Collect impure blood from different parts of body through venacava
Collect impure blood from right atrium and pump it through pulmonary artery to lungs for purification or take oxygen by removing CO2
Collect pure blood from pulmonary vein and squeeze to right ventricle
Carry pure blood from lungs to heart(All other veins carry impure blood
Carry impure blood to lungs (all other arteries carry pure blood)
Carry pure blood to diff parts of the body
Bring blood back to heart from different parts of the body

Inferior venacava or venacava from lower side
Right atrium
Right ventricle
Left ventricle
Pulmonary artery (with impure blood to lungs from right ventricle
Left atrium
Vena cava
Aorta
Label any 5 parts
Interpret the picture on the basis of the above given picture.
Then ventricle contracts (third figure)
First atrium contracts (second figure)
Impure blood in right atrium passes to right ventricle and pure blood in left atrium passes to left ventricle.
Impure blood in right ventricle passes to pulmonary artery to lungs and pure blood from left ventricle pumps into aorta which take pure blood to diff parts of the body.
Colour right atrium and ventricle in blue and right atrium and ventricle in red . cover it with a flap in which Structure of heart is written.
Coronary artery
The blood vessel that collect impure blood from heart muscles
Label coronary artery.
