OBE Cardiovascular Heart & Blood Vessels 2020

The following arteries supply oxygenated blood to the brain EXCEPT

• femoral artery

• internal carotid artery

• common carotid artery

• brachiocephalic artery

Which of the following is CORRECT about the structure of the heart?

• surrounded by pleural layer

• receive oxygenated blood supply from coronary sinus

• sinoatrial node is located at the right atrium of the heart

• right ventricle has the thickest layer of myocardium

In the conduction system of the heart, impulse that travels to the Purkinje fibers will cause

• atrial systole

• atrial diastole

• ventricle diastole

• ventricle systole

The highest blood pressure can be detected in the

• veins

• venules

• arteries

• arterioles

Pulmonary circulation starts from

• left ventricle to the aorta

• left ventricle to the right atrium

• right ventricle to the lungs

• right ventricle to the right atrium

I. External subclavian vein

II. Subclavian vein

III. Superior mesenteric vein

IV. Hepatic vein

The above veins which carry deoxygenated blood into the inferior vena cava are

• I and II

• II and III

• III and IV

• I and IV

Which of the following blood vessels carry the highest concentration of oxygenated blood?

• pulmonary vein

• pulmonary artery

• superior vena cava

• radial artery

Tunica adventitia layer in the blood vessel is made up of

• fibrous tissue

• smooth muscle

• skeletal muscle

• epithelium squamous

The 'lub' heart sounds can be heard during

• atrium systole

• atrium dyastole

• ventricular systole

• ventricular dyastole

During ventricle systole, blood will be pumped from

• ventricle to aorta

• atrium to ventricle

• atrium to pulmonary artery

• ventricle to pulmonary vein
