Clinical features of acute spasmodic laryngitis include a croupy cough, a tendency to recur, and occurring sudden, often at night. High fever is a feature of acute epiglottitis and purulent secretions are seen with acute tracheitis.

During moderately strenuous exercise there is a huge increase in cardiac output (up to 7-fold in trained athletes!) and a dramatic redistibution of blood flow to individual organs. Which of the following accurately describes changes in blood flow during exercise, compared to blood flow at rest?
A. Vasodilation of arterioles feeding digestive tract and liver leading to an overall increase in blood flow B. Pronounced decrease in overall blood flow to the brain C. An overall decrease in blood flow to the skin per minute D. Widespread vasodilation of arterioles in exercising skeletal muscles leading to a large drop in total peripheral resistance E. Pronounced increase in overall blood flow to the brain F. As much as 20-fold increase in overall blood flow to skeletal muscle in trained athletes G. An overall increase in blood flow to the skin per minute H. Blood flow to cardiac muscle remains constant I. Vasoconstriction of arterioles feeding liver and digestive tract leading to an overall decrease in blood flow J. Increased fraction of cardiac output going to skeletal muscle with no change in total peripheral resistance K. Decreased % of cardiac output to the brain but little change in the amount of blood reaching the brain
