Describe the Cardiac Cycle correct answer: • Blood enters the heart through the superior vena cava and the pulmonic veins. Atria builds up in pressure causing blood to go through ventricles via the tricuspid valve and mitral valve. • The closure of Tricuspid/mitral valves is s1, which is the start of systole. • As pressure builds up in the vetricles, blood is ejected via the aorta, and to the lungs. When the ventricles decrease in pressure, this causes the Aortic and pulmonic valves to ...
