	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

• A. $1-c;2-a;3-d;4-b$
• B. $1-a;2-c;3-d;4-b$
• C. $1-c;2-a;3-b;4-d$
• D. $1-a;2-c;3-b;4-d$

Answer 1

The correct option is A $1-c;2-a;3-d;4-b$

The major blood vessels associated with the four chambers of the heart are:

(i) Superior and inferior vena cava, which carries deoxygenated blood to the right atrium

(ii) Pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for purification.

(iii) Pulmonary vein carries oxygenated blood from the lungs to the left atrium.

(iv) Aorta carries oxygenated blood from the left ventricle to all the different parts of the body.
