//Fill in the blanks



//Numericals



//Match the following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Pulmonary circulation -> Circulates blood between the heart and lungs
=Systemic circulation -> Circulates blood between heart and body tissues
=Left ventricle -> Pumps oxygenated blood to the body
=Right atrium -> Receives deoxygenated blood from the body
=Pulmonary vein -> Returns oxygenated blood to the heart
}
