Question

Function of the pericardium include all of the following except, physical barrier to extracardial infections and inflammations, affects heart rate affects BP aids cardiac contraction. The chamber of the heart that endures the highest pressure is the: Rt. Atrium Lt. atrium Lt. ventricle Rt. Ventricle none of the above. During ventricular diastole valve(s) is (are) open. the semi lunar the atrioventricular neither both Oxygenated blood flows through the: superior vena cava pulmonary veins pulmonary arteries coronary veins. The complex represents the sum of all ventricular muscle cell depolarization> PRS QRS QT interval P. Pressure in the left ventricle must exceed pressure in the before the left ventricle can eject blood. superior vena cava coronary sinus inferior vena cava pulmonary veins aorta. The resting heart in normal person is primarily under the control of the nervous system. sympathetic parasympathetic somatic spinal The coronary blood vessels are directly by branch of the autonomic nervous system.

Explanation / Answer

1.C

Pericardium has no role in blood pressure regulation

2.C

Left ventricle endures the highest pressure as it pumps blood to all parts of the body.

3.B

atrioventricular valve opens during ventricular diastole

4.B

Pulmonary vein carries oxygenated blood from lungs to the heart

5. B

QRS complex shiws the ventricular depolarization in the electro cardiogram

6.E aorta

7.B parasympathetic

8 parasympathetic branch
