Submissions without proper formatting, all required photos or sufficient responses will be rejected. Prelab Questions 1. Describe the pathway of blood traveling through the closed system of the circulatory system starting with the right atrium. The right atrium and right ventricle are where blood enters the heart initially. The right ventricle pumps blood to the lungs, where oxygen is added. Oxygenated blood from the lungs is returned to the left atrium through the pulmonary veins and the left ventricle. The left ventricle uses the aorta to transport blood to the body's organs. 2. What are the main resistance vessels of the circulatory system? The small arteries and arterioles are the primary resistive vessels in the cardiovascular and blood circulation systems. Because of their elastic nature, the vessels can expand and compress to change the resistance. 3. How are they (the resistance vessels you noted in Question 2) controlled? Arterioles constrict as a result of the action of the sympathetic nervous system. Vasopressin, another name for ADH, is a hormone that regulates arterioles
