Question
Chapter 33, Problem 2FIB
Summary Introduction
Introduction:
The heart has four chambers; two superior atrium, and two inferior ventricles. The chambers are divided into right and left sides by the septum. Main blood vessels of the heart are superior and inferior vena cavae, arteries, pulmonary veins, and the aorta.

- Which chambers of the heart receive blood, and which discharge it?arrow_forwardDetermine whether the statement is either true or false. To clearly hear the heart sound of the bicuspid valve, a stethoscope should be placed to the left of the sternum at the second intercostal space. At late diastole, the atria and ventricles are relaxed and the aortic semilunar valve is open. During ventricular contraction all the blood is forced out of the ventricles.arrow_forwardDrag the steps below and place them in the order of blood flow through the heart. First: Second: Third: Fourth: Fifth: Sixth: Seventh: Eighth: Ninth: Tenth: Flows through right atrial ventricular valve (tricuspid) Blood back flowing in aorta toward heart enters coronary circulation Flowing into the right atrium Out the aortic semilunar valve into the aorta Back to heart through the pulmonary veins to the left atrium Into the right ventricle Into the left ventricle Left atrium through left atrial ventricular valve (BICUSPID OR MITRAL) Out the pulmonary semilunar valve through the pulmonary arteries to lungs To the body through the aortic branchesarrow_forward
