Answer the following question given this paragraph: Constriction and dilation allow the circulatory system to change the amount of blood flowing to different organs. For example, during a fight-or-flight response, dilation and constriction of blood vessels allow more blood to flow to skeletal muscles and less to flow to digestive organs. Dilation of blood vessels in the skin allows more blood to flow to the body surface so the body can lose heat. Constriction of these blood vessels has the opposite effect and helps conserve body heat. Q: Constriction and dilation allow the circulatory system to change the amount of blood flowing to which body parts? Choices: - arteries - tissues - muscles - organs A:
organs
