Which of the following parts of the conductivity system of the heart sends the electrical message directly to the purkinje fibres?
Bundle of His
What is the name of the valve that prevents backflow into the right atrium?
Tricuspid atrioventricular valve
Which blood vessel carries blood from the heart to the systemic circuit?
Aorta
Which blood vessel carries blood from the heart to the lungs?
Pulmonary artery
Where is the tricuspid valve located?
The tricuspid valve is found between the right atrium and the right ventricle.
Which part of the conductivity system of the heart tells the atria to contract?
Sinoatrial node (SA) node
What is the name of the valve that prevents backflow into the left ventricle?
Aortic semilunar valve
Which chamber of the heart receives deoxygenated blood returning to the heart?
Right atrium
Which of the following parts of the conductivity system of the heart signals the ventricles to contract?
Purkinje fibers
What is the pathway blood travels through the heart
The First Step → The blood moves from the right atrium to the right ventricle.,
The Second Step → The blood moves through the pulmonary artery.,
The Third Step → The blood moves into the capillary beds of the lungs.,
The Fourth Step → The blood releases the carbon dioxide, and then is oxygenated.,
The Fifth Step → The blood moves into the pulmonary veins.,
The Sixth Step → The blood moves to the left atrium.
Which blood vessel(s) carries blood into the left atrium?
Pulmonary veins
Which blood vessel carries deoxygenated blood back to the heart?
Vena cava
