What else can I help you with?
What is a mantelpiece?
A piace of wood or stone that goes over a fire place.
Is cooking a hot dog over a fire conduction or convection?
convection
What causes the formation of the Ring of Fire?
Volcanoes around the Ring of Fire occur mainly where moving plates collide
If your 2000 Honda Prelude turns over but does not have fire when you try to start it what could be the problem?
Check fuel and fire. Pull a plug and smell for raw fuel, and check the plug and see if there is fire to the plug. If I checked the plugs and it is not getting fire or fuel at all what could cause that problem.
How many paintings did Norman Rockwell paint?
Norman Rockwell produced over 4,000 original works. Most of them were destroyed by fire or are in permanent collections.
What pacemaker of the heart initiates depolarization under normal conditions?
The primary pacemaker of the mammalian heart is the sino-atrial node. If the SA node fails, the atrioventricular node (AV node) takes over pacemaking.
What is power backup?
Whatever takes over when the main power supply fails.
What is a s.a.node?
The sinoatrial node is the impulse-generating pacemaker of the heart located in the right atrium of the heart. In other words - it makes your heart beat.Note that if the SA node fails for some reason, other nodes are ready to take over
Where on the rhythm strip is the P wave located for junctional rhythm?
P waves occur from the sinoatrial node and indicate the atrial component of a heart rate. Junctional rhythms occur when the AV node (below the sinoatrial node) takes over. Therefore, in most junctional rhythms there are no p waves.
What are the two escape pacemakers and their intrinsic rates?
The two escape pacemakers in the heart are the atrioventricular (AV) node and the Purkinje fibers. The AV node typically has an intrinsic rate of 40 to 60 beats per minute, while the Purkinje fibers have a lower intrinsic rate of about 20 to 40 beats per minute. These pacemakers take over when the primary pacemaker, the sinoatrial (SA) node, fails to generate impulses effectively.
What is a rhythm originating from the av node?
A rhythm originating from the atrioventricular (AV) node is known as a junctional rhythm. This occurs when the SA node fails to initiate the heartbeat, causing the AV node to take over as the primary pacemaker of the heart. Junctional rhythms typically have a rate of 40 to 60 beats per minute and may present with inverted or absent P waves on an electrocardiogram (ECG), as the atria and ventricles depolarize simultaneously. This type of rhythm can indicate underlying issues with the heart's normal conduction pathways.
Does Draco kill Dumbledore in Harry Potter and the Deathly Hallows?
No in Half-Blood Prince he tries to but fails so Severus Snape takes over.
What will happen if the sa node is damaged and the pacemaker is not functional?
if the SA node no longer is functional than the AV node will take over giving the hear a slower heart beat
What is backup power source?
the different types of fuels that can be used to produce electricity
What happens if the sinoatrial node fails?
If the AV node could no longer do its job, I think that the ventricles would not be able to contract. The blood could not move to the lungs, nor could it move back. If the AV node could no longer do its job, it would be equivalent to only the top half of the heart working. If only the top half of the heart is working, which means blood is coming from the body into the right atrium, and then the atrium pumps blood into the right ventricle. The ventricle would be swollen because it could not hold so much deoxygenated blood, and eventually, burst. This is because, if the ventricle could not contract, that means there is no way that the ventricle can empty itself out. If the AV node could no longer do its job, then the only part of the heart that would contain blood in it would be the right ventricle, until there is no longer any blood in the body. All of the body's blood would be deoxygenated and in the right ventricle because deoxygenated blood is coming back from the body to the right atrium, and the atrium is contracting, allowing blood into the right ventricle, but no oxygenated blood is leaving the heart, eventually putting all of the blood from the body into the right ventricle. This would eventually lead to death.
What is atrial focus Is it the same as atrial escape?
An atrial focus refers to an ectopic pacemaker located in the atria that can initiate impulses independently of the sinoatrial (SA) node, leading to atrial contractions. It is not the same as atrial escape, which occurs when the SA node fails to generate impulses, allowing an ectopic atrial focus to take over the pacing of the heart. While both involve ectopic activity in the atria, atrial escape specifically pertains to a backup mechanism due to SA node dysfunction.
How does pouring dry sand over the fire blows it?
Pouring dry sand over a fire cuts off the oxygen supply to the flames, which is needed to sustain combustion. By smothering the fire with sand, it helps to extinguish it by removing the element required for burning.
