Solution

The correct option is B A- Superior venacava, B- Inferior venacava, C- Right atrium, D- Right ventricle, E- Pulmonary artery

Superior venacava is also called precaval vein, which collects blood from anterior parts of the body. The function of inferior venacava is to collect blood from posterior parts of the body. The right upper chamber of the heart is right atrium which receives deoxygenated blood from the body through the venacava. It is then pumped into the right ventricle, sending it to the lungs to be oxygenated. Pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart.

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. Identify the correct option.
Statement 1: Blood from venacava and pulmonary veins enters the right and left atria respectively.
Statement 2: The aperture between the atria and the ventricles is closed by valves.

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.
