Q. Match the following chambers of the heart with the respective blood vessels:

	Column A		Column B
$1.$	Right atrium	$a .$	Pulmonary vein
$2.$	Left atrium	$b .$	Aorta
$3.$	Right ventricle	$c .$	Superior vena cava
$4.$	Left ventricle	$d .$	Pulmonary artery

Q. Read the statements and select the option which best describes the process that occurs during systematic circulation.
(i) The left atrium receives the oxygenated blood through the pulmonary veins. The left ventricle pumps the blood through the aorta to various parts and the de-oxygenated blood reaches right atrium.
(ii) The left atrium receives the oxygenated blood through pulmonary veins and pumps the blood through the aorta to various parts and the de-oxygenated blood reaches the right atrium.
(iii) The left atrium receives de-oxygenated blood and pumps into left ventricles which in turn pumps into pulmonary artery for oxygenation.
(iv) The right atrium receives the de-oxygenated blood and pumps into pulmonary artery for oxygenation.
