The carotid artery of an animal is partially constricted proximal to the carotid sinus during a study. Which of the following cardiovascular changes most likely occurs in response to the constriction?   (My opinion is the question is referring to carotid clamping not carotid massage ( carotid massage is usually done on carotid sinus to rapidly lower heart rate)) A. Decreased heart rate B. Decreased systemic arterial pressure  C. Decreased venous return to the start D. Increased number of impulses from the carotid sinus  E. Increased total peripheral resistance.
