C. Ventricular filling
D. Isovolumetric relaxation - CORRECT-ANSWERSB. Isovolumetric
contraction

A 40-year-old patient has been admitted to the critical care unit after
sustaining multiple injuries from a cave-in accident this morning. X-ray
confirm multiple fractures, including the left femur. During the afternoon he
