Answer 1

Name	Function
Pulmonary vein	Brings oxygenated blood from lungs to the heart for circulation throughout the body.
Thrombocytes	Helps in clotting of blood.
Semilunar valves of the heart	They prevent the backflow of blood from the pulmonary artery and aorta into the heart.
Bundle of His	They carry the wave of excitation from atrioventricular node to the.ventricles.
Coronary artery	It carries blood to the muscles of heart.
Bicuspid valve	It prevents the reverse flow of blood from the left ventricle into the left auricle.
Haemoglobin	It is the respiratory pigment, helps to carry O2 to the body parts.
Vitamin K	Helps in clotting of blood.
Pericardium	It protects the heart.
Pulmonary artery	To Transports deoxygenated blood to the lungs.
Lymph	It transports fatty acids and glycerol, it also protects the body against microorganisms.
W.B.C.	To fight against microorganism by producing antibodies.
R.B.C.	To transports oxygen to the body parts.
Platelets	Helps in blood clotting.
Tricuspid valve	It prevents the reverse flow of blood from the right ventricle into the left auricle.
Chordae tendineae	To keep the cuspid valves in position.
Vena cava	To carry deoxygenated blood from the body parts to the right auricle of the heart.
