After catching her archenemy, Xena has lived a long and productive life. She is now 85 years old and has suffered gradual changes to her rib cage: there has been calcification and reduced motility of the rib articulations. She finds herself short of breath when trying to perform actions that previously caused her no difficulty. Consider Xena’s blood pressure of 105/66 mmHg. Calculate her mean arterial pressure (MAP) and state if Xena’s present MAP is considered physiological. Explain how blood vessel diameter and arterial compliance/elasticity are expected to change as we age.

Which of the following statements best describes the function of the pulmonary arteries or veins? Pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs.
