- Q2Which part of the digestive system contains structural adaptions called villi that increase the surface area for the absorption of food?large intestinestomachesophagussmall intestine30s
- Q3If too much water is removed from undigested food, the feces harden and constipation occurs. This malfunction affects which part of the digestive system?stomachlarge intestinesmall intestineesophagus30s

- Q5Which of the following systems breaks food into nutrients that can be used by the body?respiratoryreproductivecirculatorydigestive30s
- Q6How do nutrients, absorbed by the small intestine, travel to the individual cells of the body?The nutrients move from the small intestine directly to the live and then move through the lymphatic system to the body cells.The nurtients are absorbed from the small intestine into the blood and move through the circulatory system to the body cellsThe small intestine forces the nutrients into the kidneys where the nutrients are then dissolved in fluids used by the body cellsThe body cells send nerve impulses indicating a lack of nutrients to the small intestine and the small intestine sends the nutrients back to the cells.30s

- Q15Why do humans need to take in food?Food is a type of fuel, meaning it can react with other substances to produce energyFood is a type of fuel, meaning it cannot react with other substances to produce energyHumans do not need to take in food, they can create energy on their own through cellular respiration30s
