Trace the path of blood through the mammalian heart starting with the Right Atrium

Question

1. Trace the path of blood through the mammalian heart starting with the Right Atrium. Use the following terms: Aortic Arch, Aortic Similunar Valve, Bicuspid (Mitral) Valve, Body, Descending Aorta, Left Atrium, Left Ventricle, Lungs, Inferior Vena Cava, Pulmonary Arteries, Pulmonary Similunar Valve, Pulmonary Veins, Right Atrium, Right Ventricle, Septum, Superior Vena Cava, Tricuspid Valve

Right Atrium —>

Answer 1

Using the human heart as an example

Right atrium-> tricuspid valve->right ventricle->pulmonary semilunar valve->pulmonary arteries->lungs->

pulmonary veins->left atrium->mitral valve->left ventricle->aortic semilunar valve->aortic arch->descending aorta->body->inferior or superior vena cava (depending on what part of the body the blood is coming from)

->right atrium

Blood does not cross the septum after birth except in pathologic conditions.
