Epithelial cells that line the villi of the small intestine absorb nutrients into the blood and release wastes out of the blood for removal from the body. Ideally, an epithelial cell has a
large surface area for greater absorption of nutrients, but it is also important for
epithelial cells to have a low volume, so nutrients can quickly pass to other cells, Predict

elimination

Calvin ate a candy bar, which caused his body's blood glucose levels to become unbalanced. his body responded by initiating a feedback mechanism to return his body to homeostasis. place the steps of this feedback mechanism in order, starting with the blood glucose imbalance that occurred after calvin consumed the candy bar. a) calvin's blood glucose levels decreased. b) calvin's pancreas stopped secreting insulin. c) calvin's body cells started to take up glucose and store it as glycogen. d) calvin's blood glucose levels increased. e) calvin's pancreas started secreting insulin.
