Juaben is pregnant. Over the next 40 weeks, her uterus will enlarge as the placenta develops and the fetus grows, her abdomen will add skin to accommodate distension, her breasts will grow, her blood volume will increase, and many other changes will occur. Using what you have learned about basic cardiovascular physiology, predict how parameters such as blood pressure and cardiac output will change. (Note that the fetus has a separate cardiovascular system, which does not need to be considered.) Explain your answer.
