BIOXI18: BODY FLUIDS AND CIRCULATION

339429 SA node is called the pace maker of the heart. Why?

1 It initiates and maintains the rhythmic contractile activity of heart.
2 It delays the transmission of impulse between the atria and ventricles.
3 It gets stimulated when it receives neural signal.
4 It maintains the pace of the heart beat
BIOXI18: BODY FLUIDS AND CIRCULATION

339430 In a study of a blood vessels \(\mathrm{A}, \mathrm{B}, \mathrm{C}\) and \(\mathrm{D}\) in man. Vessel 'A' carried pure blood away from heart, Vessel 'B' carried impure blood towards heart, Vessel ' \(C\) ' carried pure blood into the heart musculature while Vessel 'D' carried impure blood away from heart. The correct name of four vesssels can be

1 Systemic aorta - A, Vena cava - B, Coronary artery - C, Pulmonary artery-D
2 Coronary artery - A, Pulmonary vein - B, Pulmonary artery \(-\mathrm{C}, \mathrm{SVN}-\mathrm{D}\)
3 Pulmonary vein - A, Pulmonary artery B, Coronary artery - C, Vena cava - D
4 Systemic aorta - A, Pulmonary vein - B, Coronary artery \(-\mathrm{C}\), Pulmonary artery- D
