What is the sequence of travel by an impulse through the cardiac conduction system?

adoni [48]

The sequence of impulse through the cardiac conduction system starts from SA node passes to AV node to atrioventricular bundle fibers and finally to Purkinje fibers.

Heart is an organ that receives oxygenated blood form lungs and deoxygenated blood from different parts of body. Oxygenated blood is transported to different organs and deoxygenated blood is transported to lungs for oxygenation.

Now, to perform this transportation, the auricles and ventricles of heart contract and relax. In order to contract and relax, impulse generation is required, which begins at SA node or Sinoatrial node. It is also referred to as pacemaker of the heart. SA node contracts the atria and the impulse transfers to AV node or Atrioventricular node.

This is followed by transfer of impulse to atrioventricular bundle fibers which further passes it on to Purkinje fibres for ventricular contraction. Now the blood is sent to lungs and aorta as per it's oxygen status.

Aquatic ecologist david strayer of the institute of ecosystem studies and a team of researchers from new york state's department

Sedaia [141]

In communities where zebra mussels have invaded we observed that the population of invertebrates, zooplankton, and phytoplankton they will decrease when in open water. The population of bottom-dwelling invertebrates which are in the littoral zone will increase.
Hypothesis shows the zebra mussels will affect the fish negatively that feed on plankton in the open water but affect positively the fish which feed on invertebrates which are in the littoral zones.
The predictions by following the invasion of zebra muscles show that the number and growth rate of fish species in open water will decrease in population whereas the number and growth rate of fish species in the littoral zone will increase in population.
