells in our bodies. Respiration takes place in our cells (in the mitochondria of cells). Respiration is where glucose (our bodies fuel) combines with oxygen (we breath in) to give us ENERGY, carbon dioxide and water.
