Question

Match the following terms in column 1 with their description or definition in column 2.

Column 1. Column 2

Mitral Valve.                   the right atrioventricular valve

Semilunar Valve.            the right semilunar valve

Tricuspid Valve              the left semilunar valve

Aortic Valve.                   the heart valves between the
                                          atria and great veins

                                          heart valve between ventricle
                                          and great arteries

                                          the left atrioventricular Valve

Answer 1

Column 1	Column 2
Mitral valve	the left atrioventricular Valve
Semilunar valve	the right semilunar valve
tricuspid valve	the right atrioventricular valve
Aortic valve	heart valve between ventricle and great arteries the left semilunar valve

The human heart is composed of 4 chambers they are the right atrium,right ventricle,left atrium and the left ventricle.

The venacavae opens into the right atrium and the right atria and ventricle is separated by the tricuspid valve that prevents the backflow of the blood during contraction of the right ventricle.The blood then enters the pulmonary artery guarded by the semilunar valve.The blood reaches the lungs,gets oxygenated and reaches the left atria via the pulmonary vein.The blood from the left aorta enters the left ventricle.They are separated by the mitral valve.The blood is then pumped by the left ventricle into the aorta.The aorta is guarded by the aortic semilunar valve.
