What prevents the backflow of blood in the heart?
The tricuspid valve controls the flow of blood between the right atrium and the right ventricle. When the right ventricle pumps blood to the lungs,...
What prevents the backflow of blood into the heart during contraction?
A set of valves open and shut firmly when the heart pumps blood. These valves keep blood flowing in only one way, preventing backflow. The tricuspi...
What keeps the blood flowing in only one direction?
Valves keep blood flowing in the right way. Both are semilunar valves--they are shaped like a half moon. They can get clogged up with junk that may...
What keeps the blood moving in the right direction?
The flow of blood in the heart is controlled by valves, which ensure that it flows in the appropriate direction. Blood cannot flow backwards throug...
What valve prevents blood from flowing back?
When the right ventricle fills up, the tricuspid valve shuts, preventing blood from flowing backward into the right atrium as the ventricle contrac...
Which side of the heart pumps oxygen-poor blood to the lungs to be re-oxygenated?
The right side of the heart pumps oxygen-poor blood to the lungs to be re-oxygenated. For this reason, the right side of the heart is considered the pulmonary circuit pump. The left side of the heart pumps blood to the body, and is therefore considered the systemic circuit pump.
Which area of the heart has the exit through which the blood leaves?
Match the area of the heart with the "exit" through which the blood leaves: Right atrium.
What is the first sound of the heart?
The first heart sound (the "lub" of the "lub-dup") is generated by the closure of the atrioventricular valves.
Which node initiates heart contraction?
The sinoatrial node, by spontaneously depolarizing faster than the atrioventricular node, initiates heart contraction.
Which ventricle empties into the pulmonary circuit?
The left ventricle empties into the pulmonary circuit.
Where does the impulse originate from in the heart?
SA node, AV node, bundle of His, bundle branches, and Purkinje fibers. The impulses of the heart originate at the SA node (pacemaker). The impulse is then transmitted to the AV node (atrioventricular node), where the impulse slows down to allow the atria to completely contract and thereby fill the adjacent ventricles.
Which veins deliver oxygenated blood to the left atrium?
The pulmonary veins deliver oxygenated blood to the left atrium.
Which side of the heart pumps oxygen-poor blood to the lungs to be re-oxygenated?
The right side of the heart pumps oxygen-poor blood to the lungs to be re-oxygenated. For this reason, the right side of the heart is considered the pulmonary circuit pump. The left side of the heart pumps blood to the body, and is therefore considered the systemic circuit pump.
