PSIO 202 Study Guide - Midterm Guide: Ventricular Septal Defect, Bainbridge Reflex, Tricuspid Valve
Document Summary
Anatomy 202 - cardiovascular system summary and study guide: functions of the heart - systemic flow of blood throughout the body and pulmonary flow of blood to and from the lungs. Valves - they keep the blood flowing in the right direction. Atrioventricular valves are the two valves between the atria and ventricles. One is the tricuspid valve and the other is the mitral valve. The tricuspid valve is between the right atrium and the right ventricle and the mitral valve is between the left atrium and the left ventricle. These two valves are tethered to the walls of the heart by the papillary muscles. Chordae tendinae keep the valves from flipping backwards. The two semilunar valves are the pulmonary valve and the aortic valve: the interventricular septum has a membranous part and a muscular part. The pericardium has two layers, an inner and outer layer and in between them, there is a gap with a little bit of fluid.
